CD74HCT154M Equivalent & Substitute Parts

Part Overview

The CD74HCT154M is a decoder/demultiplexer logic integrated circuit manufactured by Texas Instruments in a 24-SOIC surface mount package. This component functions as a 1 x 4:16 decoder, converting 4-bit binary input to 16 individual output lines. The main part is currently in Last Time Buy status, making identification of active equivalent parts essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD74HCT154M is determined by strict equivalence across the following critical parameters:

• Base product number (74HCT154 series)
• Decoder/demultiplexer circuit configuration (1 x 4:16)
• Output current specifications (4mA high, 4mA low)
• Supply voltage range (4.5V ~ 5.5V)
• Package type (24-SOIC)
• Surface mount mounting type

All identified substitute parts maintain these core electrical and mechanical specifications. Variations in packaging format (tube, cut tape, bulk) and product status do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

CD74HCT154M96 (Texas Instruments) is the primary substitute, maintaining identical electrical specifications and package configuration while offering active product status and availability in cut tape and Digi-Reel formats suitable for automated assembly processes.

74HCT154D,653 (NXP Semiconductors) provides functional equivalence with ROHS3 compliance and active status. The operating temperature range minimum of -40°C (versus -55°C for the main part) represents the only specification variance and is suitable for applications not requiring extended low-temperature operation below -40°C.

Both substitutes are qualified alternatives for direct replacement in 24-SOIC surface mount applications requiring 74HCT154 decoder/demultiplexer functionality.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT154M96 be used as a direct replacement for CD74HCT154M?

A: Yes. Both parts share identical electrical specifications (4mA output current, 4.5V ~ 5.5V supply, -55°C ~ 125°C operating range) and package configuration (24-SOIC). The difference is packaging format (tube versus cut tape/Digi-Reel) and product status (Last Time Buy versus Active).

Q: What is the key difference between the NXP 74HCT154D,653 and Texas Instruments alternatives?

A: The NXP part maintains all core electrical and package specifications. The operating temperature minimum is -40°C instead of -55°C. This substitution is valid for applications operating above -40°C.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 24-SOIC package with identical pinout and functional configuration as 1 x 4:16 decoder/demultiplexers.

Q: Does packaging format affect functional performance?

A: No. Tube, cut tape, and bulk packaging formats do not affect electrical performance or circuit operation. Selection depends on assembly process requirements and procurement volume.

Q: Are all substitutes RoHS3 compliant?

A: Yes. CD74HCT154M, CD74HCT154M96, and 74HCT154D,653 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
