PI74VCX16241AE Equivalent & Substitute Parts

Part Overview

The PI74VCX16241AE is a non-inverting buffer IC manufactured by Diodes Incorporated, designed for logic signal buffering applications requiring 3-state output capability. This device operates across a 1.8V to 3.6V supply voltage range and is housed in a 48-TSSOP package. The product is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI74VCX16241AE is determined by strict alignment across the following critical parameters:

• Logic function: Non-inverting buffer with 4 elements, 4 bits per element
• Output configuration: 3-state output capability
• Output drive capability: 24mA high and low current
• Package form factor: 48-TFSOP surface mount
• Supply voltage range: Minimum 1.8V operation with 3.6V maximum
• Operating temperature range: -40°C to 85°C
• Regulatory compliance: ROHS3 compliance and REACH unaffected status

The SN74ALVC16244ADGGR from Texas Instruments meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALVC16244ADGGR is a direct functional substitute for the PI74VCX16241AE. Both devices share identical logic architecture, output drive specifications, package geometry, and thermal operating range. The substitute part maintains ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and assembly processes.

The primary distinction is product lifecycle status: the PI74VCX16241AE is obsolete while the SN74ALVC16244ADGGR maintains active production status. The substitute exhibits a marginally lower minimum supply voltage threshold (1.65V versus 1.8V), which provides expanded operational flexibility in low-voltage applications while maintaining full compatibility with systems designed for the original part.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVC16244ADGGR directly replace the PI74VCX16241AE in existing designs?

A: Yes. Both parts are pin-compatible 48-TSSOP packages with identical logic function, output drive capability, and thermal specifications. No circuit modifications are required.

Q: What is the significance of the different minimum supply voltages (1.8V vs. 1.65V)?

A: The substitute part operates at a lower minimum voltage. Systems designed for 1.8V minimum operation will function with the substitute. Applications requiring operation below 1.65V must use the original part specification.

Q: Are there packaging differences between these parts?

A: Both parts use the 48-TFSOP package with identical 0.240" width and 6.10mm dimensions. No PCB layout modifications are necessary.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 moisture sensitivity rating.

Q: Why is the original part listed as obsolete?

A: Product obsolescence reflects manufacturer lifecycle decisions. The substitute part from Texas Instruments provides equivalent functionality with active production support.
