Substitute Part Grouping Explanation

Substitution of the SN74LS14DRG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: Inverter with Schmitt trigger functionality
• Number of Circuits: 6 channels
• Number of Inputs: 1 input per circuit
• Voltage - Supply: 4.75V ~ 5.25V operating range
• Current - Output High, Low: 400µA, 8mA specifications
• Input Logic Level - Low: 0.5V threshold
• Input Logic Level - High: 1.9V threshold
• Max Propagation Delay: 22ns @ 5V, 15pF load
• Operating Temperature: 0°C ~ 70°C range
• Package / Case: 14-SOIC form factor
• Mounting Type: Surface Mount

The SN74LS14DR meets all specified parameters and serves as a parametric equivalent. Substitution is valid when all electrical characteristics and package specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

The SN74LS14DR is the direct parametric equivalent for the discontinued SN74LS14DRG4. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications across all critical parameters including logic function, voltage supply range, output current ratings, input thresholds, propagation delay, and operating temperature range.

The primary distinction is product status: the SN74LS14DRG4 is discontinued at DiGi Electronics, while the SN74LS14DR maintains active status with higher inventory availability (2900 Pcs vs. 794 Pcs). Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The SN74LS14DR is suitable for direct substitution in applications currently using the SN74LS14DRG4, with no circuit redesign or board layout modifications required due to identical 14-SOIC packaging and electrical performance.
