Product details

Quad NAND with Schmitt-trigger inputs — 5V workhorse for noisy environments

33 ns propagation delay — timing budget for legacy 5V buses

At 4.5V and 50 pF load the part delivers 33 ns max propagation delay. That is slower than a 74LVC or 74AUC gate, but it is within the timing margin for 5V backplanes. Quiescent current maxes at 2 µA, so the power footprint is negligible even with four gates switching. Output drive is 4 mA sink and source — enough to drive one or two standard 74HCT loads, not a long backplane trace.

Sourcing: active, no LTB risk, available through independent channels

Frequently asked questions

What is the difference between the CD74HCT132M and the 74HC132?

The 74HCT series is designed for TTL-compatible input thresholds (1.9V to 2.1V high), while the 74HC series uses CMOS thresholds (typically 3.15V high at 5V supply). If your driving stage is a TTL output, the HCT version ensures correct logic-level detection. The CD74HCT132M also carries the full -55°C to 125°C temperature range.
