description

The 'AC16862 and 'ACT16862 are inverting 20-bit bus transceivers composed of two 10-bit transceiver sections with separate control signals. These devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the levels present at the output-enable inputs (1G\AB, 2G\AB, 1G\BA, and 2G\BA). The control logic also allows for isolation and latching.

The 74AC16862 and 74ACT16862 are packaged in TI's shrink small-outline package (SSOP) with 25-mil center-to-center pin spacings. This package provides twice the I/O pin count and functionality of a standard small-outline package in the same printed-circuit-board area.

The 'AC16862 has CMOS-compatible input thresholds. The 'ACT16862 has TTL-compatible input thresholds.

The 54AC16862 and 54ACT16862 are characterized over the full military temperature range of -55°C to 125°C. The 74AC16862 and 74ACT16862 are characterized for operation from -40°C to 85°C.
