Product details
Overview
74HC7014D,112 from Nexperia is a hex non-inverting precision Schmitt-trigger buffer IC with six independent channels, designed for signal conditioning in electrically noisy environments. It features precisely defined hysteresis (160–240 mV at VCC = 6.0 V), operates from 2.0 V to 6.0 V, and supports industrial temperature range up to +125 °C. Its inputs tolerate −1.5 V to +16 V and include clamp diodes for overvoltage-safe interfacing.
For engineers reviewing the 74HC7014D,112 datasheet, 74HC7014D,112 pinout, 74HC7014D,112 application, or 74HC7014D,112 equivalent, key selection criteria include input hysteresis voltage window (0.55×VCC to 0.65×VCC), propagation delay (27–112 ns depending on VCC), SO14 package compatibility, and ESD robustness (HBM >2000 V, CDM >1000 V).
Technical Context
The 74HC7014D implements six identical CMOS Schmitt-trigger buffers, each with independently defined positive-going (VT+) and negative-going (VT−) thresholds-ensuring clean digital output from slow or noisy analog inputs. Thresholds are tightly specified across VCC (2.0–6.0 V) and temperature (−40 °C to +125 °C), with hysteresis (VH) ranging from 50 mV to 240 mV.
Each channel provides rail-to-rail output swing, ±20 mA clamping current capability, and unlimited input rise/fall times. The device uses standard HC logic levels but adds precision hysteresis-enabling reliable waveform shaping without external components in applications like encoder signal debouncing or sensor interface conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - Enables direct interface with 3.3 V and 5 V logic systems without level shifters. |
| Input Hysteresis (VH) | 160–240 mV at VCC = 6.0 V - Provides noise margin against glitches up to ±120 mV around threshold crossing. |
| Propagation Delay (tPHL/tPLH) | 27–112 ns (VCC = 6.0 V to 3.0 V) - Ensures deterministic timing for edge-sensitive circuits like clock recovery or pulse synchronization. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Allows safe handling and board-level integration without additional protection circuitry. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive subsystems and industrial control enclosures. |
| Input Overvoltage Tolerance | −1.5 V to +16 V - Permits direct connection to sensors or switches operating beyond VCC without external resistors or clamps. |
| Output Drive Strength | ±4.0 mA at VCC = 4.5 V - Sufficient to drive multiple 74HC inputs or small capacitive loads (<50 pF) directly. |
Pinout & Package
74HC7014D,112 is housed in a 14-lead SO14 (SOT108-1) plastic small outline package with 3.9 mm body width, 1.27 mm lead pitch, and gull-wing surface-mount terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (1A–6A) | Six independent Schmitt-trigger inputs; each accepts slow-rising/falling signals and rejects noise within hysteresis window. |
| 2, 4, 6, 8, 10, 12 | Output (1Y–6Y) | Non-inverting buffered outputs; rail-to-rail swing with typical VOH = 5.48 V / VOL = 0.16 V at VCC = 6.0 V, IO = ±5.2 mA. |
| 7 | GND | Ground reference for all I/O and internal circuitry; must be low-impedance to maintain noise immunity. |
| 14 | VCC | Positive supply terminal; decoupling capacitor (100 nF) recommended adjacent to pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Precision Schmitt-trigger thresholds | VT+ = 0.55×VCC to 0.65×VCC, VT− = 0.45×VCC to 0.55×VCC - Enables consistent switching points across voltage and temperature for reliable signal restoration. |
| Input clamp diodes | Integrated diodes to VCC and GND - Allow use of series current-limiting resistors when interfacing to voltages up to +16 V or down to −1.5 V. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - Prevents destructive latch-up during transient overvoltage events in harsh environments. |
| Unlimited input edge rates | No minimum rise/fall time requirement - Accepts arbitrarily slow analog-like inputs (e.g., thermistor or potentiometer wiper signals) without metastability. |
| Low dynamic power | CPD = 9 pF per gate - Enables low-power operation at high frequencies; dynamic power scales predictably as PD = CPD × VCC² × fi × N. |
Applications
| Motor Encoder Interface | Industrial Sensor Signal Conditioning |
|---|---|
|
Use Scenario: Quadrature A/B signals from optical or magnetic rotary encoders exhibit slow edges and EMI-induced jitter in motor drive cabinets. IC Role / Device Role / Timing Role: Each 74HC7014D channel conditions one encoder phase (A, B, index) by converting noisy analog transitions into clean, jitter-free square waves synchronized to system clock domain. Use Value: Eliminates false counting due to contact bounce or EMI, enabling sub-degree position resolution without FPGA-based filtering or external RC networks. |
Use Scenario: Analog outputs from pressure, temperature, or proximity sensors drift slowly and pick up 50/60 Hz mains noise in factory-floor wiring. IC Role / Device Role / Timing Role: Acts as a noise-immune threshold detector-converting sensor voltage into a robust digital flag indicating "threshold exceeded" with precise hysteresis. Use Value: Reduces false alarms in safety interlocks and process control systems by rejecting transients <120 mV while maintaining fast response to genuine threshold crossings. |
| Power Supply Sequencing Monitor | Legacy Bus Line Receiver |
|
Use Scenario: Monitoring delayed enable signals (e.g., 3.3 V rail after 12 V stabilization) where voltage ramps slowly over milliseconds. IC Role / Device Role / Timing Role: Buffers and sharpens ramping enable lines using Schmitt-trigger action to generate clean, monotonic logic transitions for downstream sequencers or microcontrollers. Use Value: Prevents partial initialization or race conditions in multi-rail systems by ensuring unambiguous HIGH/LOW state recognition despite slow supply ramp rates. |
Use Scenario: Interfacing TTL-compatible control lines (e.g., printer strobe, floppy drive select) to modern 3.3 V microcontrollers with marginal noise margins. IC Role / Device Role / Timing Role: Receives legacy 5 V logic signals with degraded edges and outputs clean 3.3 V–compatible waveforms with defined thresholds and fast edges. Use Value: Enables drop-in replacement of obsolete 74LS14 without redesigning PCB layout or adding external pull-ups or filters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC14DR | Standard hex Schmitt inverter (inverting); hysteresis ~0.4–0.8 V (not ratio-based); no input overvoltage tolerance beyond VCC+0.5 V. | Requires external inversion logic if non-inverting function needed; unsuitable for >VCC input interfacing. | Select only when inverting logic is acceptable and input voltage stays within rail limits. |
| MC74HC7014ADTR2G | Pin-compatible, same precision Schmitt specs, but in TSSOP-14 (4.4 mm width); slightly higher max ICC (13 mA vs. 10 mA at VCC = 6 V). | Same functional behavior; preferred for space-constrained boards where SO14 footprint is too large. | Choose for denser layouts; verify thermal derating (TSSOP has lower Ptot than SO14 at elevated ambient). |
Compared with SN74HC14DR, the 74HC7014D,112 delivers non-inverting logic and superior input ruggedness; versus MC74HC7014ADTR2G, it offers better thermal performance in SO14 and broader availability in industrial distribution channels.

FAQ
What is the maximum input voltage the 74HC7014D,112 can withstand without damage?
The 74HC7014D,112 allows input shorts to −1.5 V and +16 V relative to GND without disturbing other channels, provided input clamping current remains within ±20 mA. This is enabled by integrated clamp diodes to VCC and GND, permitting safe interface to sensors or switches operating outside the supply rails.
Does the 74HC7014D,112 require external pull-up or pull-down resistors on its inputs?
No-inputs are fully defined and self-biasing due to internal Schmitt-trigger structure. External resistors are unnecessary unless interfacing to voltages exceeding VCC, in which case a current-limiting resistor is required to keep clamp diode current ≤±20 mA per the Absolute Maximum Ratings table.
How does the hysteresis of the 74HC7014D,112 vary with supply voltage?
Hysteresis (VH = VT+ − VT−) scales linearly with VCC: at VCC = 6.0 V, VH = 160–240 mV; at VCC = 3.0 V, VH = 50–120 mV. Thresholds VT+ and VT− are specified as ratios (0.55×VCC and 0.45×VCC typ), ensuring consistent noise rejection percentage across the 2.0–6.0 V operating range.
Can the 74HC7014D,112 drive a 50 pF load at 10 MHz without signal degradation?
Yes-the 74HC7014D,112 has a typical transition time (tt) of 6–19 ns and CPD = 9 pF per gate. At VCC = 5 V and 10 MHz, dynamic power remains low (<1 mW/gate), and output rise/fall times stay well under 20 ns, ensuring clean edges into 50 pF loads without overshoot or excessive ringing.
