This is a 16-bit dual-supply bus transceiver with configurable voltage translation and 3-state outputs.
The SN74AVCBH164245 is a 16‑bit (dual‑octal) non‑inverting bus transceiver that provides bidirectional data translation between two voltage domains (1.5 V, 1.8 V, 2.5 V, 3.3 V). It features configurable dual‑rail power supplies, active bus‑hold circuitry, and 3‑state outputs controlled by direction (DIR) and output‑enable (OE) pins.
The device is specified for operation from –40 °C to 85 °C, supports partial‑power‑down mode, and includes ESD protection up to 2000 V HBM. Detailed electrical characteristics, absolute maximum ratings, and switching parameters are provided for the TSSOP, DGG, DGV, and VFBGA‑GQL packages.
