DP7310/DP8310/DP7311/DP8311 Octal Latched
Peripheral Drivers
Y
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.

Note 1: ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed. Except for ‘‘Operating Temperature Range’’
they are not meant to imply that the devices should be operated at these limits. The table of ‘‘Electrical Characteristics’’ provides conditions for actual device
operation.
Note 2: Unless otherwise specified min/max limits apply across the b 55§ C to a 125§ C temperature range for the DP7310/DP7311 and across the 0§ C to a 70§ C
for the DP8310/DP8311. All typical values are for TA e 25§ C, VCC e 5V.
Note 3: All currents into device pins shown as positive, out of device pins as negative, all voltages referenced to ground unless otherwise noted.
Note 4: Input capacitance is guaranteed by periodic testing. fTEST e 10 kHz at 300 mV, TA e 25§ C.

Note 1: Always use good VCC bypass and ground techniques to suppress transients caused by peripheral loads.
Note 2: Printed circuit board mounting is required if these devices are operated at maximum rated temperature and current (all outputs on DC).
