Housed in a 20-pin DIP (0.300\" body) for through-hole assembly, it suits legacy backplanes, industrial control panels, and prototyping where socketed or hand-solderable logic is preferred. No derating is needed for the full military temp band, but junction temperature still governs long-term reliability at the upper end. ## Output drive and 3-state control Each of the eight I/O lines can sink or source 24 mA (both high and low), enough to drive a standard TTL load, a logic input fan-out of ten, or a small LED through a series resistor. The 3-state outputs let multiple transceivers share a common data bus without contention — the output-enable pin disables all drivers, placing the outputs in high-impedance. This is the standard bus-interface pattern for backplanes and memory-mapped I/O. ## Lifecycle and compliance No PCN or LTB has been issued for this specific order code as of the latest available data.","metaTitle":"CD74AC623E 74AC Transceiver, Non-Inverting, 3-State, 20-DIP","metaDescription":"CD74AC623E 8-bit non-inverting transceiver with 3-state outputs. 1.5V to 5.5V supply, -55°C to 125°C range, 24 mA drive.
