Product details

Logic function and BOM fit

The SN74S65N is an AND-OR-INVERT gate from the 74S Schottky TTL family, a logic function that combines two AND terms into a single NOR output. In a legacy TTL backplane or control board, this gate replaces a discrete AND-OR-INVERT network with one DIP package, saving board area and reducing propagation delay through the logic path.

Production status and compliance

The part is RoHS non-compliant, which is typical for older SnPb-plated DIP packages — factor this into BOM compliance if your assembly line requires RoHS exemption or a waiver.

Frequently asked questions

Is SN74S65N equivalent to SN74S40N?

The SN74S40N is a peer dual 4-input NAND gate in the same 74S family, not a direct functional equivalent — the SN74S65N implements AND-OR-INVERT logic, while the SN74S40N is a NAND function. For a same-function second-source, verify the logic equation matches your design; the SN74S40N may serve as a substitute if the AND-OR-INVERT is implemented externally.
