  • Manufacturer:
  • Newark Part No.: 57K3904
  • Manufacturer Part No ICM7556IPDZ

Product Overview

The ICM7556IPDZ is a CMOS RC Timer provides significantly improved performance over the standard SE/NE555/6 and 355 timers, while at the same time being direct replacements for those devices in most applications. Improved parameters include low supply current, wide operating supply voltage range, low THRESHOLD, TRIGGER and RESET currents, no crowbarring of the supply current during output transitions, higher frequency performance and no requirement to decouple control voltage for stable operation. Specifically, the ICM7556 are stable controllers capable of producing accurate time delays or frequencies. The ICM7556 is a dual ICM7555, with the two timers operating independently of each other, sharing only V+ and GND. In the one shot mode, the pulse width of each circuit is precisely controlled by one external resistor and capacitor.
  • Exact equivalent in most cases for SE/NE555/556 or TLC555/556
  • 120μA Low supply current
  • 20pA Extremely low input currents
  • 0.005%/°C at +25°C temperature stability
  • Normal reset function no crowbarring of supply during output transition
  • Can be used with higher impedance timing elements than regular 555/6 for longer RC time constants
  • Timing from microseconds through hours
  • Operates in both astable and monostable modes
  • Adjustable duty cycle
  • High output source/sink driver can drive TTL/CMOS
  • Outputs have very low offsets, HI and LO


ESD sensitive device, take proper precaution while handling the device.
