74HCT154BQ,118

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74HCT154BQ,118 is a 4-to-16 line decoder/demultiplexer in the HCT logic family. It decodes four binary weighted address inputs (A0 to A3) into sixteen mutually exclusive active LOW outputs (Y0 to Y15). The device includes two active LOW enable inputs (E0 and E1); a HIGH level on either forces all outputs HIGH. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input levels. Packaged in a DHVQFN24 (SOT815-1) format with dimensions of 3.5 x 5.5 x 0.85 mm, it supports an operating temperature range from -40 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Decodes four binary-coded address inputs into sixteen mutually exclusive active LOW outputs
• Features dual active LOW enable inputs that force outputs HIGH when asserted
• Compatible with TTL input voltage levels for direct interfacing
• Includes input clamp diodes to allow interface with voltages exceeding VCC

Signal Switches, Multiplexers, Decoders Applications

• 1-of-16 decoding circuits
• 1-to-16 demultiplexing applications
• Memory address decoding systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific BQ suffix corresponds to the DHVQFN24 package configuration required for your design. Confirm the HCT logic family compatibility with your system's 5 V logic levels. Ensure thermal management meets the specified power dissipation limits for the leadless package type during operation.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when TTL-level inputs are required alongside CMOS output characteristics. The DHVQFN24 package offers a compact solution for space-constrained PCB layouts. Verify that the application requires active LOW outputs and mutual exclusivity among the sixteen decoded lines.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74HCT154 series of 4-to-16 line decoders manufactured by Nexperia. The 'BQ' designation specifically identifies the DHVQFN24 leadless package variant. It shares functional specifications with other packages like SO24 and TSSOP24 but differs in physical footprint and thermal properties.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct replacements include 74HC154BQ,118 for CMOS input levels or 74HCT154D,118 and 74HCT154PW,118 for alternative packaging options.
