74ALVTH32373ZKER Description

The 74ALVTH32373ZKER is a high-performance, dual 8-bit D-type transparent latch with 3-state outputs, manufactured by Texas Instruments as part of the 74ALVTH series. Designed for surface-mount applications, this IC operates across dual voltage ranges (2.3V–2.7V and 3V–3.6V), making it versatile for mixed-voltage systems. Packaged in a 96-ball LFBGA (Tape & Reel), it offers a compact footprint for space-constrained designs. With a propagation delay of just 1ns and robust output drive (8mA source / 24mA sink), it ensures high-speed data transfer and signal integrity. The device is ROHS3 compliant and REACH unaffected, meeting modern environmental standards.
