DESCRIPTION…
The SP333 is a monolithic device that supports both Macintosh™ and PC serial interfaces.
RS-232 mode offers three (3) RS-232 drivers and five (5) RS-232 receivers. Mac mode
includes a differential driver and a single-ended inverting driver. Receivers in Mac mode
include one differential receiver, one non-inverting single-ended receiver and one inverting
single-ended receiver. An on-chip charge pump allows +5V-only operation, and a low power

THEORY OF OPERATION...
The single-ended AppleTalk driver also has
typical voltage output swings of ±5V under
loaded conditions, and ±8V under no-load con-
ditions. The single-ended AppleTalk driver can
maintain ±3.6V (minimum) swings under worst
case conditions of 450Ω to ground. The single-
ended AppleTalk driver can support data rates
over 400kbps.
The SP333 is a single chip device that can be
configured via software for either RS-232 or
AppleTalk™ interface modes at any time. The
SP333 is made up of three basic circuit ele-
ments: single-ended drivers and receivers, dif-
ferentialdriversandreceivers,andchargepump.
APPLETALK™ DRIVERS/RECEIVERS...
The receiver section of the SP333 is made up of
a differential receiver, a single-ended non-in-
verting receiver , and a single-ended inverting
receiver. The differential receiver has an input
sensitivity of ±200mV over a common mode
range of ±7V. The receivers have a typical input
resistance of 15kΩ (12kΩ minimum). The
differential receiver can receive data up to
10Mbps.
To program the SP333 for MacMode, Pin 25
should be connected to a logic HIGH. In
MacMode, the SP333 offers a complete
AppleTalk serial interface.
The driver section of the AppleTalk interface is
made up of a differential driver and a single-
ended inverting driver. The differential driver
has voltage swings that are typically ±5V on
each output pin under loaded conditions, and
typically ±8V under no-load conditions. The
differential driver can maintain ±3.6V (mini-
mum) swings (per pin) under worst case load
conditions of 450Ω between the differential
output.
The single-ended non-inverting receiver has a
±200mV input threshold, however, the input
voltage can vary between ±7V. The typical
input resistance of the single-ended non-invert-
ing receiver is 15kΩ (12kΩ minimum). The
single-ended non-inverting receiver can also
receive data up to 10Mbps.
The differential driver is equipped with a tri-
state control pin. When TXEN is a logic LOW,
thedifferentialdriverisactive. WhentheTXEN
pin is a logic HIGH, the differential driver
outputs are tri-stated. The TXEN pin only
functions in MacMode. The differential
AppleTalk driver can support data rates up to
10Mbps.
The SP333 also has a single-ended inverting
receiver input. This receiver is basically an RS-
232 receiver (R5 receiver) and is typically used
as a GPI (General Purpose Input) in the
AppleTalk interface. The GPI input has TTL-
compatible input thresholds that can receive

signals up to ±15V. The input resistance of the
single-ended inverting receiver is typically 5kΩ
(3kΩ to 7kΩ). The GPI receiver can operate up
to 10Mbps.
receivers features 500mV of hysteresis margin
to minimize the affects of noisy tranmission
lines. The inputs also have a 5kΩ resistor to
ground, in an open circuit situation the input of
the receiver will be forced low, committing the
output to a logic HIGH state. The input resis-
tancewillmaintain3kΩ-7kΩovera±15Vrange.
The maximum operating voltage range for the
receiver is ±30V, under these conditions the
input current to the receiver must be limited to
less than 100mA. Due to the on-chip ESD pro-
tection circuitry, the receiver inputs will be
clamped to ±15V levels; this should not affect
operation at ±30Volts. The RS-232 receivers
can operate over 400kbps.
SINGLEENDEDDRIVERS/RECEIVERS...
RS-232 (V.28) Drivers...
The single-ended drivers and receivers comply
the with the RS-232E and V.28 standards. The
drivers are inverting transmitters which accept
either TTL or CMOS inputs and output the RS-
232 signals with an inverted sense relative to the
input logic levels. Typically, the RS-232 driver
output voltage swing is ±9V with no load and is
guaranteed to be greater than ±5V under full
load. The drivers rely on the V+ and V- voltages
generated by the on-chip charge pump to main-
tain proper RS-232 output levels. With worst
case load conditions of 3kΩ and 2500pF, the
four RS-232 drivers can still maintain ±5V
output levels. The drivers can operate over
400kbps; the propagation delay from input to
output is typically 1.5µs. During shutdown, the
driver outputs will be put into a high impedance
tri-state mode.
CHARGE PUMP...
The charge pump is a Sipex-patented design
(5,306,954) and uses a unique approach com-
pared to older less-efficient designs. The charge
pump still requires four external capacitors, but
uses a four-phase voltage shifting technique to
attain symmetrical 10V power supplies. The
capacitor values of the SP333 can be as low as
0.1µF. Figure 11a shows the waveform found
on the positive side of capacitor C2, and Figure
11b shows the negative side of capacitor C2.
There is a free-running oscillator that controls
the four phases of the voltage shifting. A de-
scription of each phase follows.
RS-232 (V.28) Receivers...
The RS-232 receivers convert RS-232 input
signals to inverted TTL signals. Each of the four

the Vdd storage capacitor. Simultaneously with
this, thepositivesideofcapacitorC1isswitched
to +5V and the negative side is connected to
ground, and the cycle begins again.
Phase 1
-Vss charge storage- During this phase of the
clock cycle, the positive side of capacitors C1
and C2 are initially charged to +5V. C1+ is then
switched to ground and charge in C1- is trans-
ferred to C2-. Since C2+ is connected to +5V,
the voltage potential across capacitor C2 is
now 10V.
Since both V+ and V- are separately generated
from Vcc in a no load condition, V+ and V- will
be symmetrical. Older charge pump approaches
that generate V- from V+ will show a decrease
in the magnitude of V- compared to V+ due to
the inherent inefficiencies in the design.
Phase 2
-Vss transfer- Phase two of the clock connects
the negative terminal of C2 to the Vss storage
capacitor and the positive terminal of C2 to
ground, and transfers the generated -10V to C3.
Simultaneously, the positive side of capacitor
C1 is switched to +5V and the negative side is
connected to ground.
The clock rate for the charge pump typically
operatesat15kHz.Theexternalcapacitorsshould
be 0.1µF with a 16V breakdown rating.
External Power Supplies
For applications that do not require +5V only,
external supplies can be applied at the V+ and
V- pins. The value of the external supply volt-
ages must be no greater than ±10V. The current
drain from the ±10V supplies is used for the RS-
232 drivers. For the RS-232 driver, the current
requirement is 3.5mA per driver. The external
power supplies should provide a power supply
sequence of either: +10V, –10V, and then +5V;
or –10V, +10V, and then +5V. It is critical that
the ±10V supplies are on before VCC.
Phase 3
-Vdd charge storage- The third phase of the
clock is identical to the first phase- the trans-
ferredchargeinC1produces-5Vinthenegative
terminal of C1, which is applied to the negative
side of capacitor C2. Since C2+ is at +5V, the
voltage potential across C2 is 10V.

Shutdown Mode
The SP333 can be put into a low power shut-
down mode by connecting the Shutdown pin
(SD, Pin 26) to a logic HIGH. During Shut-
down, the driver outputs are put into a high
impedance tri-state, and the charge pump is put
intostand-bymode. Thesupplycurrentdropsto
less than 10µA during shutdown and can be
activated in either RS-232 or AppleTalk mode.
For normal operation, the SD pin should be
connected to a logic LOW.
Receiver Enable
The SP333hasacontrollinetoenableordisable
the receiver outputs. Pin 3 (RXEN) is active
LOW; a logic LOW on Pin 3 will enable the
receiver outputs. A logic HIGH on Pin 3 will
disable the receiver outputs. The receiver en-
ablefunctioncanbeinitiatedineitherRS-232or
AppleTalk mode.
Wake-Up
The SP333 also features a "wake-up" function.
ThewakeupfunctionallowstheRS-232receiv-
ers to remain active during Shutdown mode
unless they are disabled by the Receiver Enable
control pin (Pin 3). The wake-up feature allows
