74HCT154N,652

Signal Switches, Multiplexers, Decoders Overview

The NXP USA Inc. 74HCT154N,652 is a 4-to-16 line decoder/demultiplexer housed in a 24-pin PDIP package. It decodes four binary-weighted address inputs (A0 to A3) into sixteen mutually exclusive active LOW outputs (Y0 to Y15). The device features two active LOW enable inputs (E0 and E1); asserting either HIGH forces all outputs HIGH. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Decodes four binary-coded inputs into sixteen mutually exclusive outputs
• Features two active LOW input enables that force outputs HIGH when asserted
• Capable of functioning as a 1-to-16 demultiplexer using one enable as data input
• Includes input clamp diodes for interfacing with voltages exceeding VCC

Signal Switches, Multiplexers, Decoders Applications

• Address decoding for memory or peripheral selection
• Data distribution in digital communication systems
• Control logic for sequential state machines

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the component manufacturer against official Nexperia documentation, as the business was rebranded. Confirm the specific PDIP package type matches the required mechanical footprint. Ensure the HCT logic family compatibility aligns with the target TTL-level interface requirements. Validate the operating temperature range specifications against the intended environmental conditions.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a high-speed CMOS decoder compatible with Low-power Schottky TTL levels is required. The HCT series ensures direct interface with standard TTL logic without level shifting. Consider the 24-pin PDIP package if through-hole mounting is necessary for the design constraints. Verify that the wide supply voltage range meets the system power architecture.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74HCT154 family of 4-to-16 line decoders manufactured by Nexperia. It is pin-compatible with the 74HC154 variant but utilizes HCT logic levels for improved TTL interfacing. The device is designed for general-purpose digital applications requiring reliable decoding and demultiplexing functions.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74HCT154PW,118 serves as a surface-mount alternative in a TSSOP-24 package. Other variants include the 74HC154D and 74HC154BQ for different package types.
