74LCX573
Low Voltage Octal Latch with 5V Tolerant
Inputs and Outputs
Features
■ 5V tolerant inputs and outputs
■ 2.3V–3.6V V_CC specifications provided
■ 7.0 ns t_PD max. (V_CC = 3.3V), 10µA I_CC max.
■ Power down high impedance inputs and outputs
■ Supports live insertion/withdrawal⁽¹⁾
■ ±24mA output drive (V_CC = 3.0V)
■ Implements proprietary noise/EMI reduction circuitry
■ Latch-up performance exceeds JEDEC 78 conditions
■ ESD performance
– Human body model > 2000V
– Machine model > 200V
■ Leadless DQFN package
Note:
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.
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
maintaining CMOS low power dissipation.
