4-TO-16 LINE
LATCHED DECODER/DRIVERS
The UCN5816A and UCN5816EP 4-to-16 line latched decoder/
drivers combine low-power CMOS inputs and logic with 16 high-
current, high-voltage bipolar outputs. The CMOS inputs cause minimal
loading and are compatible with standard CMOS, PMOS, and NMOS
logic. TTL or DTL circuits may require the use of appropriate pull-up
resistors to ensure an input logic high. The logic operates over a
supply range of 5 V to 12 V. A CHIP ENABLE function can be used
with two devices for 5-to-32 line decoding applications.

The 16 bipolar power outputs are open-collector 60 V Darlington
drivers capable of sinking 350 mA continuously. Internal transient-
suppression diodes provide protection for use with inductive loads.
For ink-jet printer applications, the A5817SEP addressable 28-line
decoder/driver is recommended.

The UCN5816A is supplied in a 28-pin dual in-line plastic package
with 0.600" (15.24 mm) row spacing. The UCN5816EP is furnished in
a 28-lead plastic chip carrier (quad pack) for minimum-area surface-
mount applications. Both devices will drive 350 mA loads continuously
over the full operating temperature range.

Information present at the inputs is

F
transferred to the latches when the STROBE
is high. The latches will continue to accept
new data as long as the STROBE is held
high. With the STROBE in the low state, no
information can be loaded into the latches.
Depending on the four address inputs, the
4-to-16 line decoder enables one of the
16 output sink drivers. When the OUTPUT
ENABLE is high, all of the outputs are
disabled (OFF) without affecting the informa-
tion stored in the latches. When the OUT-
PUT ENABLE is low, the outputs are con-
trolled by the information in the latches.
When the CHIP ENABLE is low, all of the
outputs are disabled (OFF). With two de-
coder/drivers and an inverter, the CHIP
ENABLE function can be used for 5-to-32 line
decoding applications.
