Great for workshop or maintenance spare parts
Unused old stock device from National Semi
NATIONAL SEMICONDUCTOR - Dual Comparator
Type: LM393N
A few different versions of these, I would say this is the A version (lower specs than the later B versions)
8 pin DIL plastic case
Extracted from the original datasheets...
The LM393 series are dual independent precision voltage comparators capable of single or split supply operation. These devices
are designed to permit a common mode range−to−ground level with single supply operation. Input offset voltage specifications as low as
2.0 mV make this device an excellent selection for many applications in consumer, automotive, and industrial electronics.
FEATURES:
•Wide Single−Supply Range: 2.0 Vdc to 36 Vdc
•Split−Supply Range:±1.0 Vdc to±18 Vdc
•Very Low Current Drain Independent of Supply Voltage: 0.4 mA
•Low Input Bias Current: 25 nA
•Low Input Offset Current: 5.0 nA
•Low Input Offset Voltage: 5.0 mV (max) LM293/393
•Input Common Mode Range to Ground Level
•Differential Input Voltage Range Equal to Power Supply Voltage
•Output Voltage Compatible with DTL, ECL, TTL, MOS, and CMOS
Logic Levels
•ESD Clamps on the Inputs Increase the Ruggedness of the Device
