The SN74HC10D is a triple 3-input NAND gate from the 74HC family, in a 14-SOIC package. It operates from 2V to 6V supply, making it a drop-in for 3.3V or 5V digital logic buses in mixed-voltage boards. Each of the three gates sinks or sources 5.2 mA at the output, enough to drive a single standard CMOS load or a low-power LED indicator without a buffer.
Timing and supply margins for BOM fit
Maximum propagation delay is 16 ns at 6V with a 50 pF load. The 74LVC10AD has a 4.7 ns delay at 3.3V. Input logic thresholds are 0.5V to 1.8V for low and 1.5V to 4.2V for high, which means the gate reliably interprets 3.3V CMOS levels but may not cleanly read 1.8V logic without a level shifter. Quiescent current maxes at 2 µA, negligible for battery-powered or always-on subsystems where every microamp counts.
Lifecycle and sourcing posture
Production is current. ROHS3 compliant and lead-free.
