HEF4051BTT-Q100,11

Analog Switches, Multiplexers, Demultiplexers Overview

The HEF4051BTT-Q100,11 is an automotive-qualified single-pole octal-throw analog switch manufactured by Nexperia. It operates within a supply voltage range of 3.0 V to 15.0 V and features three digital select inputs (S1, S2, S3), eight independent bidirectional input/output channels (Yn), a common channel (Z), and an active LOW enable input (E). The device supports ambient temperatures from -40 °C to +125 °C and includes internal clamp diodes for overvoltage protection. It is housed in a TSSOP16 package (SOT403-1) with 16 leads and a body width of 4.4 mm.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the package type and temperature rating. Ensure that the procurement specifications align with the required automotive grade qualifications and environmental operating ranges defined in the product data sheet.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing systems requiring an 8-channel analog switch with automotive reliability ratings. Consider the TSSOP16 package dimensions for PCB layout constraints and verify that the supply voltage requirements fall within the specified 3.0 V to 15.0 V operational window.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the HEF4051B-Q100 family of 8-channel analog multiplexer/demultiplexers. The 'TT' designation specifically identifies the TSSOP16 plastic thin shrink small outline package variant, while the '-Q100' suffix indicates compliance with Automotive Electronics Council standards for Grade 1 applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The HEF4051BT-Q100 serves as a direct functional substitute utilizing the SO16 package instead of TSSOP16. Designers must account for differences in physical footprint and thermal dissipation characteristics when transitioning between these package variants.
