TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VCX573FT, TC74VCX573FK
Low-Voltage Octal D-Type Latch with 3.6 V Tolerant Inputs and Outputs
The TC74VCX573 is a high performance CMOS octal D-type
latch which is guaranteed to operate from 1.2-V to 3.6-V.
Designed for use in 1.5V, 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 latch is controlled by a latch enable input
(LE) 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
