Quad NAND gate with Schmitt-trigger inputs — what it is and where it fits
The Texas Instruments SN74AHCT132D is a quad 2-input NAND gate from the 74AHCT family with Schmitt-trigger inputs. It operates from a 4.5 V to 5.5 V supply and is rated from -40°C to 85°C.
9 ns propagation delay — timing budget for a 5 V bus
With a maximum propagation delay of 9 ns at 5 V into a 50 pF load, the SN74AHCT132D is fast enough to sit between a 50 MHz microcontroller and a peripheral without adding a full clock cycle of latency. The 8 mA output drive is enough to switch a handful of CMOS inputs or a short ribbon cable, but if you're driving a long trace or a high fan-out, you'll want to buffer it. The quiescent current maxes out at 2 µA, so it won't eat into your standby budget.
Active and RoHS3 — no supply-chain surprises
The SN74AHCT132D carries an Active lifecycle status and is ROHS3 compliant. There's no end-of-life notice, no last-time-buy pressure, and no lead-free exemption to track. It's a standard catalog part that you can qualify into a production BOM without worrying about a sudden discontinuation.
14-SOIC footprint — board-level fit
Housed in a 14-SOIC package (0.154" body width, 3.90 mm) with a surface-mount footprint, this part is a drop-in for any standard SOIC-14 land pattern. The supplier device package is listed as 14-SOIC. No special handling beyond normal MSL precautions — it's a standard logic gate, not a moisture-sensitive BGA.
