DESCRIPTION
The 74LCX573 is a low voltage CMOS OCTAL
D-TYPE LATCH with 3 STATE OUTPUT
NON-INVERTING fabricated with sub-micron
silicon gate and double-layer metal wiring C2MOS
technology. It is ideal for low power and high
speed 3.3V applications; it can be interfaced to 5V
signal environment for both inputs and outputs.
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. When the LE is
taken low, the Q outputs will be latched 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 (OE) is in high level, the
outputs will be in a high impedance state.
It has same speed performance at 3.3V than 5V
AC/ACT family, combined with a lower power
consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
These 8 bit D-Type latch are controlled by a latch
