Product details
Overview
HEF40106BT,653 from Nexperia is a hex inverting Schmitt trigger IC with six independent CMOS buffer stages, each featuring hysteresis-enabled input thresholds (VT+ = 3.0 V, VT− = 2.2 V at VDD = 5 V), rail-to-rail output swing, and operation across 3.0–15.0 V supply. It delivers 180 ns max propagation delay at 5 V/50 pF and supports −40 °C to +125 °C ambient operation in SO14 package. Used for noise-immune signal conditioning in industrial timing circuits.
For engineers reviewing the HEF40106BT,653 datasheet, HEF40106BT,653 pinout, HEF40106BT,653 application, or HEF40106BT,653 equivalent, key selection criteria include Schmitt-trigger hysteresis voltage (0.8 V typ. at 5 V), input clamp diode support for overvoltage-tolerant interfacing, symmetrical output drive (±4.2 mA at 15 V), and JEDEC JESD13-B compliance for industrial-grade reliability.
Technical Context
The HEF40106BT,653 implements six identical inverting Schmitt-trigger stages using standard CMOS process technology, each with independently clamped inputs enabling safe interface to signals exceeding VDD via external current-limiting resistors. Its static transfer characteristic defines distinct positive-going (VT+) and negative-going (VT−) thresholds, yielding hysteresis (VH = VT+ − VT−) that rejects noise up to ±0.4 V at 5 V supply.
Dynamic behavior is characterized by load-dependent propagation delays (tPHL/tPLH) and transition times (tTHL/tTLH), all specified at CL = 50 pF and tr/tf ≤ 20 ns. The device operates fully statically-no minimum clock or input frequency required-and exhibits low IDD (≤30 μA at 15 V, +125 °C), supporting battery-backed and low-power industrial control nodes.
Key Specifications

Pinout & Package
HEF40106BT,653 is housed in a plastic small outline package (SO14) per SOT108-1 standard: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, and moisture sensitivity level (MSL) 1. Pin 1 is marked by a notch or dot; pin numbering follows standard counter-clockwise sequence when viewed from top.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 3A, 5A, 9A, 11A, 13A | Schmitt-trigger input | Each accepts noisy analog or digital signals; internal clamp diodes permit overvoltage tolerance with series resistor. |
| 2Y, 4Y, 6Y, 8Y, 10Y, 12Y | Inverted output | CMOS rail-to-rail outputs capable of sourcing/sinking ≥4 mA at 15 V for direct interface to downstream logic or loads. |
| 7 | VSS (ground) | Primary reference node for all inputs, outputs, and internal circuitry; must be low-impedance connection. |
| 14 | VDD (supply) | Single positive supply input; decoupling capacitor (100 nF ceramic) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (3–15 V) | Eliminates need for separate voltage regulators in mixed-supply systems such as HVAC controllers with 5 V MCU and 12 V actuator drivers. |
| Schmitt-trigger hysteresis | 0.8 V typical at 5 V ensures clean edge generation from slow-rising sensor signals like thermistor voltage dividers. |
| Symmetrical output characteristics | Matched rise/fall times and drive strength simplify timing analysis in astable multivibrator feedback loops. |
| Input clamp diodes | Enable direct connection to 24 V field sensors using only a single series resistor-no external protection components needed. |
| JEDEC JESD13-B compliance | Guarantees interoperability with legacy 4000-series logic families and simplifies migration from older HEF40106 variants. |
Applications
| Waveform Shaping | Astable Multivibrator |
|---|---|
|
Use Scenario: Converting slow, noisy sine or triangle waveforms from oscillator ICs or transducer outputs into clean square waves for microcontroller capture timers. IC Role / Device Role / Timing Role: Each inverter stage acts as a threshold comparator with built-in hysteresis, reshaping edges while rejecting sub-threshold noise spikes. Use Value: Achieves jitter reduction below 5 ns RMS without external RC filtering-critical for precise time-of-flight measurement in ultrasonic distance sensors. |
Use Scenario: Generating fixed-frequency clock signals for LED flashers, PWM dimmers, or watchdog timeout circuits where crystal precision is unnecessary. IC Role / Device Role / Timing Role: Two cascaded inverters form a feedback loop with RC network; Schmitt thresholds define stable oscillation period independent of supply drift. Use Value: Frequency stability of ±3% over full temperature and voltage range eliminates need for trimmer capacitors or calibration firmware. |
| Monostable Multivibrator | Industrial Sensor Interface |
|
Use Scenario: Creating fixed-duration pulses from momentary switch closures or short-duration sensor events (e.g., door open detection, limit switch activation). IC Role / Device Role / Timing Role: One inverter stage provides edge-triggered input conditioning; second stage forms RC-delayed retriggerable one-shot with Schmitt reset path. Use Value: Pulse width accuracy of ±5% over −40 °C to +125 °C enables deterministic response timing in safety-critical machine guarding systems. |
Use Scenario: Interfacing high-impedance analog sensors (e.g., RTDs, photoresistors) to digital inputs of PLC modules or data loggers. IC Role / Device Role / Timing Role: Inverter configured as comparator with adjustable hysteresis sets trip point; input clamp diodes protect against cable-induced transients. Use Value: Enables direct 0–24 V sensor signal digitization using only one external resistor-reducing BOM count and PCB area by 40% vs. op-amp solutions. |
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 |
|---|---|---|---|
| SN74HC14DR | Lower VDD range (2–6 V); no input clamp diodes; 50% lower propagation delay at 5 V (19 ns typ.) | Not suitable for >6 V systems or overvoltage sensor interfaces; better for high-speed 3.3/5 V digital logic only. | Select when speed > noise immunity and supply is strictly ≤6 V; avoid for industrial 12/24 V environments. |
| CD40106BE | Same pinout but older TI process; wider parametric spread (e.g., VH = 0.5–1.2 V at 5 V); no JESD13-B compliance | Higher unit-to-unit variation affects multivibrator frequency consistency; lacks modern ESD robustness. | Acceptable for cost-sensitive consumer designs with relaxed timing and ESD requirements; not recommended for automotive or industrial use. |
Compared with SN74HC14DR and CD40106BE, HEF40106BT,653 uniquely combines 3–15 V operation, integrated input clamps, and JESD13-B certification-making it the only choice for ruggedized, multi-rail industrial signal conditioning where reliability across voltage and temperature extremes is mandatory.

FAQ
Can HEF40106BT,653 operate with a 3.3 V supply?
Yes, HEF40106BT,653 is fully specified down to 3.0 V supply. At 3.3 V, typical positive-going threshold is 1.7 V and hysteresis is 0.6 V, maintaining reliable noise rejection. Output VOH exceeds 3.2 V and VOL remains below 0.1 V, ensuring clean interfacing with 3.3 V CMOS logic families without level shifters.
What is the maximum capacitive load the outputs can drive reliably?
The outputs are characterized up to 50 pF in the datasheet, with propagation delay increasing linearly per 1 pF (e.g., +0.55 ns/pF at 5 V). For stable operation beyond 50 pF, add a series resistor (22–100 Ω) near the driver to dampen ringing. Total load-including PCB trace capacitance and downstream input capacitance-should remain ≤100 pF for timing-critical multivibrator designs.
How do the input clamp diodes function in overvoltage protection?
Each input has back-to-back clamp diodes connecting to VDD and VSS. When an input voltage exceeds VDD + 0.5 V or drops below VSS − 0.5 V, the corresponding diode conducts, limiting voltage excursion. A series current-limiting resistor (e.g., 10 kΩ for 24 V input) restricts clamp current to <10 mA, preventing damage while allowing safe interface to higher-voltage sensors.
Is HEF40106BT,653 suitable for automotive applications?
HEF40106BT,653 is qualified for −40 °C to +125 °C operation and meets JEDEC JESD13-B, but it is not AEC-Q100 qualified. It may be used in non-safety-critical automotive subsystems (e.g., cabin lighting control, HVAC fan speed feedback) where customer validation confirms robustness. For ASIL-B/C systems, AEC-Q100-qualified alternatives must be selected.
