TC74VCX574FT, TC74VCX574FK
Low-Voltage Octal D-Type Flip-Flop with 3.6 V Tolerant Inputs and Outputs
The TC74VCX574 is a high performance CMOS octal D-type
flip-flop which is guaranteed to operate from 1.2-V to 3.6-V.
Designed for use in 1.5 V, 1.8 V, 2.5 V or 3.3 V systems, it achieves
high speed operation while maintaining the CMOS low power
dissipation.
It is also designed with over voltage tolerant inputs and outputs
up to 3.6 V.
This 8 bit D-type flip-flop is controlled by a clock input (CK) and
an output enable input (
OE
). When
OE
input is high, the eight
outputs are in a high impedance state.
All inputs are equipped with protection circuits against static
discharge.
