The 0.5 V/µs slew rate limits large-signal response. ## Commercial temperature grade — indoor use only The 0°C to 70°C range limits deployment to heated indoor environments. For motor drives, outdoor telecom, or automotive cabin applications, the MC3303DT extends to -40°C to 105°C while maintaining the same 1 MHz GBW, 0.5 V/µs slew rate, and 40 nA input bias. The MC3403DT is active and ROHS3 compliant. No end-of-life notification is recorded.

Electrical parameters are similar: 1 MHz GBW, 0.5 V/µs slew rate, 1 mV offset. The main difference is the 0°C to 70°C temperature range versus the LM324's typical -40°C to 85°C range, so verify the ambient conditions of your application."},{"question":"What is the difference between MC3403DT and MC3303DT?","answer":"The MC3303DT is the industrial-temperature version of the same quad op-amp, rated -40°C to 105°C versus the MC3403DT's 0°C to 70°C. All other key specs are identical: 1 MHz GBW, 0.5 V/µs slew rate, 40 nA input bias, 1 mV offset, 30 mA output, same 14-SOIC pinout.
