Product Summary

Your source for precision timers.

The TLC555/TLC555CP is a monolithic timing circuit. The timer is fully compatible with CMOS, TTL and MOS logic and operates at frequencies up to 2MHz. Because of its high input impedance, this device uses smaller timing capacitors than those used by the NE555. As a result, more accurate time delays and oscillations are possible. Power consumption is low across the full range of power supply voltage.

Like the NE555, the TLC555 has a trigger level of approximately one-third of the supply voltage and a threshold level equal approximately to two-thirds of the supply voltage. These levels can be altered by use of the control voltage terminal (CONT).

  • Fully compatible with CMOS, TTL and MOS logic
  • Operates at frequencies up to 2 MHz

      Inadequate Data

      By Bobdi

      Verified Reviewer

      Comments about RadioShack TLC555/TLC555CP LinCMOS Timer (8-Pin DIP):

      The data provided by RS is inacceptable. There are no voltage or power limits shown, which are basic.

              With two resistors and a capacitor, this timer makes a simple and efficient low speed clock. Great for testing A/D converters. Because it's a CMOS part, it is compatible with +3.3V supplies.

                Very good multipurpose chip. Texas Instruments makes a great 555 timer IC. Motorola's MC1455 is the ONLY better chip on the open-market. I will keep on getting these in the future.

                I use these chips in
                1. Siren oscillator.
                2. Astable timer (for Attack mode)
                3. One-shot stable timer (for alert)
                4. LED flasher
                5. Tone generator (see siren note above)
                6. DC-AC inverter (yes it is possible to use one, in conjunction with a MOSFeT and a 2N3055, as well as about a dozen other [common] parts to invert DC to AC)

                  can be used as a replacement for the LM555 as they are pin compatible, This has lower power requirements then other 555 timers. This IC is made by TI. Used it in a astable circuit, and is on the dot accurate. Used 5% tolerance resistors and a Tantalum capacitor (272-1434) for the timing circuit.
