74LCX573WMX Low Voltage Octal Latch with 5V Tolerant Inputs and Outputs

74LCX573WMX

Low Voltage Octal Latch with 5V Tolerant Inputs and Outputs

General Description

The LCX573 is a high-speed octal latch with buffered common 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.

Features

■ 5V tolerant inputs and outputs  

 ■ 2.3V–3.6V VCC specifications provided

■ 7.0 ns tPD max (VCC 3.3V), 10 PA ICC max

 ■ Power down high impedance inputs and outputs

■ Supports live insertion/withdrawal (Note 1)  

■ r24 mA output drive (VCC 3.0V)

■ Implements patented noise/EMI reduction circuitry  

■ Latch-up performance exceeds JEDEC 78 conditions

■ ESD performance: Human body model ! 2000V Machine model ! 200V

■ Leadless Pb-Free DQFN package

Note 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 or the resistor is determined by the current-sourcing capability of the driver.
