Octal Bus Transceiver, featuring 8 bidirectional channels with 3-state outputs. This CMOS logic IC operates with a supply voltage range of 2V to 6V, typically 5V, and supports a maximum output current of 7.8mA (high) and 6mA (low). Designed for surface mounting in a 20-SOIC package, it offers a propagation delay of 22ns and a turn-on delay time of 335ns. The device functions as an inverting transceiver, suitable for operation across a temperature range of -40°C to 85°C.
