Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74FCT162501ATPVG is determined by the following critical parameters:

• Logic Type: Must be Universal Bus Transceiver
• Number of Circuits: Must be 18-Bit
• Package / Case: Must be 56-BSSOP or compatible 56-pin SSOP variant
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must support -40°C ~ 85°C minimum
• Output Drive Current: Must support minimum 24mA on both high and low states
• Supply Voltage: Must operate within 4.5V ~ 5.5V range

Parts meeting all these criteria are classified as direct equivalents. Parts with minor deviations in output drive current or package width tolerance are classified as similar substitutes with noted parameter differences.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for New Designs):

74FCT162501ATPVCT (Cypress Semiconductor Corp) is the recommended substitute. This part maintains identical electrical specifications including 24mA output drive current and 4.5V to 5.5V supply voltage range. The part is currently in active production status, ensuring long-term availability and supply chain stability. It is packaged in 56-BSSOP with matching 7.50mm width and meets ROHS3 compliance requirements.

Compatible Substitutes (Functional Equivalents):

74FCT162501CTPVCT (Texas Instruments) provides functional equivalence with identical electrical parameters and package dimensions. However, this part carries obsolete status, limiting its suitability for new production designs despite current inventory availability.

CY74FCT16501ATPVC (Texas Instruments) offers higher output drive capability (32mA high, 64mA low) compared to the main part specification. This enhanced drive current provides additional design margin in applications requiring higher fan-out or longer trace lengths. Supply voltage specification is not provided for this part. The obsolete status and higher drive current make this suitable only for applications where increased output capability is beneficial.

Package Variant:

74FCT162H501CTPACT (Texas Instruments) uses a 56-TFSOP package with reduced width (6.10mm versus 7.50mm). This package variant may require PCB layout modifications and is classified as obsolete. Selection of this part should be limited to applications where the narrower package footprint provides specific design advantages.

Frequently Asked Questions (FAQ)

Q: Can 74FCT162501ATPVCT be used as a direct replacement for 74FCT162501ATPVG?

A: Yes. Both parts are 18-bit universal bus transceivers with identical electrical specifications (24mA output drive, 4.5V–5.5V supply), matching 56-BSSOP packages, and equivalent operating temperature ranges. The primary advantage of 74FCT162501ATPVCT is its active production status.

Q: What is the difference between 74FCT162501CTPVCT and 74FCT162501ATPVG?

A: Both parts share identical electrical parameters and package specifications. The distinction is manufacturer (Texas Instruments versus Renesas) and product status (both obsolete). Electrical performance and pin compatibility are equivalent.

Q: Why does CY74FCT16501ATPVC have higher output current specifications?

A: CY74FCT16501ATPVC provides 32mA high and 64mA low output drive compared to the standard 24mA specification. This higher drive capability is a design enhancement that does not prevent substitution but should be evaluated for thermal and power consumption implications in the target application.

Q: Can 74FCT162H501CTPACT be used in place of 74FCT162501ATPVG?

A: Electrical functionality is equivalent; however, the 56-TFSOP package is narrower (6.10mm versus 7.50mm) than the standard 56-BSSOP. PCB layout modifications are required. This substitution is viable only when the reduced package width provides specific design benefits.

Q: Which substitute part should be selected for new production designs?

A: 74FCT162501ATPVCT is the recommended choice due to active production status, ensuring supply chain continuity and long-term availability. All other substitutes carry obsolete designations.

Q: Are all substitute parts ROHS3 compliant?

A: 74FCT162501ATPVG, 74FCT162501CTPVCT, 74FCT162H501CTPACT, and CY74FCT16501ATPVC are all ROHS3 compliant. Compliance status for 74FCT162501ATPVCT is not specified in available documentation.
