74LCX841MTC Equivalent & Substitute Parts

Part Overview

The 74LCX841MTC is a D-Type Transparent Latch logic IC manufactured by onsemi, featuring a 10:10 circuit configuration with tri-state output capability. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The 74LCX841MTC operates across a 2V to 3.6V supply voltage range with a propagation delay of 1.5ns and is packaged in a 24-TSSOP surface mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LCX841MTC are qualified based on the following critical parameters:

• Logic Function: D-Type Transparent Latch with identical 10:10 circuit configuration
• Output Type: Tri-state output capability
• Package Compatibility: 24-TSSOP or 24-SSOP surface mount packages
• Electrical Performance: Output current rating of 24mA (high and low)
• Operating Temperature Range: -40°C to 85°C
• Independent Circuits: Single channel configuration
• Moisture Sensitivity: MSL 1 (Unlimited)

The substitute parts identified are from the Texas Instruments 74LVC series, which maintains functional equivalence while offering active product status and improved supply voltage compatibility (1.65V ~ 3.6V). All substitutes share the same base product number (74LCX841 / 74LVC841) and are certified for RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

SN74LVC841APWR is the primary substitute for the 74LCX841MTC. This part maintains identical package dimensions (24-TSSOP, 0.173" width), active product status, and ROHS3 compliance. With 18,130 units in stock, it offers superior supply availability compared to the obsolete 74LCX841MTC.

SN74LVC841APW provides an alternative with identical electrical and package specifications to the SN74LVC841APWR, differentiated only by packaging format (Tube versus Tape & Reel). This part is suitable for applications where tube packaging is preferred.

SN74LVC841ADBR is functionally equivalent but uses a 24-SSOP package (0.209", 5.30mm width) instead of the 24-TSSOP. This substitute is applicable only when PCB layout accommodates the wider package footprint. All three Texas Instruments substitutes are ROHS3 compliant and maintain active product status.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC841ADBR replace the 74LCX841MTC directly on existing PCBs?

A: Direct PCB replacement is not possible. The SN74LVC841ADBR uses a 24-SSOP package (5.30mm width) while the 74LCX841MTC uses 24-TSSOP (4.40mm width). PCB layout modification is required.

Q: What is the difference between SN74LVC841APWR and SN74LVC841APW?

A: Both parts are electrically and functionally identical. The difference is packaging format: SN74LVC841APWR is supplied in Tape & Reel (TR) format, while SN74LVC841APW is supplied in Tube format. Select based on your procurement and assembly requirements.

Q: Is the extended supply voltage range of the 74LCX841MTC (2V ~ 3.6V) critical for substitution?

A: The Texas Instruments 74LVC series substitutes operate at 1.65V ~ 3.6V, which covers the 74LCX841MTC range above 1.65V. If your application requires operation below 1.65V, the 74LCX841MTC cannot be substituted.

Q: How does the propagation delay difference (1.5ns vs. 2.7ns) affect substitution?

A: The 74LVC substitutes have a 1.2ns longer propagation delay. For timing-critical applications, verify that the 2.7ns delay meets system requirements before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three Texas Instruments substitutes (SN74LVC841APWR, SN74LVC841APW, and SN74LVC841ADBR) are ROHS3 compliant. The original 74LCX841MTC RoHS status is not specified.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including the 74LCX841MTC and all substitutes, have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
