Substitute Part Grouping Explanation

Substitution of the SN74LS375DRG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 1:1 ratio with 4 independent channels
• Output Type: Differential
• Supply Voltage Range: 4.75V ~ 5.25V
• Propagation Delay: 12ns
• Output Current Specifications: 400µA (high), 8mA (low)
• Operating Temperature Range: 0°C ~ 70°C
• Package Type: 16-SOIC surface mount
• Base Product Number: 74LS375

The SN74LS375D qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format, with the substitute part currently in active production status.
