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

The TC74LCX273 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.

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.

Features

• Latch-up performance: −500 mA

• Available in JEITA SOP, TSSOP and VSSOP (US)

• Power-down protection is provided on all inputs and outputs

• Pin and function compatible with the 74 series

(74AC/VHC/HC/F/ALS/LS etc.) 273 type
