Description

ICM7556IPD is general-purpose RC timer IC. 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, TRIGGER, and 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.

Features

● 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, TRIGGER, and RESET Currents

● TTL Compatible

● Monolithic, Low-Power CMOS Design

NE555 Timer

Description

The NE555, SA555, and SE555 monolithic timing circuits are highly stable controllers capable of producing accurate time delays or oscillation. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For a stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200 mA.

The NE555 Timer IC is a popular timer integrated circuit (IC) that can be used to generate precise time delays, oscillations, and pulse-width modulation (PWM) signals. The NE555 is a monolithic timing circuit that contains a precision timing section, an adjustable voltage divider, and a temperature-compensated reference.
