Octal Bus Transceiver, featuring 8 bidirectional, 3-state outputs. This surface-mount device operates with a 5V supply voltage, accepting 4.5V to 5.5V, and delivers 48mA high-level and 24mA low-level output current. With a propagation delay of 10ns and turn-on delay of 20ns, it supports 8 channels and is packaged in a 20-SO (SOP) format on tape and reel. The transceiver logic function is inverting, with a non-inverting polarity, and it operates within a temperature range of 0°C to 70°C.
