SN74LVC244APW-P Equivalent & Substitute Parts

Part Overview

The SN74LVC244APW-P is a non-inverting buffer logic integrated circuit manufactured by Texas Instruments, classified within the 74LVC series. This device functions as a 2-element, 4-bit per element buffer with 3-state output capability, designed for signal buffering and line driving applications in low-voltage digital systems. The part is currently in active production status. Identifying equivalent and substitute parts becomes necessary when the primary part experiences supply constraints, inventory limitations, or when alternative packaging or qualification requirements must be met for specific applications.

Substitute Part Grouping Explanation

Substitute parts for the SN74LVC244APW-P are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are defined by the following parameters:

Electrical Equivalence Parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 4
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Voltage - Supply: 1.65V ~ 3.6V
• Operating Temperature Range: -40°C ~ 125°C (TA)

Mechanical Equivalence Parameters:

• Package / Case: 20-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The CLVC244AQPWRG4Q1 meets all electrical and mechanical equivalence criteria. This substitute maintains identical functional specifications, pin configuration, and package dimensions. The primary distinction is the packaging format (Tape & Reel versus prototype packaging) and automotive-grade qualification (AEC-Q100), which represents an enhancement rather than a deviation from the base specification.

Parameter Comparison

Engineering Selection Recommendations

The CLVC244AQPWRG4Q1 is a direct functional equivalent to the SN74LVC244APW-P. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and are housed in the same 20-TSSOP package. Both maintain active product status and ROHS3 compliance.

The CLVC244AQPWRG4Q1 carries automotive-grade qualification (AEC-Q100), which indicates enhanced reliability screening and qualification testing. This qualification does not alter the electrical or mechanical specifications but represents additional process controls and documentation suitable for automotive and high-reliability applications.

The packaging format difference (Tape & Reel versus prototype packaging) reflects distribution and handling methods rather than component functionality. Selection between these parts should be based on:

1. Inventory availability: The CLVC244AQPWRG4Q1 currently has higher stock levels (3810 Pcs versus 806 Pcs).
2. Application requirements: If automotive-grade qualification is required or preferred, the CLVC244AQPWRG4Q1 is the appropriate selection.
3. Packaging requirements: If Tape & Reel packaging is required for automated assembly processes, the CLVC244AQPWRG4Q1 is the appropriate selection.

Both parts are suitable for direct substitution in applications where the original SN74LVC244APW-P was specified.

Frequently Asked Questions (FAQ)

Q: Can the CLVC244AQPWRG4Q1 be used as a direct replacement for the SN74LVC244APW-P?

A: Yes. The CLVC244AQPWRG4Q1 is electrically and mechanically equivalent to the SN74LVC244APW-P. Both devices have identical logic function, pin configuration, package dimensions, electrical ratings, and operating temperature range. No circuit modifications are required for substitution.

Q: What is the difference between the SN74LVC244APW-P and CLVC244AQPWRG4Q1?

A: The primary differences are packaging format and automotive qualification. The SN74LVC244APW-P is supplied in prototype packaging, while the CLVC244AQPWRG4Q1 is supplied in Tape & Reel format. The CLVC244AQPWRG4Q1 carries AEC-Q100 automotive-grade qualification. All electrical and mechanical specifications are identical.

Q: Is the CLVC244AQPWRG4Q1 suitable for non-automotive applications?

A: Yes. Automotive-grade qualification indicates enhanced reliability and process controls. A part qualified to automotive standards is suitable for any application requiring the specified electrical and mechanical characteristics, including industrial, consumer, and commercial applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the SN74LVC244APW-P and CLVC244AQPWRG4Q1 are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q: What does 20-TSSOP package mean?

A: 20-TSSOP refers to a 20-pin Thin Shrink Small Outline Package with a body width of 0.173 inches (4.40mm). Both parts use this identical package, ensuring pin-for-pin compatibility and identical PCB footprint requirements.

Q: Can I use these parts interchangeably in production?

A: Yes, provided your application requirements are met by both parts' specifications. If your design specifies automotive-grade components, use the CLVC244AQPWRG4Q1. If your assembly process requires Tape & Reel packaging, use the CLVC244AQPWRG4Q1. Otherwise, either part is suitable for direct substitution.
