Product details

The 74AC16640DL is a 16-bit bus transceiver from the 74AC logic family, designed for bidirectional data flow between two independent buses. The 74AC series operates on a standard supply rail, offering higher speed than the original 74HC family while maintaining CMOS-level input thresholds.

Active lifecycle — no LTB risk

Note the RoHS non-compliant status — this part uses lead-bearing solder finishes. If your assembly line is RoHS-exempt (military, aerospace, high-reliability industrial) or you have a waiver, that is fine. For a standard lead-free reflow profile, you will need to qualify a Pb-free alternative or accept the process deviation.

Frequently asked questions

Can 74AC16640DL be used as a replacement for 74ACT16640?

The 74AC16640DL and 74ACT16640 are functionally similar 16-bit bus transceivers, but the ACT variant uses TTL-compatible input thresholds while the AC variant uses CMOS thresholds. If your driving logic is 5 V TTL, the AC part may not recognize a valid high at the minimum TTL VIH level. Verify input voltage compatibility before substituting.
