The tape-and-reel option (TR) suits automated pick-and-place assembly; cut-tape (CT) is also available for prototyping. No thermal pad — standard TSSOP land pattern applies.

ROHS3 compliant.

Frequently asked questions

What is the difference between SN74AHC245 and SN74AHCT245?

The SN74AHCT245 is a TTL-compatible version of the same function. It has tighter input thresholds (0.8 V / 2.0 V) for interfacing with TTL logic, while the AHC variant uses CMOS thresholds (0.9 V / 3.15 V at 5 V). Supply range and drive are similar.

Can SN74AHC245PWR be used at 3.3 V?

Yes. The supply range is 2 V to 5.5 V, so 3.3 V is well within the operating window. Propagation delay will be slightly higher than at 5 V, but the part is fully characterised at 3.3 V.
