Description
SN74ALVCH16245DGGR is a 16-bit bidirectional bus transceiver with 3-state outputs from TI’s ALVCH family. It buffers two 8-bit buses (A and B) and can transfer data in either direction controlled by DIR. An active-low OE disables both sides (tri-states the outputs), allowing multiple devices to share the same bus. Operates on a single low-voltage supply (typical Vcc 1.65–3.6 V) with high-speed, low-power performance suitable for portable and mixed-voltage systems. Applications include interfacing between different voltage domains (e.g., microcontroller and memory), bus buffering, and data path expansion. The DGGR suffix denotes the specific TI package option (to confirm pinout and footprint). For exact electrical specs, timing, and pin assignments, consult the SN74ALVCH16245 datasheet.
