This 4-bit bidirectional bus transceiver, operating from a 4.5V to 5.5V supply, features true outputs and independent control. Designed for military temperature grades (-55°C to 125°C), it offers a propagation delay of 8.5ns at nominal supply voltage. The component is housed in a 20-terminal ceramic CQCC package with a JEDEC code of S-CQCC-N20, measuring 8.89mm in width and length. It supports a maximum output current (Iol) of 48mA and a load capacitance of 50pF.
