Product details

Overview

74HCT14PW-Q100,118 from NXP Semiconductors is a hex Schmitt-trigger inverter IC operating at 4.5–5.5 V supply, with 10 ns propagation delay at 5 V, ±4 mA output drive, and automotive-grade AEC-Q100 qualification (Grade 2, −40°C to +105°C). It interfaces between noisy digital sensors and microcontroller inputs in engine control units.

For engineers reviewing the 74HCT14PW-Q100,118 datasheet, 74HCT14PW-Q100,118 pinout, 74HCT14PW-Q100,118 application, or 74HCT14PW-Q100,118 equivalent, key selection criteria include Schmitt-trigger hysteresis width (≈0.8 V), input threshold symmetry, rail-to-rail noise immunity, and guaranteed operation under automotive temperature and supply transients.

Technical Context

This device implements six independent CMOS Schmitt-trigger inverters in a single monolithic IC. Each gate features asymmetric input thresholds (V_IT+ ≈ 2.5 V, V_IT− ≈ 1.7 V at V_CC = 5 V) and TTL-compatible input levels, enabling robust signal conditioning of slow-rising or noisy waveforms.

The HCT logic family ensures compatibility with both TTL and CMOS systems while maintaining low static power consumption (< 1 µA typical at 25°C) and full 5 V operation-critical for legacy automotive subsystems retaining 5 V infrastructure.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	HCT - TTL-compatible input thresholds with CMOS power efficiency and 5 V rail operation
Supply Voltage	4.5 V to 5.5 V - Validated for automotive battery-sourced rails with load-dump tolerance
Propagation Delay	10 ns max at V_CC = 5 V, C_L = 50 pF - Enables reliable timing in sub-20 MHz clock/data conditioning paths
Hysteresis Width	≈0.8 V at V_CC = 5 V - Rejects noise spikes up to 800 mV without false triggering
Output Drive	±4 mA at V_CC = 5 V - Sufficient to directly drive LED indicators or small capacitive loads (≤30 pF)
AEC-Q100 Grade	Grade 2 (−40°C to +105°C) - Qualified for under-hood engine management and transmission control modules

Pinout & Package

TSSOP14 (Thin Shrink Small Outline Package, 14-pin, 0.65 mm pitch, body width 4.4 mm) - RoHS-compliant, surface-mount, thermally enhanced for automotive PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Input (A1–A6)	CMOS/TTL-compatible Schmitt-trigger input per inverter stage
2, 4, 6, 8, 10, 12	Output (Y1–Y6)	Inverted, buffered output with hysteresis; drives downstream logic or discrete loads
7	GND	Dedicated ground reference for all six gates; requires low-impedance PCB connection
14	V_CC	Single 5 V supply rail; decoupling capacitor (100 nF) required within 5 mm of pin

Key Features

Feature	Design Value
Schmitt-trigger input hysteresis	Enables clean digital reconstruction of analog-like signals (e.g., crankshaft position sensor outputs)
TTL-compatible input thresholds	Accepts standard 0.8 V/2.0 V logic levels without level-shifting circuitry
Automotive temperature range	Guaranteed functionality from −40°C to +105°C without derating or thermal monitoring
Low quiescent current	Typical I_CC < 1 µA at 25°C - supports always-on subsystems with minimal standby drain

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74HCS14QPWRQ1	Same AEC-Q100 Grade 2, but HCS family - higher noise immunity (V_IH/V_IL tighter), slower t_PD (15 ns)	Better for ultra-noisy environments; less suitable for >10 MHz edge rates	Prefer when EMI exceeds 100 mVpp and timing slack ≥5 ns exists
MC74VHC14DT	Industrial grade only (−40°C to +85°C), no AEC-Q100; faster t_PD (7.5 ns), lower hysteresis (0.5 V)	Not qualified for under-hood use; requires external thermal derating above 85°C	Select only for cabin-mounted modules with strict speed requirements and controlled ambient

Compared with SN74HCS14QPWRQ1 and MC74VHC14DT, the 74HCT14PW-Q100,118 delivers optimal balance of automotive qualification, 10 ns timing, and proven 0.8 V hysteresis - making it the default choice for cost-sensitive, thermally demanding engine and transmission control nodes.

FAQ

What is the minimum supply voltage for reliable operation of the 74HCT14PW-Q100,118?

The device is specified for operation from 4.5 V to 5.5 V. Below 4.5 V, input thresholds shift and hysteresis narrows, risking false triggering. NXP guarantees full functionality-including propagation delay, output drive, and noise margin-only within this range, as validated in AEC-Q100 stress testing.

Can the 74HCT14PW-Q100,118 drive a 100 pF capacitive load?

No. Its rated output drive is ±4 mA into 50 pF loads at 5 V. Driving 100 pF would exceed recommended slew rate limits, increasing propagation delay beyond 10 ns and potentially causing logic glitches. For >50 pF, add a buffer stage or reduce trace capacitance via layout optimization.

Is the 74HCT14PW-Q100,118 pin-compatible with non-automotive 74HCT14 variants?

Yes-pinout and electrical behavior match standard 74HCT14 devices in TSSOP14 packages. However, only the -Q100 suffix indicates AEC-Q100 qualification, including extended temperature validation, enhanced ESD protection (≥2 kV HBM), and lot-level automotive traceability documentation.

Does this IC require external pull-up or pull-down resistors on unused inputs?

Yes. Unused CMOS inputs must be tied to V_CC or GND to prevent floating states that cause increased current draw and potential oscillation. NXP recommends direct connection (not via resistors) for unused inputs to minimize leakage path uncertainty in automotive environments.
