Low-Voltage 20-Bit D-Type Flip-Flop with 3.6-V Tolerant Inputs and Outputs
D-type flip-flop. Designed for use in 1.8-V, 2.5-V or 3.3-V systems,
it achieves high-speed operation while maintaining the CMOS
low power dissipation.

identically, but independent of the other. Control pins can be
shorted together to obtain full 20-bit operation. The following
description applies to each byte. The twenty flip-flops will store
the state of their individual D inputs that meet the setup and
hold time requirements on the LOW-to-HIGH Clock (CK)
transition. When the OE input is high, the outputs are in a high-impedance state. This device is designed to be
used with 3-state memory address drivers, etc.
Features
The TC74VCX16821FT is a high-performance CMOS 20-bit
It is also designed with overvoltage tolerant inputs and outputs
The device is byte controlled with each byte functioning
All inputs are equipped with protection circuits against static discharge.
