Comparator IC with 4 circuits in the former National Semiconductor (current TI). A standard comparator IC with the reliable LM2901. The circuit symbol is the same as the OP amplifier LM324, but it cannot work linear with negative feedback (NFB). The OP Amplifier LM324 can also be used as a comparator, but the dedicated LM339 will be much faster. The output of the LM339 is an open collector type, so it can be used for special purposes such as wire OR/AND, level conversion etc. Specifications: Package: DIP14; Number of Circuits: 4 Circuits; Power Supply Voltage: +2 V to +36 V; Power Current: 0.8 mA (Vcc=+5 V); TPD: 1.3 μs; Output Current: O.C; Input Offset Voltage Type: 2 mV; Operating Temperature: 0 °C to +70 °C; Note:
