Low-voltage 12-bit 1:2 mux / demux bus switch with internal pull down resistors
The IDT74CBTLV16292 is a single 12‑bit multiplexing/demultiplexing bus switch designed for low‑voltage operation. It features bi‑directional switching, isolation under power‑off, make‑before‑break, over‑voltage tolerance, and an internal 500 Ω pull‑down resistor to ground.
The document provides pin configuration, absolute maximum ratings, electrical and switching characteristics, test circuits, and ordering information. It also lists typical propagation delay (0.15‑0.25 ns) and make‑before‑break time (0‑2 ns), making it useful for designers of high‑speed bus systems.
