CD74HCT154M96

Overview

The CD74HCT154M96 is a high-speed CMOS decoder/demultiplexer manufactured by Texas Instruments. It features one circuit with four inputs and sixteen outputs, housed in a 24-SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55 °C to +125 °C. Propagation delay is specified at 40 ns @ 4.5V with 50pF load. Output drive capability is 4 mA for both high and low states.

Feature Summary

• Provides decoding or demultiplexing functionality via a single 4-to-16 channel configuration.
• Utilizes high-speed CMOS technology compatible with standard TTL logic levels.
• Designed for surface-mount installation using the 24-pin SOIC form factor.

Applications

• Address decoding in microprocessor-based systems
• Data distribution in digital communication circuits
• Memory chip selection logic

Procurement Notes

Verify the specific suffix M96 against the manufacturer datasheet to confirm tape-and-reel packaging specifications. Ensure the design accommodates the 24-SOIC footprint dimensions and thermal requirements for the extended industrial temperature range. Cross-reference RoHS compliance status with current environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a single 4-to-16 decoder is required in a surface-mount application. The HCT series ensures compatibility with 5 V TTL logic inputs. Verify that the 40 ns propagation delay meets system timing constraints. Confirm that the 24-SOIC package fits the available PCB real estate and soldering profile capabilities.

Part Context

This part belongs to the Texas Instruments CD74HCT154 family of decoders and demultiplexers. It is part of the broader 74HCT logic series, which bridges HC speed with TTL input compatibility. The M96 suffix typically denotes specific packaging or handling variations within the standard 74HCT154 product line.

Replacement Considerations

CD74HCT154M96E4 is a verified equivalent variant within the same family offering identical logical function and pinout compatibility.
