What the 1.5 V–5.5 V supply and –55°C to 125°C range mean for your BOM
The CD74AC245M96 is an 8-bit non-inverting transceiver with 3-state outputs from the 74AC family, packaged in a 20-SOIC (7.50 mm width) for surface-mount assembly. Its supply range from 1.5 V to 5.5 V lets it bridge 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without an external level shifter — useful when a mixed-voltage backplane carries both a 3.3 V controller and 5 V peripherals. The military-temperature rating (–55°C to 125°C) covers avionics, satellite, and downhole instrumentation where the ambient can swing from a cold soak to a hot engine bay; the 24 mA sink and source drive is enough to fan out to eight standard LSTTL loads or drive a short ribbon cable directly.
Active lifecycle — no LTB clock ticking
The CD74AC245M96 carries an Active product status and is ROHS3 compliant. For a production line that already qualifies the 20-SOIC footprint, this part does not force an immediate requalification cycle.
24 mA output drive — signal-integrity budget on a loaded bus
The 24 mA output current at both high and low levels determines how many receiver inputs the transceiver can drive before the edge rate degrades. In a 5 V system with 50 pF per node, 24 mA keeps the rise time under 5 ns across four or five loads; at 1.5 V the drive scales with the supply but still handles point-to-point links. The 3-state outputs let multiple transceivers share the same bus without contention — the DIR and OE pins control direction and bus isolation.
