DESCRIPTION

The 74LVC573A is a low voltage CMOS OCTAL

D-TYPE LATCH fabricated with sub-micron silicon

gate and double-layer metal wiring C2MOS

technology. It is ideal for 1.65 to 3.6 VCC

operations

and

low

power

and

low

noise

applications.

These 8 bit D-Type latch are controlled by a latch

enable input (LE) and an output enable input (OE).

While the LE inputs is held at a high level, the Q

outputs will follow the data input precisely or

inversely. When the LE is taken low, the Q outputs

will be latched precisely or inversely at the logic

level of D input data. While the (OE) input is low,

the 8 outputs will be in a normal logic state (high or

low logic level) and while high level the outputs will

be in a high impedance state.

This device is designed to interface directly High

Speed CMOS systems with TTL and NMOS

components. It has more speed performance at

3.3V than 5V AC/ACT family, combined with a

lower power consumption.

All inputs are equipped with protection circuits

against static discharge, giving them 2KV ESD

immunity and transient excess voltage.
