Product Description
Pericom Semiconductor's PI74LCX series of logic circuits are produced using the Company's advanced 0.6 CMOS technology, achieving industry leading speed grades. The PI74LCX374 is an 8-bit wide octal D-type flip flop designed with a buffered common clock and buffered 3-state outputs. When output enable (OE) is LOW, the outputs are enabled. 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 PI74LCX374 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.
