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 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.
