Frequently Asked Questions
What output type does the LM339N use?
Open-collector. An external pull-up resistor is required to define the high output logic level. Verify pull-up requirements against your circuit datasheet before use.
Is this a through-hole or surface-mount package?
Through-hole — 14-pin DIP (PDIP). Not compatible with surface-mount footprints.
What logic families is the LM339N compatible with?
The research notes confirm CMOS and MOS compatibility. Additional logic family compatibility is not confirmed — verify against the manufacturer datasheet before use.
Is this part new or used?
Unused NOS — new old stock. These units have not been installed or soldered. Visual inspection confirmed no issues.
