Substitute Part Grouping Explanation

Substitution of the 74FCT162373ATPACT is determined by strict equivalence across the following critical parameters:

• Logic function: D-Type Transparent Latch with identical 2 Channel 8:8 circuit configuration
• Output architecture: Tri-state output capability
• Package form factor: 48-TFSOP surface mount package
• Pin compatibility: Identical pinout and signal routing
• Operating temperature range: -40°C to 85°C minimum requirement
• Compliance certifications: ROHS3 and REACH status alignment

The SN74ALVCH162373GR meets all substitution criteria while offering enhanced electrical characteristics within a compatible voltage operating window.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALVCH162373GR is the designated manufacturer-recommended substitute for the obsolete 74FCT162373ATPACT. Both components maintain identical functional architecture, pinout compatibility, and package specifications. The substitute part carries active product status, ensuring long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH unaffected status requirements. The SN74ALVCH162373GR operates across a lower voltage supply range (1.65V to 3.6V) compared to the original part (4.5V to 5.5V), with improved propagation delay characteristics (1ns versus 2ns) and reduced output current specifications (12mA versus 24mA). These electrical enhancements position the substitute as a direct functional replacement suitable for both legacy system maintenance and new design implementations.

Frequently Asked Questions (FAQ)
