74LCX573 Low Voltage Octal Latch with 5V Tolerant Inputs and Outputs
March 1995
Revised March 2005
74LCX573
Low Voltage Octal Latch with 5V Tolerant
Inputs and Outputs
General Description
The LCX573 is a high-speed octal latch with buffered com-
mon Latch Enable (LE) and buffered common Output
Enable (OE) inputs.
The LCX573 is functionally identical to the LCX373 but has
inputs and outputs on opposite sides.
The LCX573 is designed for low voltage (3.3V or 2.5V)
applications with capability of interfacing to a 5V signal
environment. The LCX573 is fabricated with an advanced
CMOS technology to achieve high speed operation while
maintaining CMOS low power dissipation.
