Detailed Description

32-bit non-inverting bus transceiver, configured as four 8-bit segments. Operates at 2.7 to 3.6 V, delivers up to 24 mA per output, and supports 3-state outputs for bus sharing. Industrial temperature range from -40 to +85 C. Packaged in 96-ball CABGA/LFBGA, supplier device package 96-CABGA (13.5 x 5.5 mm). RoHS non-compliant.

Key Features

32-bit bus width split into 4 x 8-bit elements for flexible design

Non-inverting transceiver logic for clean, direct signal transfer

3-state outputs for easy bus isolation and multiplexing

High drive strength ±24 mA per output

Wide supply range 2.7 to 3.6 V

Surface-mount BGA footprint for compact layouts

Industrial temperature rating -40 to +85 C

Part of the 74ALVCH high-speed, low-voltage CMOS logic series

Key Advantages

Moves data in both directions between two buses with simple control

Preserves signal polarity, reducing logic complexity

Strong drive capability supports longer traces and heavier loads

3-state outputs minimize bus contention and allow shared lines

Compact BGA reduces PCB area and can improve signal integrity

Low-voltage CMOS helps lower power vs. older 5 V families
