NXP Semiconductors 74HCT10PW,112

Overview

74HCT10PW,112 from Nexperia is a triple 3-input NAND gate in TSSOP14 package, designed for TTL-level input compatibility (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), with propagation delay of 24 ns (max) at VCC = 4.5 V and CL = 50 pF, operating across -40 °C to +125 °C. It serves as a logic combinatorial building block in industrial control sequencers, digital instrumentation front-ends, and programmable logic interface layers.

For engineers reviewing the 74HCT10PW,112 datasheet, 74HCT10PW,112 pinout, 74HCT10PW,112 application, or 74HCT10PW,112 equivalent, key selection criteria include TTL-compatible input thresholds, guaranteed 125 °C operation, TSSOP14 thermal performance (7.3 mW/K derating above 81 °C), and triple-gate integration for compact combinational logic implementation.

Technical Context

The 74HCT10PW,112 implements three independent 3-input NAND gates using silicon-gate CMOS technology with TTL-compatible input circuitry-ensuring direct replacement for legacy 74LS logic without level-shifting. Each gate exhibits identical truth table behavior: output LOW only when all three inputs are HIGH.

Its input clamping diodes support interfacing to voltages exceeding VCC when used with current-limiting resistors, and its static characteristics guarantee VIH ≥ 2.0 V and VIL ≤ 0.8 V over full temperature and supply range-critical for robust noise margin in mixed-voltage systems.

FAQ

Is 74HCT10PW,112 pin-compatible with 74HC10PW?

Yes-both share identical TSSOP14 pinout (SOT402-1) and logic function. However, 74HCT10PW uses TTL-compatible input thresholds (VIH ≥ 2.0 V), while 74HC10PW requires CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V). Swapping them may cause logic misreads unless input voltage levels are verified.

What is the maximum recommended operating frequency for 74HCT10PW,112?

While not a clocked device, its 24 ns max propagation delay at VCC = 4.5 V and CL = 50 pF supports reliable operation in combinational logic paths with ≤20 MHz toggle rates. For synchronous systems, ensure setup/hold margins exceed tpd + trace delays, especially at temperature extremes.

Does 74HCT10PW,112 require external pull-up or pull-down resistors on unused inputs?

Yes-unused inputs must be tied to VCC or GND. Floating CMOS inputs cause increased supply current, unpredictable logic states, and potential device overheating. Each unconnected input draws up to 735 μA (ΔICC) at VCC = 5.5 V, degrading noise immunity and power efficiency.

Can 74HCT10PW,112 drive a 50 pF load at 5 V while maintaining full-spec timing?

Yes-the datasheet specifies tpd and tt values explicitly at CL = 50 pF and VCC = 4.5 V. At 5.0 V, propagation delay improves to 11 ns (typical), confirming full compliance with timing specs under these conditions. Output drive capability remains ±4.0 mA, sufficient for this load.
