Functional Description

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

General

The 74LCX273FT is a high-performance CMOS octal D-type flip-flop. Designed for use in 3.3 V systems, it achieves

high-speed operation while maintaining the CMOS low-power dissipation.

The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5 V supply

environment for both inputs and outputs.

This 8 bit D-type flip-flop is controlled by a clock input (CK) and a clear input (CLR). When the CLR input is low,

the eight outputs are at a low logic level.

All inputs are equipped with protection circuits against static discharge.
