Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the complete part number including the E4 suffix to ensure compliance with specific environmental or manufacturing standards. Confirm the TSSOP-16 package type matches your PCB footprint requirements. Check the datasheet for detailed electrical specifications and thermal performance data relevant to your application environment before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent decoding functions are required within a single package. The AHCT series ensures compatibility with 5V CMOS devices while accepting standard TTL input levels. Consider the TSSOP-16 package for space-constrained surface-mount designs requiring reliable operation across the extended industrial temperature range.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the SN74AHCT139 series, which provides high-speed decoding capabilities. The PWRE4 designation indicates a specific tape-and-reel packaging variant manufactured by Texas Instruments.
