Substitute Part Grouping Explanation

Substitution for the SN74HC377NG4 is determined by strict equivalence across the following critical parameters:

• Logic Function: D-Type flip-flop with 1 element, 8-bit configuration
• Trigger Mechanism: Positive edge triggering
• Output Configuration: Non-inverted output
• Electrical Performance: Clock frequency of 64 MHz, propagation delay of 27ns @ 6V with 50pF load
• Supply Voltage Range: 2V to 6V operation
• Output Current Capability: 5.2mA source and sink current
• Package Format: 20-DIP through-hole package (0.300", 7.62mm)
• Compliance Standards: ROHS3 compliant, REACH unaffected

The SN74HC377N qualifies as a direct substitute based on identical electrical specifications, functional characteristics, and package configuration. The primary distinction is product status and packaging format (tube vs. standard packaging).
