Frequently Asked Questions
What is the recommended power supply voltage range for these comparators?
The maximum ratings require a Power Supply Voltage (V) of +36 or ±18 Vdc.
Are these components compatible with TTL and CMOS logic?
Yes, they are listed as both TTL and CMOS Compatible.
What is the safe output state regarding short circuits?
Short circuiting the Output to Ground (Note 1) is continuous up to 20 mA. Short circuits to V can cause excessive heating.
Which product supports the highest operating temperature range?
The LM2901V and LM339A/LM239A series support temperatures down to -40°C, with the LM2901V going up to +125°C (Note 3).
What is the typical input bias current for reliable operation?
The Input Bias Current (IB) is typically listed as 25-250 nA.
