CD74HCT240M96 Equivalent & Substitute Parts

Part Overview

The CD74HCT240M96 is an inverting buffer logic IC manufactured by Texas Instruments, designed for 5V logic applications requiring 3-state output capability. This 20-SOIC surface mount device functions as a 2-element, 4-bit buffer with inverting outputs, operating across the industrial temperature range of -55°C to 125°C. The part is Active status and ROHS3 compliant, making it suitable for modern electronic assemblies. Equivalent and substitute parts are identified to support design flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD74HCT240M96 is determined by the following critical parameters: logic type (Buffer, Inverting), functional configuration (2 elements, 4 bits per element), output type (3-State), supply voltage range (4.5V ~ 5.5V), package footprint (20-SOIC), and mounting type (Surface Mount). All identified substitutes maintain these core electrical and mechanical specifications. Variations in output current capability (6mA vs. 7.2mA) and operating temperature range remain within acceptable substitution criteria for this product category. Packaging format (Tape & Reel vs. Bulk) does not affect electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

All identified substitutes maintain Active product status and are electrically equivalent within the 74HCT240 logic family. The CD74HCT240M96 (Texas Instruments) and 74HCT240D,653 (Nexperia) both deliver 6mA output current and are ROHS3 compliant. The Fairchild Semiconductor alternatives (MM74HCT240WMX and MM74HCT240WM) provide higher output current capability at 7.2mA, suitable for applications requiring increased drive capability. Temperature range considerations apply: the CD74HCT240M96 and 74HCT240D,653 support extended industrial temperature operation to 125°C, while Fairchild parts operate to 85°C. Selection should align with specific application temperature requirements and output current demands.

Frequently Asked Questions (FAQ)

Q: Can MM74HCT240WMX replace CD74HCT240M96 in all applications? A: Electrical substitution is valid for standard logic applications. The higher output current (7.2mA vs. 6mA) and narrower temperature range (-40°C to 85°C vs. -55°C to 125°C) must be evaluated against application requirements.

Q: What is the difference between 20-SOIC and 20-SO packages? A: Both are 20-pin surface mount packages with identical 0.295" width and 7.50mm body dimensions. The designations reflect minor manufacturing variations but are mechanically and electrically interchangeable for PCB assembly purposes.

Q: Are all substitutes ROHS3 compliant? A: The CD74HCT240M96, 74HCT240D,653, and MM74HCT240WM are confirmed ROHS3 compliant. Compliance status for MM74HCT240WMX is not specified in available documentation.

Q: Does packaging format (Tape & Reel vs. Bulk) affect electrical performance? A: No. Packaging format affects only handling, storage, and supply chain logistics. Electrical and functional characteristics remain identical regardless of packaging format.

Q: Which substitute offers the best temperature range coverage? A: The 74HCT240D,653 (Nexperia) combines the full industrial temperature range (-40°C to 125°C) with 6mA output current and ROHS3 compliance, matching the CD74HCT240M96 specifications while offering manufacturer diversity.
