CD74HC147MT

Signal Switches, Multiplexers, Decoders Overview

The CD74HC147MT is a high-speed CMOS logic device manufactured by Texas Instruments, functioning as a 10-to-4 line priority encoder. It converts ten active-low input lines into a corresponding three-bit binary code with an additional active-low zero indicator output. The component operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -55°C to +125°C. Packaged in a 16-pin SOIC surface-mount format, it features buffered inputs and outputs for improved signal integrity.

Signal Switches, Multiplexers, Decoders Feature Summary

• Converts ten active-low data inputs into a four-bit active-low binary-coded decimal output
• Features buffered inputs and outputs to maintain signal integrity across the logic family
• Supports operation across an extended industrial temperature range for robust environmental performance

Signal Switches, Multiplexers, Decoders Applications

• Digital encoding systems requiring priority-based input selection
• Keyboard matrix scanning circuits
• Data acquisition systems handling multiple interrupt sources

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix MT against the official Texas Instruments datasheet to confirm the SOIC-16 package and tape-and-reel shipping configuration. Ensure the order matches the exact part number to avoid confusion with similar HC series variants or different packaging options such as PW or PWR. Cross-reference the manufacturer's latest documentation for any potential product changes or lifecycle status updates before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single priority encoder is required to handle ten distinct input signals. The HC series offers compatibility with standard 5V logic levels while supporting lower voltage operation down to 2V. Consider the SOIC-16 package dimensions for PCB layout constraints and verify that the propagation delay characteristics meet the timing requirements of the target application circuit.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the Texas Instruments CD74HC series of high-speed CMOS logic components. The series is designed for general-purpose digital applications requiring low power consumption and high noise immunity. The CD74HC147 specifically addresses the need for converting multiple input lines into a compact binary representation, serving as a fundamental building block in complex digital control architectures.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Compatible substitutes include the SN74HC147MT and other industry-standard 10-to-4 priority encoders in SOIC-16 packages. Verify pinout compatibility and electrical specifications such as supply voltage ranges and propagation delays before substitution. Ensure that any alternative component meets the same temperature and logic level requirements.
