74LCX574

Low Voltage Octal D-Type Flip-Flop with 5V Tolerant Inputs and Outputs

General Description

The LCX574 is a high-speed, low power octal flip-flop with a buffered common Clock (CP) and a buffered common Output Enable (OE#). The information presented to the D inputs is stored in the flip-flops on the LOW-to-HIGH Clock (CP) transition.

The LCX574 is functionally identical to the LCX374 except for the pinouts.

The LCX574 is designed for low voltage (2.5V or 3.3V) V_CC applications with capability of interfacing to a 5V signal environment. The LCX574 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
