STMicroelectronics M74HC133B1R Integrated Circuit

The M74HC133B1R is a high-speed CMOS 13-input NAND gate fabricated with silicon gate C2MOS technology from STMicroelectronics, a global semiconductor leader known for its state-of-the-art electronic components. This integrated circuit is designed to offer the same high-speed performance of LSTTL combined with the true CMOS low power consumption. It is a versatile component used in a wide range of digital applications, from complex logic circuits to signal processing.

The device consists of a 13-input NAND gate, which is a fundamental building block in digital electronics. This logic gate performs the NAND operation on 13 inputs, providing an output which is the negation of the AND operation. In other words, the output of the M74HC133B1R is low only when all of its 13 inputs are high, otherwise, the output is high.

The M74HC133B1R operates on a supply voltage range from 2V to 6V, making it compatible with a variety of logic levels and suitable for interfacing with both TTL and CMOS circuits. Its low power consumption and high noise immunity are characteristic of CMOS technology, ensuring reliable performance in challenging electrical environments.

Key features of the M74HC133B1R include:

• High-Speed: Typically 10 ns at Vcc = 5V, CL = 50pF.
• Low Power Dissipation: Typically 20 µA at Vcc = 6V.
• High Noise Immunity: VNIH and VNIL are equal to 28% Vcc minimum.
• Output Drive Capability: Capable of driving 10 LSTTL loads.
• Symmetrical Output Impedance: With IOH = IOL = 4 mA at Vcc = 4.5V.
• Pin and Function Compatible with 74 Series Logic: Ensures easy integration into existing designs.
• ESD Performance: HBM: 1 kV; MM: 200 V; CDM: 1 kV.

The M74HC133B1R is provided in a DIP-16 package, which is a dual in-line package making it easy to work with in prototyping, educational environments, or for direct PCB mounting in commercial applications. Its robust design and proven reliability make it an excellent choice for engineers and designers looking for a high-performance NAND gate solution.

Whether you're designing complex digital systems or simple logic gates, the M74HC133B1R from STMicroelectronics is a reliable and efficient choice that combines the best of CMOS technology with practical packaging and high-speed operation.
