74HCT154DB,112

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74HCT154DB,112 is a 4-to-16 line decoder/demultiplexer housed in a 24-lead SO plastic small outline package (SOT137-1). It decodes four binary weighted address inputs to sixteen mutually exclusive active LOW outputs. The device features two active LOW enable inputs and operates within a supply voltage range of 4.5 V to 5.5 V. It complies with JEDEC standards JESD8C and JESD7A, ensuring compatibility with TTL input levels.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix ',112' against current Nexperia documentation to confirm availability and exact packaging specifications. Confirm that the SO24 package variant aligns with your PCB footprint requirements. Ensure design compliance with the specified operating temperature ranges and absolute maximum ratings before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when TTL-compatible logic levels are required for a 4-to-16 decoding application. The HCT series ensures direct interface with standard TTL devices while maintaining CMOS performance characteristics. Verify that the 24-pin SO package dimensions fit the designated board space and thermal constraints.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74HC/HCT154 family of 4-to-16 line decoders and demultiplexers manufactured by Nexperia. The 'HCT' designation indicates compatibility with TTL logic levels, distinguishing it from the HC series which uses CMOS levels. The 'DB' suffix identifies the specific SO24 plastic small outline package configuration.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct pin-to-pin replacements include other manufacturers' 74HCT154 variants in SO24 packages. Verify electrical parameters such as propagation delay and output drive current match system requirements. Cross-reference package dimensions to ensure mechanical compatibility.
