16-bit bus transceiver for mixed-voltage backplanes
It handles bidirectional data flow between two buses, with 3-state outputs that let multiple drivers share a bus line without contention.
Each output sources or sinks 24 mA, which is enough to drive a heavily loaded parallel bus with multiple fan-outs or long PCB traces. In a typical 5V backplane with 10-15 loads, that drive strength keeps the signal edges clean without needing a separate bus buffer. The 3-state outputs let you disconnect the transceiver from the bus when it's not the active driver — essential for shared data lines where only one device talks at a time.
Package and temperature grade
Housed in a 48-BSSOP (SSOP) package with 0.295" body width and 7.50 mm pitch, this is a surface-mount part that sits flat on the board — no through-hole leads to route.
