Description
Pericom Semiconductor’s PI74LPT374 8-bit wide octal
resisters designed with eight D-type flip-flops, a buffered
common clock, and buffered 3-state outputs. When
output enable (OE)
When OE is HIGH, the outputs are in the high impedance state.
Input data meeting the setup and hold time requirements of the
D inputs is transferred to the O outputs on the LOW-to-HIGH
transition of the clock input.
The PI74LPT374 can be driven from either 3.3V or 5.0V devices
allowing for the device to be used as a translator in a mixed
3.3V/5.0V system.
