Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD74HC154ME4 is determined by strict equivalence across the following critical parameters: decoder/demultiplexer type with 1 x 4:16 circuit configuration, 24-SOIC package dimensions, single supply voltage range of 2V to 6V, output current specifications of 5.2mA for both high and low states, operating temperature range of -55°C to 125°C, and compliance certifications including ROHS3, MSL 1, and REACH Unaffected status.

The substitute parts are grouped into two categories:

MFR Recommended Substitute: CD74HC154M96 maintains identical electrical and mechanical specifications with the primary distinction being packaging format (Cut Tape & Digi-Reel versus Tube) and product status (Active versus Last Time Buy).

Parametric Equivalents: CD74HC4514M and CD74HC4515M share all critical electrical parameters and package specifications but represent alternative base product numbers within the 74HC decoder/demultiplexer family, each with identical functional performance for the 1 x 4:16 configuration.

Parameter Comparison

Engineering Selection Recommendations

CD74HC154M96 is the primary substitute for the CD74HC154ME4. Both parts share identical part number base (74HC154) and all electrical specifications. The CD74HC154M96 carries Active product status, providing superior long-term availability compared to the Last Time Buy status of the CD74HC154ME4. The packaging difference (Cut Tape & Digi-Reel versus Tube) does not affect electrical or mechanical compatibility. This part is recommended for new designs and ongoing production requiring extended component lifecycle.

CD74HC4514M and CD74HC4515M are parametric equivalents suitable for applications where the 1 x 4:16 decoder/demultiplexer function is required. Both maintain identical electrical performance, package specifications, and compliance certifications. Selection between these alternatives should be based on specific application requirements and internal design documentation, as they represent different base product numbers within the 74HC family. Both parts carry Last Time Buy status.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory and environmental compliance equivalent to the original CD74HC154ME4.

Frequently Asked Questions (FAQ)

Q: Can CD74HC154M96 be used as a direct replacement for CD74HC154ME4?

A: Yes. The CD74HC154M96 is electrically and mechanically equivalent to the CD74HC154ME4. Both parts share the same base product number (74HC154), identical electrical specifications, and 24-SOIC package dimensions. The only difference is packaging format and product status.

Q: What is the difference between CD74HC154M96 and CD74HC4514M?

A: Both parts are 1 x 4:16 decoder/demultiplexers in 24-SOIC packages with identical electrical specifications. The difference lies in the base product number (74HC154 versus 74HC4514). Both are functionally equivalent for the specified circuit configuration.

Q: Are the parametric equivalents (CD74HC4514M and CD74HC4515M) interchangeable with CD74HC154ME4?

A: Yes, for applications requiring a 1 x 4:16 decoder/demultiplexer function. All three parts share identical electrical parameters, package specifications, and compliance certifications. Interchangeability is determined by the functional requirements of the application, not by electrical or mechanical constraints.

Q: Does packaging format (Tube versus Cut Tape & Digi-Reel) affect compatibility?

A: No. Packaging format affects only procurement and handling procedures, not electrical or mechanical performance. The CD74HC154ME4 (Tube) and CD74HC154M96 (Cut Tape & Digi-Reel) are functionally identical when soldered to the PCB.

Q: Why is CD74HC154ME4 in Last Time Buy status?

A: Last Time Buy status indicates that the manufacturer is discontinuing this specific part number variant. Substitute parts with Active status, such as CD74HC154M96, are recommended for new designs and long-term production planning.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (CD74HC154M96, CD74HC4514M, and CD74HC4515M) are ROHS3 compliant with MSL 1 rating and REACH Unaffected status, matching the compliance profile of the CD74HC154ME4.
