SN74ALS29863DWE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS29863DWE4 is a 9-bit bus transceiver designed for asynchronous two-way communication between data buses. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to 70°C. The device features four independent output-enable inputs (OEAB1, OEAB2, OEBA1, OEBA2) that control data flow direction or isolation. Electrical characteristics include a high-level output current of -24 mA and a low-level output current of 48 mA at VCC = 4.75 V. Propagation delays are specified as 8 ns maximum with a 50 pF load and 15 ns maximum with a 300 pF load.
