CD74HC154MG4 Equivalent & Substitute Parts

Part Overview

The CD74HC154MG4 is a 1 x 4:16 decoder/demultiplexer logic integrated circuit manufactured by Texas Instruments in the 74HC series. This surface mount device operates across a 2V to 6V supply range with output currents of 5.2mA for both high and low states. The part is currently in Last Time Buy status, indicating limited availability. Alternative equivalent and substitute parts are necessary to ensure design continuity and maintain supply chain flexibility for applications requiring decoder/demultiplexer functionality.

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC154MG4 is determined by the following critical parameters:

• Circuit Configuration: 1 x 4:16 decoder/demultiplexer topology
• Voltage Supply Range: 2V ~ 6V single supply operation
• Output Current Specifications: 5.2mA high and low output currents
• Package Type: 24-SOIC surface mount package with 0.295" (7.50mm) width
• Operating Temperature Range: -55°C ~ 125°C
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

All substitute parts listed maintain identical electrical characteristics and mechanical compatibility across these parameters. Substitutes differ only in packaging format (tube versus cut tape/digi-reel) and product status (active versus last time buy).

Parameter Comparison

Engineering Selection Recommendations

CD74HC154M96 is the primary recommended substitute. This part maintains full electrical and mechanical compatibility with the CD74HC154MG4 while offering Active product status, ensuring long-term availability and supply chain stability. The alternative packaging format (Cut Tape & Digi-Reel) accommodates both automated assembly and manual component handling workflows.

CD74HC4514M and CD74HC4515M are parametric equivalents that provide identical functional performance and electrical specifications. Both parts are currently in Last Time Buy status, similar to the original CD74HC154MG4. These alternatives are suitable for applications where supply from the primary substitute is constrained, provided that design documentation and procurement timelines account for limited availability windows.

All substitute parts carry ROHS3 compliance and MSL Level 1 ratings, meeting the same environmental and reliability standards as the original part.

Frequently Asked Questions (FAQ)

Q: Can CD74HC154M96 be used as a direct replacement for CD74HC154MG4?

A: Yes. Both parts share identical electrical specifications (voltage supply, output current, operating temperature range), circuit configuration (1 x 4:16), and package type (24-SOIC). The only difference is packaging format (cut tape/digi-reel versus tube) and product status (active versus last time buy).

Q: What is the difference between CD74HC4514M and CD74HC4515M?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. They differ only in base product number designation and internal circuit implementation details not specified in the provided parameters. Both maintain full compatibility with the CD74HC154MG4 across all critical substitution criteria.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (tube, cut tape, or digi-reel) does not affect electrical performance or functional characteristics. Format selection is determined by assembly process requirements and component handling procedures.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL Level 1 ratings, matching the environmental standards of the original CD74HC154MG4.

Q: Why is CD74HC154MG4 in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this specific packaging variant. CD74HC154M96 (active status) provides continuity for ongoing production requirements.
