74VCXHR162245 is a low voltage CMOS 16 bit bus transceiver (3-state)
The 74VCXHR162245 is a low‑voltage CMOS 16‑bit bus transceiver featuring 3‑state outputs, series resistors on both A and B ports, and built‑in bus‑hold. It operates from 2.3 V to 3.6 V and includes protection against static discharge (HBM > 2000 V, MM > 200 V). The device is intended for two‑way asynchronous communication between data buses, with direction controlled by the DIR input.
Key electrical characteristics include a typical propagation delay of 2.3 ns to 2.7 ns, high‑speed output transition times of 3.4 ns (max) at 3.0 V, and a power dissipation rating of 400 mW. Absolute maximum supply voltage is –0.5 V to +4.6 V, and recommended operating conditions specify a supply range of 2.3 V to 3.6 V. Mechanical data for the TSSOP48 package are also provided.
