DESCRIPTION

· The ICM7555 is a CMOS timer offering enhanced performance over the NE/SE555, serving as a direct replacement in most applications.

· It features low supply current, wide operating voltage range, and improved frequency performance without the need for CONTROL_VOLTAGE decoupling.

· Capable of precise time delays or frequencies, it operates in both one-shot and astable modes with accurate control via external resistors and capacitors.

FEATURES

· Direct replacement for NE/SE555 in most applications.

· Low supply current: 80 µA (typical).

· Extremely low trigger, threshold, and reset currents: 20 pA (typical).

· High-speed operation up to 500 kHz.

· Wide operating voltage range: 3 V to 16 V.

· No crowbarring of supply during output transitions.

· Suitable for use with higher-impedance timing elements.

· Timing range from microseconds to hours.

· Operates in astable and monostable modes with adjustable duty cycle.

· High output driver capable of driving TTL/CMOS loads.

· Excellent temperature stability: 0.005% / °C at 25°C.

· Rail-to-rail outputs.
