- Part Models
- 6
- 1ku List Price
- Starting From $1.43
Overview
- Improved 2nd Source (See 4th Page for Maxim Advantage)
- Wide Supply Voltage Range: 2V to 18V
- No Crowbarring of Supply During Output Transition
- Adjustable Duty Cycle
- Low THRESHOLD, Active-Low TRIGGER, and Active-Low RESET Currents
- TTL Compatible
- Monolithic, Low-Power CMOS Design
The Maxim ICM7555 and ICM7556 are respectively single and dual general-purpose RC timers capable of generating accurate time delays or frequencies. The primary feature is an extremely low supply current, making this device ideal for battery-powered systems. Additional features include low THRESHOLD, active-low TRIGGER, and active-low RESET currents, a wide operating supply voltage range, and improved performance at high frequencies.
These CMOS low-power devices offer significant performance advantages over the standard 555 and 556 bipolar timers. Low-power consumption, combined with the virtually nonexistent current spike during output transitions, make these timers the optimal solution in many applications.
