Product details
Overview
74HC14D,652 from Nexperia is a hex inverting Schmitt trigger IC with TTL-compatible input thresholds, 2.0–6.0 V supply range, ±25 mA output drive, -40 °C to +125 °C operating temperature, and SO14 (SOT108-1) package. It converts slow-rising/noisy signals into clean digital outputs and is used in waveform shaping and relaxation oscillator circuits.
For engineers reviewing the 74HC14D,652 datasheet, 74HC14D,652 pinout, 74HC14D,652 application, or 74HC14D,652 equivalent, key selection criteria include Schmitt-trigger hysteresis voltage (min 0.6 V at VCC = 6.0 V), propagation delay (12–125 ns depending on VCC and load), input clamp diode support for overvoltage tolerance, and guaranteed operation across industrial and extended temperature ranges.
Technical Context
This device implements six independent CMOS inverter stages, each with asymmetric Schmitt-trigger input thresholds (VT+ and VT−) enabling noise-immune signal conditioning. Its input clamping diodes allow safe interfacing to voltages exceeding VCC when current-limiting resistors are used.
The logic function is strictly inverting (L→H, H→L), with hysteresis defined as VH = VT+ − VT− (0.6–1.6 V typical at VCC = 6.0 V). Dynamic performance is characterized under CL = 50 pF loads, with propagation delays specified per supply voltage and temperature grade.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports dual-supply systems and direct interface with 3.3 V and 5 V logic families |
| Operating Temperature | -40 °C to +125 °C - qualified for extended industrial and under-hood applications |
| Output Drive | ±25 mA - sufficient to directly drive LEDs, small relays, or fan-out to ≥10 standard CMOS inputs |
| Hysteresis Voltage (VH) | 0.6 V (min) at VCC = 6.0 V - provides robust noise margin against EMI-induced glitches on slow edges |
| Propagation Delay (tpd) | 12 ns (typ) at VCC = 6.0 V, CL = 50 pF - enables reliable timing in oscillator and pulse-shaping circuits up to ~30 MHz |
| Input Clamp Current | ±20 mA - permits safe overvoltage input handling (VI < -0.5 V or > VCC + 0.5 V) with external series resistors |
| Power Dissipation (Ptot) | 500 mW (max) - derates linearly above 100 °C for SO14 package (10.1 mW/K), limiting thermal design headroom |
Pinout & Package
74HC14D,652 is housed in a plastic small outline package (SO14, SOT108-1) with 14 leads, 3.9 mm body width, and gull-wing lead form. Pin 1 is marked by a notch or index area; the package is RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 3A, 5A, 9A, 11A, 13A | Schmitt-trigger input | Six independent logic inputs; each features hysteresis and input clamp diodes for overvoltage resilience |
| 2Y, 4Y, 6Y, 8Y, 10Y, 12Y | Inverted output | Six complementary outputs; each sinks or sources up to ±25 mA with rail-to-rail swing |
| 7 | GND | Primary ground reference for all internal circuitry and I/O; must be low-impedance for noise immunity |
| 14 | VCC | Positive supply rail; decoupling capacitor (100 nF ceramic) required within 10 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 2.0–6.0 V operation enables drop-in use in both 3.3 V and 5 V systems without level shifters |
| TTL-compatible inputs | Input thresholds match TTL logic levels (VT+ ≈ 1.7–4.4 V at VCC = 4.5 V), simplifying mixed-logic interfacing |
| Unlimited input edge rates | No minimum rise/fall time requirement - accepts arbitrarily slow transitions without metastability or oscillation |
| ESD robustness | HBM > 2000 V and CDM > 1000 V - reduces risk of field failure during handling and PCB assembly |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up under transient overvoltage conditions |
Applications
| Waveform Shaping | Astable Multivibrator |
|---|---|
|
Use Scenario: Converting noisy or slowly varying analog sensor outputs (e.g., thermistor-based temperature monitoring) into clean square-wave signals for microcontroller GPIO capture. IC Role / Device Role / Timing Role: Signal conditioner and digital threshold translator - transforms analog edge ambiguity into deterministic logic-level transitions. Use Value: Eliminates software debouncing overhead and prevents false interrupts caused by EMI or contact bounce in industrial control panels. |
Use Scenario: Generating fixed-frequency clock signals for LED flashers, status indicators, or low-speed data strobes in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Core oscillator element - two cascaded inverters plus RC network establish stable free-running oscillation. Use Value: Requires only two external passive components (R, C); frequency stability is improved by Schmitt-trigger hysteresis versus standard inverters. |
| Monostable Multivibrator | Pulse Edge Detection |
|
Use Scenario: Creating precise one-shot pulses (e.g., 10–100 ms width) to trigger reset sequences or enable power rails in embedded power management subsystems. IC Role / Device Role / Timing Role: Timing generator - single inverter stage with RC feedback sets pulse duration via exponential charge/discharge. Use Value: Provides predictable, jitter-free pulse widths independent of input signal slew rate - critical for synchronous system initialization. |
Use Scenario: Detecting rising or falling edges of mechanical switch closures (e.g., pushbutton interfaces) in medical device front panels where contact bounce exceeds 10 ms. IC Role / Device Role / Timing Role: Glitch filter and edge squarer - rejects sub-millisecond transients while preserving intentional state changes. Use Value: Reduces firmware complexity by delivering clean, bounce-free logic edges directly to interrupt-capable MCU pins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverting Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT14D,652 | CMOS input thresholds shifted to 1.2–1.9 V (VT+) for strict TTL compatibility; identical SO14 package and pinout | Better suited for legacy 5 V TTL systems with marginal noise margins; slightly higher ICC at VCC = 5.5 V | Select when interfacing exclusively with 5 V TTL outputs and requiring guaranteed recognition of 2.0 V logic-high inputs |
| SN74LV14APWR | Lower VCC range (1.65–5.5 V); 32 mA output drive; LVC-family propagation delay (5.5 ns typ at 3.3 V) | Optimized for modern 1.8/2.5/3.3 V systems; not rated for 6 V operation or -40 °C to +125 °C full range | Choose for high-speed, low-voltage designs where 6 V tolerance and extended temperature are not required |
Compared with 74HC14D,652, the 74HCT14D,652 offers tighter input threshold alignment with legacy TTL but sacrifices 6 V operation; SN74LV14APWR delivers faster switching at lower voltages but lacks extended temperature and overvoltage resilience.

FAQ
Can 74HC14D,652 operate reliably at 2.0 V supply?
Yes - it is fully specified down to 2.0 V supply voltage with guaranteed propagation delay (125 ns max), hysteresis (≥0.2 V), and output drive (±4.0 mA) across -40 °C to +125 °C. Input thresholds scale proportionally with VCC, maintaining functional hysteresis even at minimum voltage.
What is the maximum capacitive load it can drive without signal degradation?
The datasheet specifies dynamic characteristics up to CL = 50 pF. Driving loads beyond 50 pF increases propagation delay and transition time - e.g., at CL = 100 pF and VCC = 6.0 V, tpd rises to ~35 ns and tt to ~25 ns. For heavier loads, buffer stages or lower-impedance drivers are recommended.
Does it support mixed-voltage interfacing, such as 3.3 V inputs with 5 V supply?
Yes - input clamp diodes allow safe interface to voltages up to VCC + 0.5 V when series current-limiting resistors are used. With VCC = 5 V, a 3.3 V input is well within the safe VI range (0–5.5 V), and the Schmitt-trigger thresholds (≈1.7–3.15 V) ensure reliable recognition.
Is the SO14 package lead-free and RoHS-compliant?
Yes - the 74HC14D,652 in SOT108-1 package is manufactured per Nexperia's standard RoHS-compliant, lead-free process. The finish is matte tin, and the package meets JEDEC J-STD-020 moisture sensitivity level MSL3 (260 °C reflow peak).
