STMicroelectronics M74HC03RM13TR

Overview

M74HC03RM13TR from STMicroelectronics is a high-speed CMOS quad 2-input open-drain NAND gate in TSSOP-14 package, operating from 2V to 6V supply, with 8ns typical propagation delay at 6V, 1µA max quiescent current at 25°C, and ±20mA output sink capability-used for wired-AND bus interfacing and LED driving in industrial control logic.

For engineers reviewing the M74HC03RM13TR datasheet, M74HC03RM13TR pinout, M74HC03RM13TR application, or M74HC03RM13TR equivalent, key selection factors include open-drain output configuration, VCC range compatibility (2–6V), guaranteed noise immunity (28% VCC), balanced tPLH/tPHL delays, and TSSOP-14 thermal performance up to 125°C.

Technical Context

The M74HC03RM13TR implements four independent NAND gates with open-drain outputs, requiring external pull-up resistors for logic HIGH assertion. Each gate features silicon gate C2MOS construction with three-stage buffered output for stable switching and high noise immunity.

It supports wired-AND bus topologies by enabling multiple outputs to share a common line without contention, and functions as a current-sink driver for LEDs or low-side switches-leveraging its 5.2mA sink capability at 6V with ≤0.4V VOL under load.

FAQ

Can M74HC03RM13TR be used with a 3.3V supply?

Yes. The device operates across 2V to 6V, including 3.3V nominal supply. At VCC = 3.3V, VIH is guaranteed ≥2.31V and VIL ≤ 1.16V, with tPD ≈ 12ns (typ.) and VOL ≤ 0.33V at 4mA sink-fully compatible with 3.3V logic families.

What pull-up resistor value is recommended for open-drain outputs?

A 4.7kΩ pull-up to VCC is typical for 1MHz bus speeds and 5.2mA sink capability. For faster edges or lower noise, 2.2kΩ may be used-but increases static power. Values >10kΩ risk slow rise times in noisy environments per CL = 50pF test condition.

Does M74HC03RM13TR support hot insertion?

No. While inputs feature ±20mA diode protection, the device lacks dedicated hot-swap circuitry or power sequencing controls. Applying VCC before or after signal inputs may cause latch-up or undefined states-power sequencing per recommended operating conditions is required.

Is there an automotive-grade version of this part?

STMicroelectronics offers the M74HC03RM13TR in industrial grade (-55°C to +125°C). An AEC-Q100 qualified variant is not listed in official documentation; for automotive use, consider the pin-compatible STL74HC03TTR, qualified to Grade 2 (-40°C to +105°C) with enhanced ESD and HTOL testing.
