Functional Description

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

General

The 74LCX374FT 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 an output enable input (OE).

When the OE input is high, the eight outputs are in a high-impedance state.

All inputs are equipped with protection circuits against static discharge.

Features

(1) Low-voltage operation: VCC = 1.65 to 3.6 V

(2) High-speed operation: tpd = 8.5 ns (max) (VCC = 3.0 to 3.6 V)

(3) Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V)

(4) Power-down protection provided on all inputs and outputs

(5) Pin and function compatible with the 74 series

(74LVC/ALVC/ etc.) 374 type
