Peripheral Drivers
General Description
The DP7310 8310 DP7311 8311 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 input output voltages
and feature a power up clear (outputs off) function
The DP7310 8310 are positive edge latching Two active
low write enable inputs are available for convenient data
bussing without external gating
The DP7311 8311 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
Features
Y High current high voltage open collector outputs
Y Low current high voltage inputs
Y All outputs simultaneously sink rated current ‘‘DC’’ with
no thermal derating at maximum rated temperature
Y Parallel latching or buffering
Y Separate active low enables for easy data bussing
Y Internal ‘‘glitch free’’ power up clear
Y 10% VCC tolerance
Applications
Y High current high voltage drivers
Y Relay drivers
Y Lamp drivers
Y LED drivers
Y TRIAC drivers
Y Solenoid drivers
Y Stepper motor drivers
Y Level translators
Y Fiber-optic LED drivers
