74LVT32373 • 74LVTH32373

Low Voltage 32-Bit Transparent Latch

with 3-STATE Outputs (Preliminary)

General Description

The LVT32373 and LVTH32373 contain thirty-two non-

inverting latches with 3-STATE outputs and are intended

for bus oriented applications. 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 LVTH32373 data inputs include bushold, eliminating

the need for external pull-up resistors to hold unused

inputs.

These latches are designed for low-voltage (3.3V) VCC

applications, but with the capability to provide a TTL inter-

face to a 5V environment. The LVT32373 and LVTH32373

are fabricated with an advanced BiCMOS technology to

achieve high speed operation similar to 5V ABT while

maintaining a low power dissipation.

Features

s Input and output interface capability to systems at

5V VCC

s Bushold data inputs eliminate the need for external

pull-up resistors to hold unused inputs (74LVTH32373),

also available without bushold feature (74LVT32373)

s Live insertion/extraction permitted

s Power Up/Down high impedance provides glitch-free

bus loading

s Outputs source/sink −32 mA/+64 mA

s ESD performance:

Human-body model > 2000V

Machine model > 200V

Charged-device model > 1000V

s Packaged in plastic Fine-Pitch Ball Grid Array (FBGA)
