M74HC151YTTR

Overview

The M74HC151YTTR is an 8-input multiplexer manufactured by STMicroelectronics, belonging to the 74HC logic series. It features a single circuit configuration with one output and operates on a single power supply ranging from 2V to 6V. The device is housed in a 16-TSSOP surface-mount package with a width of 4.40mm. It supports high-speed operation with a propagation delay of 56ns and provides output currents of 5.2mA for both high and low states. Designed for automotive applications, it holds AEC-Q100 qualification and functions reliably within a temperature range of -40°C to +125°C.

Feature Summary

• Provides eight selectable data inputs routed to a single output via digital address lines
• Features Schmitt-trigger inputs to ensure noise immunity and stable switching performance
• Includes internal protection circuits against static discharge and transient excess voltage
• Delivers symmetrical output impedance for balanced signal transmission

Applications

• Automotive electronic systems requiring qualified logic components
• Data acquisition systems utilizing analog or digital signal routing
• Industrial control equipment managing multiple input sources
• Communication infrastructure handling signal selection tasks

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific part number matches the required automotive grade specifications. Ensure compatibility with existing PCB footprints and soldering profiles. Check for RoHS compliance status relevant to your manufacturing region. Validate storage conditions to maintain moisture sensitivity level integrity before assembly.

Selection Notes

Select this component when an 8-to-1 multiplexing function is required within a CMOS logic family. Consider the 2V to 6V operating voltage range for system power constraints. Evaluate the 16-TSSOP package dimensions against available board space. Assess the -40°C to +125°C temperature range against environmental operating conditions. Verify that the 56ns propagation delay meets the timing requirements of the target application.

Part Context

This device is part of the broader 74HC series of high-speed CMOS logic integrated circuits. It shares functional similarities with other multiplexers in the family but offers specific automotive qualification. The TSSOP packaging allows for compact surface-mount assembly. It complements other logic gates like inverters and AND gates within the same product line for complete system design.

Replacement Considerations

The Nexperia 74HC151PW,118 is documented as a parameter-equivalent substitute. Verify pinout compatibility and electrical characteristics before substitution. Ensure the alternative component meets the same automotive qualification standards if required.
