DP8310/DP8311 Octal Latched Peripheral Drivers
February 2000
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 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 DP8310 is positive edge latching. Two active low write/
enable inputs are available forconvenientdatabussingwithout 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.
Features
n High current, high voltage open collector outputs

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 0˚C to +70˚C for the DP8310/DP8311. All typical values are for T
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. f
