Product details
Overview
74HCT1G14GW,165 from Nexperia is a single-channel CMOS inverting Schmitt trigger with TTL-compatible input thresholds, 5-pin TSSOP5 (SOT353-1) package, operating from 4.5 V to 5.5 V supply, delivering 2.0 V hysteresis at VCC = 5.5 V and propagation delay of 17 ns (typ) at CL = 50 pF - used for noise-immune signal conditioning in microcontroller reset circuits and sensor interface front-ends.
For engineers reviewing the 74HCT1G14GW,165 datasheet, 74HCT1G14GW,165 pinout, 74HCT1G14GW,165 application, or 74HCT1G14GW,165 equivalent, key selection criteria include TTL-level input compatibility, guaranteed hysteresis >0.4 V across temperature, -40 °C to +125 °C operation, and low ICC (<20 μA at VCC = 5.5 V), critical for robust edge detection in industrial control and automotive body electronics.
Technical Context
This device implements a single inverter stage with Schmitt-trigger input architecture, enabling clean digital output transitions from slow-rising or noisy analog-like inputs. Its input clamping diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
The TTL-compatible input threshold (VT+ = 1.4 V, VT− = 0.6 V at VCC = 5.5 V) ensures reliable logic-level translation from legacy 5 V systems, while symmetrical output drive (±2.0 mA) supports direct connection to downstream CMOS loads without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V rail and tolerant of ±5% regulation drift |
| Input Threshold (VT+) | 1.4 V (min) at VCC = 5.5 V - ensures reliable HIGH detection from TTL sources |
| Hysteresis (VH) | 0.4 V (min) at VCC = 5.5 V - rejects up to 400 mV of input noise without false triggering |
| Propagation Delay | 17 ns (typ) at VCC = 4.5 V, CL = 50 pF - enables stable timing in sub-30 MHz waveform shaping |
| Output Drive | ±2.0 mA - sufficient to directly drive multiple 74-series inputs or small capacitive loads ≤50 pF |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood and industrial motor-control environments |
| ESD Protection | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events per JEDEC JS-001/JS-002 |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package, 5-lead, 1.25 mm body width, 0.65 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - must be left unconnected; no routing or grounding required |
| 2 | A | Inverting Schmitt trigger input - accepts TTL-level signals; clamping diodes enable overvoltage tolerance |
| 3 | GND | Digital ground reference - requires low-impedance local decoupling to minimize switching noise coupling |
| 4 | Y | Inverted, jitter-free output - provides sharp edges even with input rise/fall times >1 μs |
| 5 | VCC | Positive supply - must be bypassed with 100 nF ceramic capacitor placed within 3 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input levels | Enables direct interfacing with legacy 5 V microcontrollers and logic families without level-shifting |
| Guaranteed hysteresis ≥0.4 V | Rejects high-frequency noise and contact bounce in switch debouncing applications |
| Symmetrical output impedance | Ensures matched rise/fall times and consistent timing margins in clockless edge-sensitive circuits |
| Unlimited input rise/fall times | Accepts arbitrarily slow input transitions (e.g., thermistor-based thresholds) without metastability |
| CMOS low power dissipation | ICC < 20 μA at VCC = 5.5 V enables use in always-on sensor wake-up paths with minimal quiescent load |
Applications
| Switch Debouncing | Waveform Shaping |
|---|---|
|
Use Scenario: Mechanical push-button or rotary encoder connected to a microcontroller GPIO requiring clean digital edges. IC Role / Device Role: Inverting Schmitt trigger providing hysteresis-based noise rejection on the raw switch signal before MCU sampling. Use Value: Eliminates software debounce routines, reduces firmware complexity, and guarantees deterministic 1-shot detection per actuation. |
Use Scenario: Analog sensor output (e.g., thermistor divider) with slow ramping voltage feeding into a digital comparator or timer input. IC Role / Device Role: Signal conditioner converting gradual analog transitions into clean square-wave logic outputs. Use Value: Enables precise zero-crossing or threshold detection without external op-amps or comparators, saving board space and BOM cost. |
| Oscillator Core | Reset Signal Conditioning |
|
Use Scenario: RC relaxation oscillator generating clock or timing pulses for low-cost timing functions. IC Role / Device Role: Active element in a 2-component oscillator (with R and C), leveraging internal hysteresis to define frequency. Use Value: Provides stable, temperature-compensated oscillation (K-factor ~0.8 at VCC = 5.5 V) without crystals or dedicated timer ICs. |
Use Scenario: Power-on reset circuit where brown-out detection must tolerate supply ripple and startup transients. IC Role / Device Role: Input filter for reset generator IC or microcontroller reset pin, rejecting short-duration supply glitches. Use Value: Prevents spurious resets during 12 V battery cranking or DC-DC converter soft-start phases in automotive ECUs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar inverting Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G14DBVR | Wider VCC range (1.65–5.5 V); CMOS input thresholds; lower hysteresis (0.25 V typ at 3.3 V) | Better suited for mixed-voltage 3.3 V/5 V systems; less noise margin than 74HCT1G14GW,165 at 5 V | Select when operating below 4.5 V or integrating with LVC-family logic |
| MC74VHC1G14DTT1G | Higher speed (tpd = 9.5 ns typ at VCC = 5 V); tighter hysteresis control (0.35–0.55 V); same pinout | Preferred for high-frequency waveform generation (>10 MHz) where propagation delay consistency matters | Select when sub-10 ns delay and tighter VH tolerance are required in timing-critical paths |
Compared with SN74LVC1G14DBVR and MC74VHC1G14DTT1G, the 74HCT1G14GW,165 offers superior noise immunity at 5 V due to its larger, guaranteed hysteresis and TTL-input compatibility - making it optimal for legacy 5 V industrial interfaces where signal integrity trumps raw speed.

FAQ
What is the maximum recommended supply voltage for 74HCT1G14GW,165?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V per JEDEC JESD8C compliance. Operation above 5.5 V voids parametric guarantees and risks accelerated aging due to increased ICC and junction temperature.
Can Pin 1 (n.c.) be grounded or tied to VCC?
No - Pin 1 is internally unconnected and must remain floating. Connecting it to any potential may induce parasitic coupling or violate package stress limits; Nexperia's datasheet explicitly prohibits termination of this pin.
How does the 74HCT1G14GW,165 differ from the 74HC1G14GW variant?
The 74HCT1G14GW uses TTL-compatible input thresholds (VIH ≈ 2.0 V, VIL ≈ 0.8 V), while the 74HC1G14GW uses CMOS thresholds (VIH/VIL ≈ 0.5 × VCC). This makes the HCT version interoperable with legacy 5 V TTL outputs without level shifters, unlike the HC version.
Is thermal derating required for continuous operation at +125 °C?
Yes - total power dissipation must be linearly derated above +74 °C at 3.3 mW/K for the TSSOP5 package. At +125 °C, maximum allowed Ptot drops to approximately 85 mW (250 mW − 3.3 × (125 − 74)), requiring careful layout and ambient thermal management.
