STMicroelectronics M74HCT244M1R Octal Buffer/Line Driver

The M74HCT244M1R from STMicroelectronics is an advanced high-speed CMOS OCTAL BUS BUFFER fabricated with silicon gate C2MOS technology. It is designed to provide the electrical characteristics that match or exceed those of the equivalent bipolar TTL family while maintaining the low power consumption of standard CMOS integrated circuits.

This particular device has two separate line drivers, each with four buffers or drivers with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high impedance OFF-state. The M74HCT244M1R operates at a voltage range of 4.5V to 5.5V, making it suitable for interfacing with TTL logic levels.

Key features of the M74HCT244M1R include:

• High-Speed: Typical tpd = 8ns at Vcc = 5V, CL= 50pF, TA= 25°C
• Low Power Dissipation: Icc = 4µA (max) at TA= 25°C
• Compatibility: Input levels are TTL voltage compatible, even when operated at Vcc = 5V
• 3-State Non-Inverting Outputs: For bus-oriented applications
• Pin and Function Compatibility: With 74 series 244

The device is packaged in a space-saving SO-20 package, which is ideal for applications where saving space is crucial. Its robust design ensures high durability and stable performance, making the M74HCT244M1R a reliable choice for a wide range of buffering and driving applications, including bus interface or signal buffering for computer, communication, and instrumentation systems.

STMicroelectronics provides this buffer/line driver with a commitment to reliability and performance, which is backed by their rigorous testing and quality assurance processes. The M74HCT244M1R is a testament to STMicroelectronics' dedication to providing industry-leading semiconductor solutions.
