Dual 4-bit bus driver with inverted outputs, featuring a 9ns propagation delay at nominal supply voltage. This logic IC operates within a -55°C to 125°C temperature range and supports a supply voltage of 4.5V to 5.5V. Housed in a 20-terminal ceramic CQCC package, it offers two independent 4-bit driver functions with an enable-low control. Designed for military temperature grades and MIL-STD-883B screening, it boasts a maximum output current of 48mA.
