Product details
Overview
74HC9114D-Q100 from Nexperia is a 9-bit automotive-grade inverting Schmitt trigger buffer with open-drain outputs, designed for noise-immune signal conditioning in harsh environments. It operates from 2.0 V to 6.0 V, features TTL-compatible input thresholds (VT+ = 2.30–4.20 V at VCC = 6.0 V), supports -40 °C to +125 °C ambient range, and delivers jitter-free output transitions in automotive body control modules.
For engineers reviewing the 74HC9114D-Q100 datasheet, 74HC9114D-Q100 pinout, 74HC9114D-Q100 application, or 74HC9114D-Q100 equivalent, key selection criteria include Schmitt hysteresis (0.5–1.10 V), open-drain drive capability (±25 mA), propagation delay (10–165 ns depending on VCC and load), and AEC-Q100 Grade 1 qualification for under-hood use.
Technical Context
This device implements nine independent inverting Schmitt buffers, each with clamped inputs enabling safe interfacing to voltages exceeding VCC via current-limiting resistors. Its transfer characteristics define distinct positive-going (VT+) and negative-going (VT-) thresholds, delivering 0.5–1.10 V hysteresis to reject slow-rising noise on sensor or switch inputs.
The open-drain outputs support wired-OR logic, level translation, and pull-up flexibility across mixed-voltage systems. Internal clamp diodes, JESD7A/JESD8C compliance, and HBM ESD rating >2000 V ensure robustness in automotive wiring harnesses subject to load dump and EMI.
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 microcontrollers and legacy 12 V–regulated subsystems. |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for engine bay and transmission control unit deployment. |
| Input Threshold Hysteresis | 0.5 V to 1.10 V - Rejects contact bounce, EMI-induced glitches, and slow-edge signals from mechanical switches or analog sensors. |
| Propagation Delay | 10 ns (VCC = 6.0 V, CL = 50 pF) - Supports high-speed digital signal conditioning in CAN/LIN bus wake-up circuits and door module status monitoring. |
| Output Drive Capability | ±25 mA - Sinks sufficient current to directly drive LEDs, relays, or optocouplers without external transistors. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Withstands handling and in-system electrostatic discharge in assembly and service environments. |
| Input Clamp Diodes | Integrated - Allows safe connection of inputs to voltages up to 12 V using series current-limiting resistors. |
Pinout & Package
74HC9114D-Q100 is housed in a plastic small outline package (SO20), SOT163-1 variant, with 20 leads and 7.5 mm body width. Pin 1 is marked by a notch or dot; pin numbering follows standard SOIC convention with GND at pin 10 and VCC at pin 20.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A8 (pins 1–9) | Inverting Schmitt input | Accepts slow or noisy signals; converts them to clean digital edges with defined VT+ and VT- thresholds. |
| GND (pin 10) | Ground reference | Common return path for all inputs, outputs, and internal logic; must be low-impedance for noise immunity. |
| Y0–Y8 (pins 11–12, 13–19) | Open-drain inverting output | Sinks current only; requires external pull-up to define HIGH level-enables voltage-level translation and bus arbitration. |
| VCC (pin 20) | Positive supply | Power rail for CMOS logic core; decoupling capacitor (100 nF) recommended within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input thresholds | VT+ = 2.30–4.20 V at VCC = 6.0 V enables seamless integration with legacy 5 V logic without level shifters. |
| Integrated input clamp diodes | Permits direct connection to 12 V automotive signals using simple series resistors-eliminates external protection components. |
| Unlimited input rise/fall times | Supports debouncing of mechanical switches and slow-slew sensor outputs without timing constraints or added RC networks. |
| Latch-up immunity >100 mA | Meets JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events in vehicle power domains. |
| Low ICC at 6.0 V | Max 160 μA over full temperature range - minimizes quiescent power in always-on modules like smart junction boxes. |
Applications
| Body Control Module (BCM) | Door Module Interface |
|---|---|
Use Scenario: Monitoring door ajar, trunk open, and hood latch switches exposed to vibration and moisture. IC Role / Device Role / Timing Role: Inverting Schmitt buffer conditioning slow, noisy mechanical switch signals before MCU GPIO sampling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVTH162244DGGR | 16-bit non-inverting LVTH buffer; no Schmitt inputs; 3.3 V only; push-pull outputs. | Requires external hysteresis for noisy inputs; unsuitable for 12 V interface without level shifting. | Select only when noise immunity is not required and system uses 3.3 V logic exclusively. |
| MC74VHC1GT50DTT1G | Single-channel inverting Schmitt buffer; SOT-23; 2.0–5.5 V; open-drain; no input clamps. | Lacks integrated clamp diodes; cannot safely interface to >VCC voltages without external protection. | Use for space-constrained single-signal conditioning where 12 V interface is not needed. |
Compared with SN74LVTH162244DGGR and MC74VHC1GT50DTT1G, the 74HC9114D-Q100 uniquely combines 9-channel density, automotive qualification, input clamping, and Schmitt hysteresis in a single SO20 package-making it optimal for cost-sensitive, high-reliability multi-sensor nodes.

FAQ
Can 74HC9114D-Q100 interface directly with 12 V automotive switches?
Yes. Its integrated input clamp diodes allow connection to 12 V signals when used with appropriate series current-limiting resistors (e.g., 10 kΩ). This eliminates external protection diodes and simplifies PCB layout while maintaining AEC-Q100 compliance.
What is the maximum capacitive load supported on its open-drain outputs?
The device is characterized up to 50 pF load capacitance per output, with propagation delay increasing from 10 ns (CL = 50 pF, VCC = 6.0 V) to 28 ns at maximum rated conditions. For loads >50 pF, derate timing margins and verify signal integrity with oscilloscope validation.
Does it require external pull-up resistors on Y0–Y8 outputs?
Yes. As open-drain outputs, Y0–Y8 must be pulled up externally to define the HIGH logic level. Pull-up value depends on speed and drive strength needs: 1–10 kΩ is typical for 5 V systems; lower values improve rise time but increase static current.
How does its Schmitt hysteresis improve performance versus standard inverters?
Its 0.5–1.10 V hysteresis creates two distinct switching thresholds (VT+ and VT−), preventing oscillation on slow or noisy edges. This eliminates false triggering from EMI, contact bounce, or long-trace ringing-critical for reliable switch and sensor interfacing in automotive environments.
