Product Introduction

Overview

The TS556IDT, produced by STMicroelectronics, is a low-power dual CMOS timer that offers significant improvements over traditional bipolar timers like the NE556. This component is designed to provide very low power consumption, high frequency capabilities, and compatibility with a wide range of voltage levels. The TS556IDT is available in SO14 (Small Outline 14-pin) packages, making it suitable for various applications requiring precise timing and low power usage.

  • High Frequency Capability: Maximum astable frequency of 2.7 MHz.
  • Wide Voltage Range: Operates from 2 V to 16 V.
  • Reduced Supply Current Spikes: Minimizes the need for large decoupling capacitors.
  • High Input Impedance: 10^12 Ω, allowing for smaller timing capacitors.
  • Output Compatibility: Compatible with TTL, CMOS, and logic MOS outputs.
  • Precision Timing: Accurate timing in both monostable and astable modes, independent of supply voltage.

Applications

The TS556IDT is versatile and can be used in various applications requiring precise timing and low power consumption. Some common applications include:

  • Monostable Operation: Acts as a one-shot generator, useful in circuits that require a single pulse of a specified duration.
  • Astable Operation: Functions as a multivibrator, generating a continuous waveform with adjustable frequency and duty cycle.
  • Pulse Generation: Can be used to generate pulses for timing circuits in digital systems.
  • Power Management: Suitable for battery-powered devices due to its low power consumption.

Q & A

  1. What is the typical supply current of the TS556IDT at VCC = 5V?
    The typical supply current is 220 µA at VCC = 5V.
  2. What is the maximum astable frequency of the TS556IDT?
    The maximum astable frequency is 2.7 MHz.
  3. What is the input impedance of the TS556IDT?
    The input impedance is 10^12 Ω.
  4. Is the TS556IDT compatible with TTL and CMOS outputs?
    Yes, it is compatible with TTL, CMOS, and logic MOS outputs.
  5. How does the TS556IDT handle supply current spikes during output transitions?
    The TS556IDT reduces supply current spikes during output transitions, minimizing the need for large decoupling capacitors.
  6. What are the common operating modes of the TS556IDT?
    The TS556IDT can operate in both monostable and astable modes.
  7. How is the timing interval in the monostable mode affected by the supply voltage?
    The timing interval is independent of the supply voltage due to the proportional relationship between the charge rate and the threshold level of the comparator.
  8. What is the duty cycle formula for the astable mode of the TS556IDT?
    The duty cycle is given by D = RB / (RA + 2RB).
  9. What is the recommended action for the Reset pin when not in use?
    The Reset pin should be tied high to avoid any possible or false triggering.
  10. Is the TS556IDT still in production?
    No, the TS556IDT is obsolete and no longer manufactured.
