The 1 MHz gain-bandwidth product sets the usable closed-loop bandwidth.
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.
The MC3403DT uses the standard 14-SOIC quad op-amp pinout: output 1 (pin 1), inverting input 1 (2), non-inverting input 1 (3), V+ (4), non-inverting input 2 (5), inverting input 2 (6), output 2 (7), output 3 (8), inverting input 3 (9), non-inverting input 3 (10), V- (11), non-inverting input 4 (12), inverting input 4 (13), output 4 (14). This matches the LM324 and MC3303DT.
Yes, the MC3403DT is pin-compatible with the LM324 in the same 14-SOIC footprint. 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.
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. If your board sees outdoor or unheated ambient, the MC3303DT is the safer choice.
