General Description
The LCX573 is a high-speed octal latch with buffered
common Latch Enable (LE) and buffered common Out-
put Enable (OE) input.
The LCX573 is functionally identical to the LCX373 but
has inputs and outputs on opposite sides.
The LCX573 is designed for low voltage applications with
capability of interfacing to a 5V signal environment. The
LCX573 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintain-
ing CMOS low power dissipation.

Notes
1. To ensure the high impedance state during power up or down, OE should be tied to V_CC through a pull-up resistor: the minimum
value of the resistor is determined by the current-sourcing capability of the driver.
2. DQFN package available in Tape and Reel only.
3. “_NL” indicates Pb-Free package (per JEDEC J-STD-020B). Device available in Tape and Reel only.
