74LVX373 Low Voltage Octal Transparent Latch with 3-STATE Outputs
June 1993
Revised April 2005
74LVX373
Low Voltage Octal Transparent Latch with
3-STATE Outputs
General Description
The LVX373 consists of eight latches with 3-STATE outputs
for bus organized system applications. The latches appear
transparent to the data when Latch Enable (LE) is HIGH.
When LE is LOW, the data satisfying the input timing
requirements is latched. Data appears on the bus when the
Output Enable (OE) is LOW. When OE is HIGH, the bus
output is in the high impedance state. The inputs tolerate
up to 7V allowing interface of 5V systems to 3V systems.
Features
s
Input voltage translation from 5V to 3V
s
Ideal for low power/low noise 3.3V applications
s
Guaranteed simultaneous switching noise level and
dynamic threshold performance
