CD74AC541M Equivalent & Substitute Parts

Part Overview

The CD74AC541M is a non-inverting buffer logic IC manufactured by Texas Instruments, designed for 8-bit buffering applications with 3-state output capability. This device operates across a supply voltage range of 1.5V to 5.5V and is housed in a 20-SOIC surface mount package. The CD74AC541M is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design requirements and production needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD74AC541M is determined by the following critical parameters: logic type (non-inverting buffer), bit configuration (1 element, 8 bits), output type (3-state), output current capability (24mA), and physical package compatibility (20-SOIC surface mount). All substitute parts maintain these core electrical and mechanical specifications.

Substitute parts are grouped into two categories based on supply voltage range and operating temperature specifications:

Group 1: Texas Instruments Direct Substitutes — CD74AC541M96 maintains identical electrical specifications and supply voltage range (1.5V ~ 5.5V) with extended operating temperature range (-55°C ~ 125°C). Packaging differs only in format (Cut Tape & Digi-Reel vs. Tube).

Group 2: onsemi and Toshiba Alternatives — 74AC541SC, 74AC541SCX, MC74AC541DWG, MC74AC541DWR2G, and TC74AC541F(EL,F) provide functional equivalence with modified supply voltage ranges (2V ~ 6V or 2V ~ 5.5V) and reduced operating temperature ranges (-40°C ~ 85°C). Package variations include 20-SOIC and 20-SOP formats.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CD74AC541M96 — This Texas Instruments part is the direct functional equivalent with identical electrical specifications and extended temperature range. It maintains ROHS3 compliance and MSL 1 rating. The only difference is packaging format (Cut Tape & Digi-Reel vs. Tube), which does not affect electrical performance. This part is currently in active production status with high inventory availability.

Secondary Substitutes: onsemi 74AC541SC, 74AC541SCX, MC74AC541DWG, MC74AC541DWR2G — These parts provide functional equivalence with modified supply voltage range (2V ~ 6V) and reduced operating temperature range (-40°C ~ 85°C). All maintain 24mA output current and 3-state output configuration. Selection among these variants depends on packaging requirements: 74AC541SC and MC74AC541DWG are supplied in Tube format, 74AC541SCX in Cut Tape & Digi-Reel format, and MC74AC541DWR2G in Tape & Reel format. All are ROHS3 compliant with MSL 3 rating (168 Hours).

Alternative Substitute: TC74AC541F(EL,F) — This Toshiba part maintains core electrical specifications with supply voltage range of 2V ~ 5.5V and operating temperature range of -40°C ~ 85°C. The package format differs as 20-SOP (0.209", 5.30mm Width) versus the standard 20-SOIC. This part is RoHS Compliant with MSL 1 rating and is suitable for applications where package footprint variation is acceptable.

Frequently Asked Questions (FAQ)

Q: Can CD74AC541M96 be used as a direct replacement for CD74AC541M?

A: Yes. CD74AC541M96 is electrically identical to CD74AC541M with the same supply voltage range (1.5V ~ 5.5V), operating temperature range (-55°C ~ 125°C), output current (24mA), and 20-SOIC package. The only difference is packaging format (Cut Tape & Digi-Reel vs. Tube), which does not affect circuit performance.

Q: What are the key differences between Texas Instruments and onsemi substitutes?

A: Texas Instruments CD74AC541M96 maintains the original supply voltage range of 1.5V ~ 5.5V and extended operating temperature of -55°C ~ 125°C. onsemi parts (74AC541SC, 74AC541SCX, MC74AC541DWG, MC74AC541DWR2G) operate at 2V ~ 6V supply voltage with reduced operating temperature range of -40°C ~ 85°C. Both maintain identical output current and 3-state functionality. Selection depends on application voltage and temperature requirements.

Q: Is the Toshiba TC74AC541F(EL,F) compatible with the original CD74AC541M?

A: The Toshiba part maintains core buffer functionality and output current specifications. However, it uses a 20-SOP package (0.209", 5.30mm Width) instead of the standard 20-SOIC (0.295", 7.50mm Width), requiring PCB layout modification. Supply voltage range is 2V ~ 5.5V with operating temperature of -40°C ~ 85°C. Use this substitute only if package footprint change is acceptable for your application.

Q: What is the difference between 74AC541SC and 74AC541SCX?

A: Both parts are manufactured by onsemi with identical electrical specifications (2V ~ 6V supply, -40°C ~ 85°C operating temperature, 24mA output current, 3-state output). The difference is packaging format: 74AC541SC is supplied in Tube format, while 74AC541SCX is supplied in Cut Tape & Digi-Reel format. Electrical performance is identical.

Q: Which substitute has the highest inventory availability?

A: 74AC541SCX (onsemi) has the highest inventory with 20,200 pieces in stock, followed by MC74AC541DWR2G (onsemi) with 10,100 pieces. CD74AC541M96 (Texas Instruments) has 8,150 pieces available.

Q: Are all substitutes RoHS compliant?

A: Yes. CD74AC541M96 and all onsemi substitutes are ROHS3 compliant. TC74AC541F(EL,F) is RoHS Compliant. All parts meet environmental compliance requirements.
