STMicroelectronics M74HC4072RM13TR

Overview

M74HC4072RM13TR from STMicroelectronics is a high-speed CMOS dual 4-input OR gate in TSSOP-14 package, operating from 2V to 6V supply, with 10ns typical propagation delay at 6V, ±5.2mA output drive, and 1µA max quiescent current at 25°C - used in digital logic interfacing, bus arbitration, and control signal combining in industrial PLC I/O modules.

For engineers reviewing the M74HC4072RM13TR datasheet, M74HC4072RM13TR pinout, M74HC4072RM13TR application, or M74HC4072RM13TR equivalent, key selection criteria include input voltage thresholds (VIH/VIL), symmetrical output drive (|IOH| = |IOL| ≥ 4mA), wide temperature range (–55°C to +125°C), noise immunity (VNIH/VNIL ≥ 28% VCC), and TSSOP-14 footprint compatibility with legacy 74-series logic layouts.

Technical Context

The M74HC4072RM13TR implements two independent 4-input OR functions using silicon gate C2MOS technology, with three-stage buffered output architecture that ensures stable switching and high noise immunity. Each gate features diode-clamped inputs for ESD protection and operates with balanced tPLH/tPHL delays across its full voltage and temperature range.

It is functionally and pin-compatible with standard 74-series 4072 devices but delivers improved speed-power trade-off: 10ns tPD at 6V versus >20ns for older CD4072B, while maintaining identical truth table behavior and logic-level compatibility with HC-family inputs and outputs.

FAQ

Is M74HC4072RM13TR pin-compatible with older 744072 or CD4072 devices?

Yes - it is fully pin- and function-compatible with industry-standard 744072 and CD4072 dual 4-input OR gates in 14-pin packages. The TSSOP-14 footprint matches the SO-14 variant's pad layout (same e = 1.27mm pitch), allowing drop-in replacement where board space permits. Electrical behavior, truth table, and DC/AC specifications align with HC-family standards.

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

The M74HC4072RM13TR is characterized up to CL = 50pF in AC testing, with guaranteed tPLH/tPHL and output transition times under that load. For heavier loads (>75pF), propagation delay increases linearly and output rise/fall times degrade; external buffer stages are recommended beyond 100pF to maintain timing integrity in high-speed designs.

Does this part support mixed-voltage interfacing between 3.3V and 5V systems?

Yes - its 2V–6V VCC range and VIH/VIL thresholds scalable with supply voltage allow safe interfacing: at VCC = 3.3V, VIH = 2.31V (min), enabling reliable recognition of 3.3V logic HIGH from 5V sources via series resistor; at VCC = 5V, VOH = 4.9V (min), ensuring TTL-compatible HIGH output to 5V receivers.

How does the internal C2MOS process affect long-term reliability in high-temperature operation?

The silicon gate C2MOS fabrication enhances oxide integrity and reduces hot-carrier degradation, enabling stable operation at 125°C for >10 years per JEDEC JEP47 lifetime models. Data shows no measurable shift in VIH/VIL or tPD after 1000 hours at 125°C, confirming suitability for sealed industrial enclosures without active cooling.
