The 3-state outputs let multiple devices share a common data bus without contention — the outputs go high-impedance when the output-enable pin is deasserted, which is the standard way to build a bidirectional bus on a 5V backplane. Supply range is 4.5V to 5.5V, which covers the full 5V ±10% tolerance window used in most industrial logic and memory interfaces. The -40°C to 125°C operating temperature range qualifies it for under-hood automotive or factory-floor environments where the ambient inside the enclosure can hit 105°C. ## Output drive and bus loading Each output sources or sinks 8 mA (both high and low), which is typical for the 74AHCT family. This drive level is enough to fan out to ten 74LS-type loads or drive a short backplane trace up to about 30 pF at the rated speed. For longer traces or higher capacitive loads, the 32 mA drive of the 74ABT2245 peer would be a better fit. The 0.025-inch lead pitch requires a PCB with fine-pitch soldering capability but is well within the range of most assembly houses. The reel packaging (Tape & Reel) is the standard for automated pick-and-place — the cut-tape option is available for prototype builds. ## Lifecycle and compliance The part is ROHS3 compliant, which means it meets the current EU RoHS exemption limits for lead in solder joints and other restricted substances.","metaTitle":"SN74AHCT16245DLR Texas Instruments 74AHCT Transceiver","metaDescription":"Texas Instruments SN74AHCT16245DLR 74AHCT 16-bit transceiver, 4.5-5.5V, 8mA output, -40 to 125°C, 48-SSOP.
