8-bit registered bus transceiver featuring true outputs and bidirectional data flow. This logic IC operates with a supply voltage range of 2V to 6V, supporting a nominal 4.5V. Designed for MILITARY temperature grade applications, it functions between -55°C and 125°C. The component utilizes positive edge triggering and independent control for its two ports, with a propagation delay of 325ns. Housed in a 24-terminal PDIP package (R-PDIP-T24), it offers a 24-pin configuration.
