STMicroelectronics M74HC04YRM13TR

Overview

M74HC04YRM13TR from STMicroelectronics is an automotive-grade high-speed CMOS hex inverter in SO14 package, operating from 2 V to 6 V supply, delivering 8 ns typical propagation delay at 6 V, 4 mA minimum output drive, and ±1 μA max quiescent current at 25 °C - used for signal inversion and logic-level translation in engine control units and body electronics.

For engineers reviewing the M74HC04YRM13TR datasheet, M74HC04YRM13TR pinout, M74HC04YRM13TR application, or M74HC04YRM13TR equivalent, key selection criteria include AEC-Q100 qualification, -40 °C to +125 °C temperature range, SO14 tape-and-reel packaging, symmetrical output impedance, and compatibility with legacy 74-series logic interfaces.

Technical Context

The M74HC04YRM13TR implements six independent CMOS inverter gates using silicon gate C2MOS technology, with three-stage internal buffering to enhance noise immunity and stabilize output transitions. Each input includes ESD protection circuits rated to 1 kV (CDM), 2 kV (HBM), and 200 V (MM).

It operates across a wide VCC range (2–6 V) with rail-to-rail input thresholds (VIH = 3.15 V, VIL = 1.35 V at 4.5 V), balanced tPLH/tPHL delays (8 ns typ. at 4.5 V), and output drive capability of |IOH| = IOL = 4 mA (min) at VCC = 4.5 V under defined load conditions.

FAQ

Is M74HC04YRM13TR pin-compatible with standard 74HC04 devices?

Yes - it uses identical SO14 pinout and logic function mapping as generic 74HC04 devices, including direct correspondence of inputs (1A–6A) and outputs (1Y–6Y). The marking "74HC04Y" on the package confirms functional and mechanical equivalence, with added automotive qualification and tighter parametric limits.

What is the maximum capacitive load this device can drive reliably?

The datasheet specifies AC characteristics with CL = 50 pF. While not explicitly rated beyond that, stable operation up to 75 pF is achievable at 4.5 V with ≤10 ns additional delay; for >50 pF loads, layout best practices (short traces, local decoupling) and verification under worst-case VCC/temperature are recommended.

Does M74HC04YRM13TR support 3.3 V logic systems?

Yes - its 2 V to 6 V operating range fully covers 3.3 V nominal systems. At VCC = 3.3 V, VIH is guaranteed ≥2.1 V and VIL ≤1.1 V, providing >0.8 V noise margin. Propagation delay increases to ~12 ns (typ.), remaining suitable for most MCU interface and peripheral control applications.

Can unused inputs be left floating?

No - floating CMOS inputs cause increased ICC, oscillation, and potential latch-up. All unused inputs must be tied to VCC or GND via ≤10 kΩ resistor. The internal protection diodes do not eliminate this requirement; ST recommends hard-wiring unconnected inputs to avoid undefined states and EMC issues.
