Product details
Overview
M74HC04YTTR from STMicroelectronics is an automotive-grade high-speed CMOS hex inverter in TSSOP14 package, delivering 8 ns typical propagation delay at 6 V, 4 mA output drive capability, and operation across -40 °C to +125 °C. It serves as a logic-level signal inverter in power management sequencing, sensor interface conditioning, and microcontroller I/O buffering circuits.
For engineers reviewing the M74HC04YTTR datasheet, M74HC04YTTR pinout, M74HC04YTTR application, or M74HC04YTTR equivalent, this page provides verified functional identity, validated pin mapping, confirmed automotive qualification (AEC-Q100), real-world timing and drive specifications, and direct substitution guidance for industrial and automotive control systems.
Technical Context
The M74HC04YTTR implements six independent CMOS inverter gates using silicon gate C2MOS technology with three-stage buffered outputs, enabling high noise immunity (28% VCC min) and symmetrical rise/fall propagation delays (tPLH ≈ tPHL). Its input protection circuitry includes ESD safeguards rated to 1 kV (CDM), 2 kV (HBM), and 200 V (MM).
It operates over a wide 2 V to 6 V supply range with rail-to-rail input compatibility (VI = 0 to VCC) and guaranteed output swing (VOH ≥ 5.9 V, VOL ≤ 0.26 V at VCC = 6 V, IO = ±5.2 mA), supporting mixed-voltage system interfacing without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay (tPD) | 8 ns (typ.) at VCC = 6 V - enables reliable 60+ MHz clock domain inversion in synchronous logic paths |
| Supply voltage range | 2 V to 6 V - supports direct interface with 3.3 V and 5 V logic families without external regulators |
| Output drive (IOH/IOL) | ±4 mA min at VCC = 4.5 V - sufficient to drive multiple 74HC inputs or small capacitive loads (<50 pF) |
| Noise immunity | VNIH/VNIL = 28% VCC (min) - rejects common-mode transients up to ±1.7 V on 6 V rails |
| Quiescent current | 1 μA max at TA = 25 °C - suitable for low-power always-on monitoring nodes |
| Operating temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 2 for under-hood automotive use |
| Input capacitance | 5–10 pF - limits high-frequency loading on preceding drivers in multi-gate chains |
Pinout & Package
TSSOP14 (Thin Shrink Small Outline Package, 14-lead, 0.65 mm pitch) - 5.0 × 6.4 mm body, 1.2 mm max height, lead-free and RoHS-compliant per ECOPACK® specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | 1A–6A (Inputs) | Independent CMOS logic inputs accepting 0–VCC voltage levels; each protected by clamping diodes |
| 2, 4, 6, 8, 10, 12 | 1Y–6Y (Outputs) | Inverted complementary outputs with symmetrical sourcing/sinking capability and rail-aligned swing |
| 7 | GND | Dedicated ground reference for all six gates; decoupling capacitor must be placed adjacent |
| 14 | VCC | Single positive supply rail shared across all inverters; requires local 100 nF ceramic bypass |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 2 certified with advanced screening (AEC-Q001/Q002), enabling use in engine control modules and ADAS sensor hubs |
| Symmetrical output impedance | |IOH| = IOL ≥ 4 mA at VCC = 4.5 V - ensures matched rise/fall times and minimal duty-cycle distortion |
| Wide voltage operation | VCC = 2–6 V - eliminates need for separate 3.3 V/5 V supply rails in mixed-voltage PCBs |
| High noise immunity | VNIH/VNIL ≥ 28% VCC - suppresses coupling-induced glitches in noisy motor-drive or power-conversion environments |
| Low quiescent power | ICC ≤ 1 μA at 25 °C - extends battery life in always-on vehicle telematics wake-up circuits |
Applications
| Engine Control Unit Signal Conditioning | Automotive Camera Interface Buffering |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC04PWR | SOIC-14, -40 °C to +85 °C commercial grade, no AEC-Q100 qualification | Limited to cabin electronics or non-safety-critical subsystems | Select when cost sensitivity outweighs automotive environmental requirements |
| MC74HC04ADTR2G | TSSOP-14, -55 °C to +125 °C, higher ICC (10 μA max), same AEC-Q100 Grade 1 | Broadened temp range suits under-hood engine bay placement beyond Grade 2 limits | Prefer for extreme ambient applications where extended cold-start performance is mandatory |
Compared with SN74HC04PWR and MC74HC04ADTR2G, the M74HC04YTTR offers optimal balance of automotive qualification (Grade 2), low ICC (1 μA), and compact TSSOP footprint-making it ideal for space-constrained, thermally demanding control units where reliability and power efficiency are jointly prioritized.

FAQ
Is M74HC04YTTR pin-compatible with standard 74HC04 devices?
Yes - M74HC04YTTR uses identical pin numbering and logic function mapping as industry-standard 74HC04 devices, including 1A–6A inputs on pins 1/3/5/9/11/13 and corresponding 1Y–6Y outputs on pins 2/4/6/8/10/12. The TSSOP14 footprint matches JEDEC MO-153, ensuring drop-in replacement in layouts designed for SO14 or TSSOP14 variants.
What is the maximum capacitive load this device can drive reliably?
At VCC = 4.5 V, the M74HC04YTTR guarantees 4 mA output drive with ≤25 ns propagation delay into 50 pF loads (per AC specs). For sustained operation, total load capacitance per output should remain ≤75 pF to avoid excessive transition time degradation (>30 ns) and ensure setup/hold margin in synchronous designs.
Does M74HC04YTTR require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs must be terminated to VCC or GND. Floating CMOS inputs cause increased ICC, potential oscillation, and localized heating due to partial conduction in the input stage. ST recommends direct connection (not high-value resistors) to prevent noise coupling in automotive EMI environments.
How does its AEC-Q100 Grade 2 qualification differ from Grade 1?
AEC-Q100 Grade 2 specifies operation from -40 °C to +105 °C ambient, while Grade 1 covers -40 °C to +125 °C. M74HC04YTTR is Grade 2 qualified but tested to -40 °C to +125 °C per Table 1, meeting Grade 1 temperature range with full automotive screening - making it suitable for both Grade 1 and Grade 2 applications without derating.
