Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC1G99DCTRG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: Configurable Multiple Function
• Number of Circuits: 1
• Number of Inputs: 4
• Output Type: Tri-State
• Current - Output High, Low: 32mA, 32mA
• Voltage - Supply: 1.65V ~ 5.5V
• Operating Temperature: -40°C ~ 125°C
• Package / Case: 8-LSSOP, 8-MSOP (0.110", 2.80mm Width)
• Supplier Device Package: SM8

The SN74LVC1G99DCTR meets all substitution criteria. This part shares identical electrical specifications, functional configuration, and physical packaging with the discontinued SN74LVC1G99DCTRG4. The primary difference is packaging format: the substitute is supplied in Tape & Reel (TR) configuration rather than the original packaging designation.
