Six Schmitt-trigger inverters in a 14-pin DIP
The Texas Instruments SN74AC14N packs six independent inverter gates, each with Schmitt-trigger input hysteresis, into a through-hole 14-pin DIP. It runs on a 2V to 6V supply rail and delivers 24mA sink and source per output. The 74AC family is faster than the older 74HC series — propagation delay is 10ns at 5V with a 50pF load, which gives you more timing margin on a legacy bus that's being pushed harder.
Through-hole DIP — still the right call for repair and prototyping
The 14-pin DIP (0.300" body width) is a socket-friendly footprint. If you're reworking a legacy control board or breadboarding a circuit, this package saves you from hot-air rework. The 24mA output drive is enough to light an LED directly or drive a few TTL loads without a buffer. Mounting is through-hole only — no SMT variant of this exact order code.
Lifecycle and compliance — no surprises
No last-time-buy notice, no NRND flag. It's ROHS3 compliant, so it passes the EU material restrictions for new builds. If you're qualifying a BOM for a five-year production run, this part isn't going to vanish mid-cycle.
