General Description
The LCX373 consists of eight latches with 3-STATE out-
puts for bus organized system applications. The device is
designed for low voltage applications with capability of
interfacing to a 5V signal environment.
The LCX373 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintain-
ing CMOS low power dissipation.

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
Pb-Free package per JEDEC J-STD-020B.
Notes:
1. To ensure the high impedance state during power up or down, OE should be tied to VCC 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.

Functional Description
The LCX373 contains eight D-type latches with 3-STATE
standard outputs. When the Latch Enable (LE) input is
HIGH, data on the Dn inputs enters the latches. In this
condition the latches are transparent, i.e. a latch output
will change state each time its D input changes. When
LE is LOW, the latches store the information that was
present on the D inputs a setup time preceding the
HIGH-to-LOW transition of LE. The 3-STATE standard
outputs are controlled by the Output Enable (OE) input.
When OE is LOW, the standard outputs are in the 2-state
mode. When OE is HIGH, the standard outputs are in the
high impedance mode but this does not interfere with
entering new data into the latches.
