74LCX16373

Low Voltage 16-Bit Transparent Latch

with 5V Tolerant Inputs and Outputs

General Description

The LCX16373 contains sixteen non-inverting latches with

3-STATE outputs and is intended for bus oriented applica-

tions. The device is byte controlled. The flip-flops appear

transparent to the data when the Latch Enable (LE) is

HIGH. When LE is LOW, the data that meets the setup time

is latched. Data appears on the bus when the Output

Enable (OE) is LOW. When OE is HIGH, the outputs are in

a high impedance state.

The LCX16373 is designed for low voltage (2.5V or 3.3V)

VCC applications with capability of interfacing to a 5V signal

environment.

The LCX16373 is fabricated with an advanced CMOS tech-

nology to achieve high speed operation while maintaining

CMOS low power dissipation.

Features

s 5V tolerant inputs and outputs

s 2.3Vâ3.6V VCC specifications provided

s 5.4 ns tPD max (VCC 3.3V), 20 PA ICC max

s Power down high impedance inputs and outputs

s Supports live insertion/withdrawal (Note 1)

s r24 mA output drive (VCC 3.0V)

s Uses patented noise/EMI reduction circuitry

s Latch-up performance exceeds 500 mA

s ESD performance:

Human body model ! 2000V

Machine model ! 200V

s Also packaged in plastic Fine-Pitch Ball Grid Array

(FBGA)

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.
