Functional Description

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

General

The 74LCX74FT is a high-performance CMOS 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 inputs.

The signal level applied to the D input is transferred to Q output during the positive going transition of the CK

pulse.

CLR and PR are independent of the CK and are accomplished by setting the appropriate input low.

All inputs are equipped with protection circuits against static discharge.
