DP7310 DP8310 DP7311 DP8311 Octal Latched 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

All outputs simultaneously sink rated current ‘‘DC’’ with no thermal derating at maximum rated temperature Parallel latching or buffering Separate active low enables for easy data bussing Internal ‘‘glitch free’’ power up clear 10% VCC tolerance
