STMicroelectronics M74HC11RM13TR

Overview

M74HC11RM13TR from STMicroelectronics is a high-speed CMOS triple 3-input AND gate in TSSOP-14 package, operating from 2V to 6V supply, with typical propagation delay of 9ns at 6V, symmetrical output drive (±4mA), and high noise immunity (28% VCC). It serves as a combinational logic building block in digital control, timing synchronization, and address decoding circuits.

For engineers reviewing the M74HC11RM13TR datasheet, M74HC11RM13TR pinout, M74HC11RM13TR application, or M74HC11RM13TR equivalent, key selection criteria include supply voltage range (2–6V), output drive capability (±4mA), propagation delay consistency (tPLH ≅ tPHL), input threshold stability across temperature, and TSSOP-14 footprint compatibility with space-constrained PCB layouts.

Technical Context

The M74HC11RM13TR implements three independent 3-input AND functions using silicon gate C2MOS technology, with four-stage buffered output architecture that enhances noise rejection and output stability. Each gate features diode-clamped inputs for ESD protection and transient voltage tolerance.

It operates within an extended industrial temperature range (−55°C to +125°C) and supports clean signal transitions via matched rise/fall times (e.g., 7–13ns typ. at 6V), enabling reliable use in synchronous logic chains where skew-sensitive fanout is required.

FAQ

Is M74HC11RM13TR pin-compatible with standard 74LS11?

Yes, M74HC11RM13TR is functionally and pin-compatible with 74LS11, sharing identical pinout (TSSOP-14), truth table, and logic function. However, it uses CMOS technology with higher noise immunity, wider supply range (2–6V vs. 4.75–5.25V), and lower power consumption-requiring no pull-up resistors on open-collector outputs unlike LS variants.

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

M74HC11RM13TR is characterized with CL = 50 pF in AC specifications, and its output drive (±4mA min.) supports stable operation into ≥100 pF loads at reduced edge rates. For loads exceeding 50 pF, layout best practices (short traces, local decoupling) and verification of tPLH/tPHL skew under actual load conditions are recommended.

Does this part support 3.3V-only operation without level shifters?

Yes, M74HC11RM13TR operates fully across 2V–6V, including 3.3V nominal supply. At VCC = 3.3V, VIH = 2.31V (70% VCC) and VIL = 0.99V (30% VCC) ensure clean interfacing with 3.3V microcontrollers and FPGAs without translation circuitry.

How does the C2MOS process improve reliability versus standard HC logic?

The silicon gate C2MOS process used in M74HC11RM13TR provides lower leakage (ICC ≤1µA), higher noise margins (28% VCC), and improved ESD tolerance (±20mA input diode current) compared to older planar CMOS. Its four-stage buffered output also reduces sensitivity to output loading variations and improves waveform fidelity.
