Substitute Part Grouping Explanation

Substitution for the PI74FCT162245TVE is determined by strict equivalence across the following critical parameters:

Logic type: Transceiver, Non-Inverting
Element and bit configuration: 2 elements, 8 bits per element
Output capability: 3-State
Supply voltage range: 4.5V ~ 5.5V
Operating temperature range: -40°C ~ 85°C
Output current specifications: 24mA high and low
Base product number: 74FCT162245
Mounting type: Surface Mount

Substitute parts are grouped into two categories based on package configuration: 48-BSSOP (0.295" width) and 48-TFSOP (0.240" width). Parts within each package category maintain full electrical and functional equivalence to the original component.

Engineering Selection Recommendations

For direct replacement of the PI74FCT162245TVE in 48-BSSOP package configuration, the CY74FCT162245TPVCT from Cypress Semiconductor Corp is the primary choice due to its active product status and full electrical equivalence. This part maintains identical output current specifications (24mA, 24mA) and supply voltage range while offering current availability.

For applications requiring 48-TFSOP package format, the 74FCT162245CTPAG from IDT or 74FCT162245CTPAG8 from IDT provide active product status with equivalent electrical characteristics. Both parts maintain the required 24mA output current and 4.5V to 5.5V supply voltage specifications.

All listed substitute parts maintain ROHS3 compliance or equivalent environmental standards. Parts with MSL ratings of 1 (Unlimited) present no moisture sensitivity constraints during storage and handling. Parts with MSL-3 ratings require controlled storage conditions (168-hour maximum exposure at 85°C/85% RH).

Frequently Asked Questions (FAQ)

Q: Can I substitute the PI74FCT162245TVE with a part from a different package family?

A: Yes, but only within the specified package options. The 48-BSSOP (0.295" width) and 48-TFSOP (0.240" width) packages are mechanically and electrically compatible substitutes. PCB layout modifications may be required due to different package footprints.

Q: What is the difference between 48-BSSOP and 48-TFSOP packages?

A: The 48-BSSOP package has a width of 0.295" (7.50mm), while the 48-TFSOP package has a width of 0.240" (6.10mm). Both are surface-mount packages with 48 pins. Selection depends on available PCB space and design requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Not all substitute parts explicitly list ROHS3 compliance in their specifications. Parts from Cypress Semiconductor Corp do not specify RoHS status in the provided data. Verify RoHS compliance requirements with the component manufacturer or supplier before final selection.

Q: What does MSL rating mean, and why does it matter?

A: MSL (Moisture Sensitivity Level) indicates how sensitive a component is to moisture during storage and handling. MSL-1 parts have unlimited shelf life under standard conditions. MSL-3 parts must not exceed 168 hours of exposure at 85°C and 85% relative humidity. Select based on your storage and handling capabilities.

Q: Which substitute parts have active product status?

A: CY74FCT162245TPVCT, 74FCT162245CTPAG, and 74FCT162245CTPAG8 are classified as active products. All other substitutes are obsolete. Active parts offer better long-term availability for future procurement.

Q: Can I use parts with different output current ratings as substitutes?

A: No. The PI74FCT162245TVE specifies 24mA output current for both high and low states. Only substitute parts with identical 24mA specifications maintain full functional equivalence. Parts with different current ratings (such as 74FCT16245ATPAG with 32mA/64mA) are not direct substitutes.
