5962-9173801MRA

Product Overview

5962-9173801MRA is a military-qualified 8-bit transparent D-type latch with 3-state outputs, corresponding to the National Semiconductor 54F573DMQB and compatible qualified-source equivalents. The device integrates eight transparent latches with a common latch-enable input and a common output-enable input, allowing temporary storage and controlled connection to system buses. Built using FAST TTL logic and supplied in a hermetic 20-pin ceramic DIP package, it is specified for operation across the -55°C to +125°C military temperature range. The device is suitable for avionics, defense electronics, processor interfaces, bus buffering and other high-reliability digital systems.
