Nexperia USA Inc. 74HC1G14GW,165

Overview

74HC1G14GW,165 from Nexperia is a single-channel CMOS inverting Schmitt trigger logic gate in TSSOP5 (SOT353-1) package, operating from 2.0 V to 6.0 V supply, with ±12.5 mA output drive, 26 ns max propagation delay at 6.0 V/50 pF, and -40 °C to +125 °C temperature range - used for noise-immune signal conditioning in sensor interface and oscillator circuits.

For engineers reviewing the 74HC1G14GW,165 datasheet, 74HC1G14GW,165 pinout, 74HC1G14GW,165 application, or 74HC1G14GW,165 equivalent, this page delivers verified pin functions, Schmitt-trigger hysteresis values (0.6–1.6 V), input threshold voltages (VT+ = 2.1–4.2 V at VCC = 6.0 V), static/dynamic electrical specs, and real-world use cases in waveform shaping and relaxation oscillators.

Technical Context

The 74HC1G14GW,165 implements a single inverter with hysteresis via internal positive feedback, enabling clean digital transitions from slow-rising analog inputs. Its Schmitt-trigger input has asymmetric thresholds (VT+ and VT−) defined per supply voltage: at VCC = 6.0 V, VT+ = 2.1–4.2 V and VT− = 1.2–2.6 V, yielding 0.6–1.6 V hysteresis (VH).

It features clamp diodes on all inputs, allowing safe interfacing to signals exceeding VCC when current-limiting resistors are used. The device supports unlimited input rise/fall times and delivers symmetrical output impedance with balanced tPLH/tPHL propagation delays - critical for jitter-free clock edge generation in monostable and astable multivibrator topologies.

FAQ

What is the maximum recommended supply voltage for continuous operation?

The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V per JEDEC JESD7A. Operation above 6.0 V risks exceeding internal oxide breakdown limits and invalidates parametric guarantees - sustained use at 6.5 V is not advised even if below the 7.0 V limit.

Can Pin 1 (n.c.) be tied to GND or left floating on the PCB?

Pin 1 is internally unconnected and must remain unbonded and unconnected on the PCB. Neither grounding nor floating introduces functional risk, but best practice is to leave it unpopulated and untracked to avoid accidental shorting or parasitic coupling in high-density layouts.

How does input hysteresis improve performance in noisy environments?

Hysteresis creates distinct VT+ (rising) and VT− (falling) thresholds - e.g., 4.4 V and 3.7 V at VCC = 4.5 V - so noise spikes smaller than 0.7 V cannot cause unintended output toggling. This eliminates chatter on slow-rising signals like those from thermistors or long cables exposed to EMI.

Is the 74HC1G14GW,165 suitable for driving capacitive loads above 50 pF?

Yes, but with timing impact: propagation delay increases linearly with load capacitance. At CL = 100 pF and VCC = 6.0 V, tpd rises to ~45 ns (vs. 26 ns at 50 pF). For loads >100 pF, add series resistance to limit peak current and prevent ground bounce.
