DESCRIPTION
The 74LVX573 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 C
2
MOS
technology. It is ideal for low power, battery
operated and low noise 3.3V applications.
This 8 bit D-Type latch is controlled by a latch
enable input (LE) and an output enable input (OE).
While the LE input is held at a high level, the Q
outputs will follow the data input precisely.
PIN CONNECTION AND IEC LOGIC SYMBOLS
When the LE is taken low, the Q outputs will be
latched precisely 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.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage.
This device can be used to interface 5V to 3V. It
combines high speed performance with the true
CMOS low power consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
