DP8310/DP8311

Octal Latched Peripheral Drivers

General Description

The DP8310 and DP8311 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 op-

erating voltage range of 30V. Both devices are designed for

low input currents, high input/output voltages, and feature a

power up clear (outputs off) function.

The DP8310 is positive edge latching. Two active low write/

enable inputs are available for convenient data bussing with-

out external gating.

The DP8311 is positive edge latching. 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.
