The SN74ALVCHR16245 is a 16-bit noninverting bus transceiver designed for 1.65-V to 3.6-V VCC operation. The device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission Afrom the A bus to the B bus or from the B bus to the bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input controls the output state.
The SN74ALVCHR16245 is a dual‑octal, non‑inverting 16‑bit bus transceiver designed for asynchronous communication between data buses. It can be used as two 8‑bit transceivers or a single 16‑bit transceiver, with direction control (DIR) and output‑enable (OE) inputs to manage data flow and isolation.
Key features include operation from 1.65 V to 3.6 V, 12 mA output drive at 3.3 V, built‑in 26‑Q series resistors on all outputs, bus‑hold circuitry on data inputs, and ESD protection up to 2000 V HBM. The device is offered in SSOP‑DL, TSSOP‑DGG, and VFBGA (GQL/ZQL) packages.
