STMicroelectronics M54HC147F1: High-Speed CMOS Logic 10-to-4 Line Priority Encoder

The M54HC147F1 is a high-performance integrated circuit manufactured by STMicroelectronics, designed to provide efficient encoding solutions for digital systems. This 10-to-4 line priority encoder is part of the HC (High-speed CMOS) family, offering a perfect blend of speed and low power consumption, making it suitable for a wide range of applications in modern electronic equipment.

The device features 10 input lines and converts the active input with the highest priority into a 4-bit binary code at the output, with additional GS (Group Select) and EO (Enable Output) control functions. The priority encoding ensures that if two or more inputs are active simultaneously, the input with the highest priority is represented at the output.

The M54HC147F1 operates over a broad voltage range from 2V to 6V and provides standardized, symmetrical output characteristics with high noise immunity. The balanced propagation delays between inputs and outputs contribute to its reliable and predictable performance in digital systems.

Key features of the M54HC147F1 include:

• High-Speed Operation: Fast propagation times and high-speed data processing capabilities are hallmarks of the HC series.
• Low Power Dissipation: The CMOS technology used in the M54HC147F1 ensures low power consumption, making it ideal for battery-operated devices.
• Priority Encoding: The encoder ensures that the highest priority signal is always encoded, simplifying decision-making processes in digital circuits.
• Wide Operating Voltage Range: Compatibility with a range of power supply levels increases the versatility of the device across different applications.
• Output Control Functions: With GS and EO pins, the M54HC147F1 provides additional control for cascading and integration with other logic components.

The M54HC147F1 is available in a standard DIP (Dual In-line Package), making it easy to integrate into both prototyping environments and production printed circuit boards (PCBs). Its robustness and compliance with JEDEC standards ensure its reliability in the most demanding conditions.

Whether used in computer systems, communication devices, or complex automation machinery, the STMicroelectronics M54HC147F1 priority encoder stands out as a smart choice for designers looking to enhance system efficiency and performance.
