16-BIT SERIAL-INPUT, CONSTANT-
CURRENT LATCHED LED DRIVER
The A6276 is specifically designed for LED-display applications.
Each BiCMOS device includes a 16-bit CMOS shift register, accom-
panying data latches, and 16 npn constant-current sink drivers. Except
for package style and allowable package power dissipation, the device
options are identical.
The CMOS shift register and latches allow direct interfacing with
microprocessor-based systems. With a 5 V logic supply, typical serial
data-input rates are up to 20 MHz. The LED drive current is deter-
mined by the user’s selection of a single resistor. A CMOS serial data
output permits cascade connections in applications requiring additional
drive lines. For inter-digit blanking, all output drivers can be disabled
with an ENABLE input high. Similar 8-bit devices are available as the
A6275EA and A6275ELW.
Three package styles are provided: through-hole DIP (suffix A),
surface-mount SOIC (suffix LW) and TSSOP with exposed thermal pad
(suffix LP). Under normal applications, a copper lead frame and low
logic-power dissipation allow the dual in-line package to sink maxi-
mum rated current through all outputs continuously over the operating
temperature range (90 mA, 0.75 V drop, +85°C).

*Pb-based variants are being phased out of the product line. The variants cited in this
footnote are in production but have been determined to be NOT FOR NEW DESIGN.
This classification indicates that sale of this device is currently restricted to existing
customer applications. The variants should not be purchased for new design applica-
tions because obsolescence in the near future is probable. Samples are no longer
available. Status change: May 1, 2006. These variants include:A6276EA, A6276ELW,
A6276ELWTR, A6276SA, A6276SLW, and A6276SLWTR.

Caution: These CMOS devices have input static
protection (Class 2) but are still susceptible
to damage if exposed to extremely high static

Serial data present at the input is transferred to the shift
register on the logic 0-to-logic 1 transition of the CLOCK input
pulse. On succeeding CLOCK pulses, the registers shift data in-
formation towards the SERIAL DATA OUTPUT. The serial data
must appear at the input prior to the rising edge of the CLOCK
input waveform.
Information present at any register is transferred to the
respective latch when the LATCH ENABLE is high (serial-to-
parallel conversion). The latches continue to accept new data as
long as the LATCH ENABLE is held high. Applications where
the latches are bypassed (LATCH ENABLE tied high) will
require that the OUTPUT ENABLE input be high during serial
data entry.
When the OUTPUT ENABLE input is high, the output sink
drivers are disabled (OFF). The information stored in the latches
is not affected by the OUTPUT ENABLE input. With the OUT-
PUT ENABLE input low, the outputs are controlled by the state
of their respective latches.

Applications Information
The load current per bit (IO) is set by the external resistor
(REXT) as shown in the figure below.
diode (VZ), or a series string of diodes (approximately
0.7 V per diode) for a group of drivers. If the available
voltage source will cause unacceptable dissipation and
series resistors or diode(s) are undesirable, a regulator
such as the Sanken Series SAI or Series SI can be used to
provide supply voltages as low as 3.3 V.
For reference, typical LED forward voltages are:
White

3.5 – 4.0 V
3.0 – 4.0 V

2.0 – 2.1 V

1.6 – 2.25 V

Pattern Layout. This device has a common logic-
ground and power-ground terminal. If ground pattern lay-
out contains large common-mode resistance, and the volt-
age between the system ground and the LATCH ENABLE
or CLOCK terminals exceeds 2.5 V (because of switching
noise), these devices may not operate correctly.
Package Power Dissipation (PD). The maximum al-
lowable package power dissipation is determined as
PD(max) = (150 - TA)/RθJA
.
The actual package power dissipation is
PD(act) = DC • (VCE • IO • 16) + (VDD • IDD) ,
where DC is the duty cycle.
When the load supply voltage is greater than 3 V to 5 V,
considering the package power dissipating limits of these
devices, or if PD(act) > PD(max), an external voltage re-
ducer (VDROP) should be used.
Load Supply Voltage (VLED). These devices are de-
signed to operate with driver voltage drops (VCE) of
0.4 V to 0.7 V with LED forward voltages (VF) of 1.2 V to
4.0 V. If higher voltages are dropped across the driver,
package power dissipation will be increased significantly.
To minimize package power dissipation, it is recom-
mended to use the lowest possible load supply voltage or
to set any series dropping voltage (VDROP) as
VDROP = VLED - VF - VCE
with VDROP = Io • RDROP for a single driver, or a Zener
