Receivers
DETAꢁLED DESCRꢁPTꢁꢀꢂ
The receivers convert EIA/TIA-232 signal lev-
els to inverted TTL or CMOS logic output lev-
els. Since the input is usually from a transmis-
sion line, where long cable length and system
interference can degrade the signal, the inputs
have a typical hysteresis margin of 500mV. This
ensures that the receiver is virtually immune to
noisy transmission lines. The input thresholds
are 0.8V minimum and 2.8V maximum, again
well within the +/-3V RS-232 requirements.
Should an input be left unconnected, an internal
5kohm pull-down resistor to ground will commit
the output of the receiver to a HIGH state.
The SP202E, SP232E, SP233E, SP3ꢀ0E and
SP3ꢀ2A devices are a family of line driver and
receiver pairs that meet the EIA/TIA-232 and
V.28 serial communication protocols. The ESD
tolerance has been improved on these devices
to over +/-ꢀ5kV for Human Body Model. These
devices are pin-to-pin compatible with Exar's
232A, 233A, 3ꢀ0A and 3ꢀ2A as well as popular
industry standards. This family of parts offer a
ꢀ20kbps data rate, ꢀ0V/μs slew rate and an on-
board charge pump that operates from a single
5V supply using 0.ꢀμF ceramic capacitors.
The SP202E, 232E, 233E, 3ꢀ0E and 3ꢀ2E de-
vices have internal charge pump voltage con-
verters which allow them to operate from a sin-
gle +5V supply. The charge pumps will operate
with polarized or non-polarized capacitors rang-
ing from 0.ꢀ to ꢀ0µF and will generate the +/-6V
needed to generate the RS-232 output levels.
In actual system applications, it is quite pos-
sible for signals to be applied to receiver inputs
before power is applied to the receiver circuitry.
This occurs, for example, when a PC user at-
tempts to print, only to realize that the printer
wasn't turned on. In this case an RS-232 signal
from the PC will appear on the receiver input
at the printer. When the printer power is turned
on, the receiver will operate normally. All of
these devices are fully protected.
The SP233E design offers internal charge pump
capacitors. The SP3ꢀ0E provides an ON/OFF
input that simultaneously disables the internal
charge pump circuit and puts all transmitter and
receiver outputs into a high impedance state.
The SP3ꢀ2E is identical to the SP3ꢀ0E but with
seperate tri-state and shutdown inputs
Charge pump
The charge pump is an Exar patented design
and uses a unique approach compared to
older less efficiant designs. The charge pump
requires 4 external capacitors and uses a four
phase voltage shifting technique. The internal
power supply consists of a dual charge pump
that provides a driver output voltage swing of
+/-6V. The internal oscillator controls the four
phases of the voltage shifting. A description of
each phase follows:
Theory ꢀf ꢀperation
The SP202E, SP232E, SP233E, SP3ꢀ0E and
SP3ꢀ2E devices are made up of three basic
circuit blocks: 1. Drivers, 2. Receivers, and 3.
charge pump. Each block is described below.
Drivers
The drivers are inverting level transmitters that
convert TTL or CMOS logic levels to EIA/TIA-
232 levels with an inverted sense relative to
the input logic levels. The typical driver output
voltage swing is +/-6V. Even under worst case
loading conditions of 3k ohms and 2500pF, the
driver output is guaranteed to be +/-5.0V mini-
mum, thus satisfying the RS-232 specification.
The driver outputs are protected against infinite
short-circuits to ground without degradation in
reliability.
Phase 1
Vss charge store and double: The positive ter-
minals of capacitors Cꢀ and C2 are charged
from Vcc with their negative terminals initially
connected to ground. Cꢀ+ is then connected
to ground and the stored charge from Cꢀ- is
superimposed onto C2-. Since C2+ is still con-
nected to Vcc the voltage potential across C2
is now 2 x Vcc.
Phase 2
Vss transfer and invert: Phase two connects
the negative terminal of C2 to the Vss storage
capacitor and the positive terminal of C2 to
ground. This transfers the doubled and invert-
ed (V-) voltage onto C4. Meanwhile, capacitor
The slew rate of the driver output is internally
limited to 30V/μs in order to meet the EIA stan-
dards (EIA-232F). Additionally, the driver out-
puts LOW to HIGH transition meets the mon-
tonic output requirements of the standard.

DESCRꢁPTꢁꢀꢂ
Cꢀ is charged from Vcc to prepare it for its next
phase.
Wake-Up Feature for the SP312E
The SP3ꢀ2E has a wake-up feature that keeps
the receivers active when the device is placed
into shutdown. Table 1 defines the truth table for
the Wake-Up function. When only the receivers
are activated, the SP3ꢀ2E typically draws less
than 5uA supply current. In the case of when
a modem is interfaced to a computer in power
down mode, the Ring Indicator (RI) signal from
the modem would be used to "wake-up" the
computer, allowing it to accept data transmis-
sion.
Phase 3
Vdd charge store and double: Phase three is
identical to the first phase. The positive termi-
nals of Cꢀ and C2 are charged from Vcc with
their negative terminals initially connected to
ground. Cꢀ+ is then connected to ground and
the stored charge from Cꢀ- is superimposed
onto C2-. Since C2+ is still connected to Vcc
the voltage potential across capacitor C2 is now
2 x Vcc.
After the ring indicator has propagated
through the SP3ꢀ2E receiver, it can be used
to trigger the power management circuitry of
the computer to power up the microproces-
sor, and bring the SD pin of the SP3ꢀ2E to a
logic high, taking it out of the shutdown mode.
The receiver propagation delay is typically
ꢀus. The enable time for V+ and V- is typi-
cally 2ms. After V+ and V- have settled to their
final values, a signal can be sent back to the
modem on the data terminal ready (DTR) pin
signifying that the computer is ready to accept
the transmit data.
Phase 4
Vdd transfer: The fourth phase connects the
negative terminal of C2 to ground and the posi-
tive terminal of C2 to the Vdd storage capacitor.
This transfers the doubled (V+) voltage onto C3.
Meanwhile, capacitor Cꢀ is charged from Vcc to
prepare it for its next phase.
The clock rate for the charge pump typically op-
erates at greater than ꢀ5kHz allowing the pump
to run efficiently with small 0.1uF capacitors. Ef-
ficient operation depends on rapid charging and
discharging of Cꢀ and C2, therefore capacitors
should be mounted as close as possible to the
IC and have low ESR (equivalent series resis-
tance). Inexpensive surface mount, ceramic ca-
pacitors are ideal for using on charge pump. If
polarized capacitors are used the positive and
negative terminals should be connected as
shown in the typical operating circuit. A diagram
of the individual phases are shown in Figure ꢀ.

Pin Strapping for the SP233E
To operate properly, the following pairs of pins
must be externally wired together as noted in
table 2:
Both the SP3ꢀ0E and SP3ꢀ2E have a shutdown
/ standby mode to conserve power in battery-
powered applications. To activate the shutdown
mode, which stops the operation of the charge
pump, a logic "0" is applied to the appropriate
control line. For the SP3ꢀ0E, this control line is
the ON/OFF (pin ꢀ8) input. Activating the shut-
down mode puts the SP3ꢀ0E transmitter and
receiver ouptuts into a high impedance con-
dition. For the SP3ꢀ2E, this control line is the
SHUTDOWN (pinꢀ8) input; this also puts the
transmitter outputs in a tri-state mode. The re-
ceiver outputs can be tri-stated seperately dur-
ing normal operation or shutdown by applying a
logic "ꢀ" on the EN line (pin ꢀ).

The premise of this ESD test is to simulate
the human body's potential to store electro-
static energy and discharge it to an intergrated
circuit. The simulation is peformed by using a
test model as shown in figure 2. This method
will test the IC's capability to withstand an ESD
transient during normal handling such as in
manufacturing areas where the IC's tend to be
handled frequently.
ESD TꢀLERAꢂCE
The SP202E, 232E, 233E, 3ꢀ0E and 3ꢀ2E
devices incorporates ruggedized ESD cells on
all driver outputs and receiver input pins. The
ESD structure is improved over our previous
family for more rugged applications and envi-
ronments sensitive to electro-static discharges
and associated transients. The improved ESD
tolerance is at least +/-ꢀ5kV Human Body
Model without damage nor latch-up.
