ICM7555IN PHILIPS [NXP Semiconductors], ICM7555IN Datasheet - Page 3

• Manufacturer Part Number: ICM7555IN
• Description: General purpose CMOS timer
• Manufacturer: PHILIPS [NXP Semiconductors]

1. The supply current value is essentially independent of the TRIGGER, THRESHOLD, and RESET voltages.
2. Astable timing is calculated using the following equation: f =
3. Parameter is not 100% tested.
