STMicroelectronics M74HC133RM13TR

Overview

M74HC133RM13TR from STMicroelectronics is a high-speed CMOS 13-input NAND gate in TSSOP-16 package, featuring 14 ns typical propagation delay at 6 V, ±4 mA symmetrical output drive, and operation across 2–6 V supply. It serves as a multi-input logic combiner in address decoding, bus arbitration, and enable control circuits for industrial microcontroller peripherals.

For engineers reviewing the M74HC133RM13TR datasheet, M74HC133RM13TR pinout, M74HC133RM13TR application, or M74HC133RM13TR equivalent, key selection criteria include wide VCC range (2–6 V), high noise immunity (28% VCC min), low ICC (1 µA max at 25°C), and guaranteed 13-input NAND functionality with buffered output stage.

Technical Context

The M74HC133 implements a single 13-input NAND function using silicon gate C2MOS technology with seven internal logic stages including input protection diodes and output buffering. Its symmetrical output impedance (|IOH| = IOL ≥ 4 mA) and balanced tPLH/tPHL delays ensure consistent timing in fan-out-sensitive control paths.

It operates over an extended temperature range (–55°C to +125°C) and supports fast edge rates (input tr/tf ≤ 400 ns at 6 V), making it suitable for noise-prone industrial environments where deterministic logic evaluation and static discharge resilience are required.

FAQ

Is M74HC133RM13TR pin-compatible with through-hole M74HC133B1R?

Yes - both share identical 16-pin DIP/SO/TSSOP pin numbering and logic function. Pin 1 (input A) to pin 7 (input G), pin 8 (GND), pin 9 (Y), pin 10 (input H) to pin 15 (input M), and pin 16 (VCC) are functionally and physically aligned across packages. No redesign needed when migrating from DIP to TSSOP.

Does M74HC133RM13TR require external pull-up resistors on inputs?

No - all 13 inputs have CMOS-compatible thresholds and internal protection circuitry. Pull-ups are unnecessary unless implementing wired-OR logic or open-drain interfacing. Unused inputs must be tied to VCC or GND to prevent floating states and excessive ICC.

What is the maximum capacitive load CL supported at 6 V supply?

The datasheet specifies AC characteristics at CL = 50 pF. Measured tPLH/tPHL remains within spec up to 75 pF at 6 V; beyond that, transition times increase linearly. For designs exceeding 50 pF, verify timing margins using the CPD = 29 pF value and equation ICC(opr) = CPD × VCC × fIN + ICC.

Can M74HC133RM13TR drive a 50 Ω transmission line directly?

No - its 4 mA output drive corresponds to ~1.25 kΩ effective impedance at 5 V, incompatible with 50 Ω line matching. Use a dedicated line driver (e.g., SN74LVC1G17) or series termination resistor (45–49 Ω) to avoid reflections and overshoot in high-speed routing.
