CY74FCT162373CTPVC Equivalent & Substitute Parts

Part Overview

The CY74FCT162373CTPVC is a 16-bit transparent D-type latch with dual 8:8 channel configuration and tri-state output capability, manufactured by Texas Instruments in 48-SSOP surface mount packaging. This component operates within the 4.5V to 5.5V supply voltage range with 2ns propagation delay and 24mA output drive capability.

The CY74FCT162373CTPVC is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for legacy systems or new designs requiring compatible logic latch functionality.

Substitute Part Grouping Explanation

Substitute parts for the CY74FCT162373CTPVC are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalent (CY74FCT162373ATPVC): This substitute maintains identical electrical specifications including 4.5V ~ 5.5V supply voltage, 2ns propagation delay, and 24mA output drive. The part shares the same 74FCT logic series, dual 8:8 channel configuration, tri-state output architecture, and 48-BSSOP package footprint. The primary distinction is product status (active versus obsolete) and manufacturer (Cypress Semiconductor Corp versus Texas Instruments).

Manufacturer Recommended Substitute (SN74ALVCH162373LR): This substitute operates within a different voltage range (1.65V ~ 3.6V) and exhibits superior propagation delay (1ns versus 2ns) with reduced output drive (12mA versus 24mA). The SN74ALVCH162373LR belongs to the 74ALVCH logic series and maintains the same dual 8:8 channel configuration, tri-state output type, and 48-BSSOP package. This substitute is suitable for applications where lower voltage operation and faster switching are acceptable design parameters.

Substitution eligibility is determined by matching the following critical parameters: logic type (D-Type Transparent Latch), circuit configuration (8:8), output type (tri-state), package footprint (48-BSSOP), and mounting type (surface mount).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent): The CY74FCT162373ATPVC is the preferred substitute when maintaining identical electrical performance is required. This part is active in production, ROHS3 compliant, and shares all critical electrical parameters with the main part. Selection of this substitute eliminates design modification requirements and ensures functional equivalence.

For Design Flexibility (Manufacturer Recommended Substitute): The SN74ALVCH162373LR is suitable when system architecture permits operation at lower voltage levels (1.65V ~ 3.6V) and when faster propagation delay (1ns) provides design benefits. This part is active in production and ROHS3 compliant. Design implementation requires verification that reduced output drive capability (12mA versus 24mA) meets load requirements and that lower supply voltage is compatible with system power distribution.

Both substitute parts maintain ROHS3 compliance and are classified as REACH unaffected, supporting regulatory requirements for new product designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVCH162373LR replace the CY74FCT162373CTPVC in existing designs without modification?

A: The SN74ALVCH162373LR operates at different voltage levels (1.65V ~ 3.6V versus 4.5V ~ 5.5V) and provides reduced output drive (12mA versus 24mA). Direct substitution requires verification that the system power supply and load impedance are compatible with these electrical differences. The identical package footprint (48-BSSOP) and pin configuration enable physical replacement, but electrical system validation is necessary.

Q: What is the primary advantage of the CY74FCT162373ATPVC over the main part?

A: The CY74FCT162373ATPVC maintains identical electrical specifications while offering active product status and improved supply chain availability. This substitute eliminates the need for design modification while ensuring long-term component availability.

Q: Are all three parts pin-compatible?

A: Yes. All three parts share the 48-BSSOP package footprint with identical pin assignments for the D-Type transparent latch dual 8:8 channel configuration. Physical and electrical pin compatibility is maintained across all substitutes.

Q: Which substitute should be selected for new product designs?

A: The SN74ALVCH162373LR is the manufacturer-recommended substitute for new designs. This part is active in production, offers superior propagation delay performance, and supports lower voltage system architectures. The CY74FCT162373ATPVC is appropriate when legacy 5V system compatibility is required.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.
