The UCN5816A and UCN5816EP 4-to-16 line latched decoder/
drivers combine low-power CMOS inputs and logic with 16 highcurrent, 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 transientsuppression 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 surfacemount applications. Both devices will drive 350 mA loads continuously
over the full operating temperature range.
