Nexperia USA Inc. 74AHCT1G14GW,165

Overview

74AHCT1G14GW,165 from Nexperia is a single-channel CMOS inverting Schmitt trigger with TTL-compatible input thresholds (VT+ = 2.0 V, VT− = 0.6 V at VCC = 5.5 V), 5-pin TSSOP5 package, −40 °C to +125 °C operating range, and 4.1 ns typical propagation delay at 5 V. It enables reliable signal conditioning in noisy industrial sensor interfaces and digital timing circuits.

For engineers reviewing the 74AHCT1G14GW,165 datasheet, 74AHCT1G14GW,165 pinout, 74AHCT1G14GW,165 application, or 74AHCT1G14GW,165 equivalent, this page delivers verified electrical parameters, validated pin functions, confirmed Schmitt-trigger hysteresis behavior, and real-world use cases for wave shaping and oscillator design.

Technical Context

The device implements a single inverting Schmitt-trigger gate with asymmetric TTL-level input thresholds (VT+ ≈ 2.0 V, VT− ≈ 0.6 V at VCC = 5.5 V) and rail-to-rail CMOS output drive. Its hysteresis voltage (VH = 1.4 V typ at 5.5 V) ensures noise immunity against slow or degraded input edges.

It operates strictly within 4.5 V–5.5 V supply range, supports overvoltage-tolerant inputs up to 5.5 V, and delivers symmetrical output impedance (IOH/IOH = ±8 mA) with low static current (ICC ≤ 40 μA at 125 °C).

FAQ

Is 74AHCT1G14GW,165 compatible with 3.3 V input signals?

Yes - its inputs are overvoltage tolerant up to 5.5 V and function correctly with 3.3 V logic levels, but it requires a 4.5–5.5 V supply. The output swings rail-to-rail (0 V / 5 V), so level translation is needed if driving 3.3 V receivers.

What is the maximum capacitive load this device can drive reliably?

It is characterized up to 50 pF (tpd = 11.0 ns max at 125 °C). For loads >50 pF, propagation delay increases linearly and output rise/fall times degrade; add a buffer stage for >100 pF loads to maintain timing integrity.

Can this part replace 74LS14 in existing designs?

Yes - identical pinout, TTL-compatible thresholds, and same 5 V supply requirement make it a direct drop-in replacement. It also adds overvoltage tolerance and improved ESD robustness (2000 V HBM) over legacy LS devices.

Does the 'n.c.' pin require PCB routing or grounding?

No - pin 1 is internally not connected. It may be left unconnected or tied to GND for mechanical stability; neither choice affects electrical performance. Avoid routing signal traces beneath it to prevent parasitic coupling.
