Product Introduction

Overview

The ICM7555CD,623 is a general-purpose CMOS timer produced by NXP USA Inc. It offers significantly improved performance compared to the standard NE/SE555 timer and is designed to be a direct replacement for those devices in most applications. This timer is known for its low supply current, wide operating supply voltage range, and high frequency performance. It operates in both astable and monostable modes, making it versatile for various timing and clock generation functions.

Key Features

  • Low Supply Current: The ICM7555CD,623 operates with a low supply current, typically 180 µA at VDD = Vmax.
  • Wide Operating Supply Voltage Range: It can operate within a supply voltage range of 3 V to 16 V.
  • High Frequency Performance: The timer can generate frequencies up to 500 kHz.
  • No Crowbarring of Supply Current: Unlike the NE/SE555, it does not produce large crowbar currents during output transitions, eliminating the need for supply decoupling in most cases.
  • Adjustable Duty Cycle: It supports adjustable duty cycle in astable mode.
  • High Output Source/Sink Driver: Capable of driving TTL/CMOS loads.
  • Rail-to-Rail Outputs: Provides rail-to-rail output signals.
  • Temperature Stability: Offers a typical temperature stability of 0.005 % / °C at 25 °C.

Applications

  • Automotive Control: Used in automotive engine control, transmission control, and timing functions for generating precise ignition timing in internal combustion engines.
  • Industrial Automation: Synchronizes processes, controls machinery, and coordinates the timing of various operations.
  • Digital Signal Processing (DSP): Used for scheduling and timing the execution of specific signal-processing tasks, providing accurate clock signals for maintaining signal integrity.
  • Aerospace and Defense: Coordinates and synchronizes various aircraft, radar, and central control systems.
  • Precision Timing: Ideal for precision timing, pulse generation, sequential timing, time delay generation, pulse width modulation, and pulse position modulation.
