DP8310/DP8311
Octal Latched Peripheral Drivers
n All outputs simultaneously sink rated current “DC” with
no thermal derating at maximum rated temperature
n Parallel latching or buffering
n Separate active low enables for easy data bussing
n Internal “glitch free” power up clear
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.
%
n 10 VCC tolerance
Applications
n High current high voltage drivers
n Relay drivers
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.
