Peripheral Drivers

General Description

The DP73108310 DP73118311 Octal Latched Peripheral

Drivers provide the function of latching eight bits of data

with open collector outputs each driving up to 100 mA DC

with an operating voltage range of 30V Both devices are

designed for low input currents high inputoutput voltages

and feature a power up clear (outputs off) function

The DP73108310 are positive edge latching Two active

low writeenable inputs are available for convenient data

bussing without external gating

The DP73118311 are positive edge latches The active low

strobe input latches data or allows fall through operation

when held at logic ‘‘0’’ The latches are cleared (outputs off)

with a logic ‘‘0’’ on the clear pin
