The TLC556 series are monolithic timing circuits  
fabricatedusingtheTILinCMOS process, which  
provides full compatibility with CMOS, TTL, and  
MOS logic and operates at frequencies up to  
2 MHz. Accurate time delays and oscillations are  
possible with smaller, less-expensive timing  
capacitors than the NE556 because of the high  
input impedance. Power consumption is low  
across the full range of power supply voltages.

Like the NE556, the TLC556 has a trigger level  
approximately one-third of the supply voltage and  
athresholdlevelapproximatelytwo-thirdsofthesupplyvoltage. Theselevelscanbealteredbyuseofthecontrol  
voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set and the output goes high.  
If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is  
reset and the output is low. The reset input can override all other inputs and can be used to initiate a new timing  
cycle. If the reset input is low, the flip-flop is reset and the output is low. Whenever the output is low, a  
low-impedance path is provided between the discharge terminal and ground.  
Whilethe CMOS output is capable of sinking over 100 mA and sourcing over 10 mA, the TLC556 exhibits greatly  
reduced supply-current spikes during output transitions. This minimizes the need for the large decoupling  
capacitors required by the NE556.  
These devices have internal electrostatic-discharge (ESD) protection circuits that prevent catastrophic failures  
at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015. However, care should be exercised in  
handling these devices, as exposure to ESD may result in degradation of the device parametric performance.  
All unused inputs should be tied to an appropriate logic level to prevent false triggering.  
The TLC556C is characterized for operation from 0°C to 70°C. The TLC556I is characterized for operation from  
40°C to 85°C. The TLC556M is characterized for operation over the full military temperature range of 55°C  
to 125°C.

Figure 3. Astable Operation  
Connecting the trigger input to the threshold input, as shown in Figure 3, causes the timer to run as a  
multivibrator. The capacitor C charges through R and R to the threshold voltage level (approximately 0.67

) and then discharges through R only to the value of the trigger voltage level (approximately 0.33 V ).

The 0.1-µF capacitor at CONT in Figure 3 decreases the period by about 10%.  
The formulas shown above do not allow for any propagation delay from the trigger and threshold inputs to the  
discharge output. These delay times add directly to the period and create differences between calculated and  
actual values that increase with frequency. In addition, the discharge output resistance r adds to R to provide  
on  
B
another source of error in the calculation when R is very low or r is very high.

APPLICATION INFORMATION  
The preceding equations and those given earlier are similar in that a time constant is multiplied by the logarithm  
of a number or function. The limit values of the logarithmic terms must be between In 2 at low frequencies and  
In 3 at extremely high frequencies. For a duty cycle close to 50%, an appropriate constant for the logarithmic

In monostable applications, the trip point of the trigger input can be set by a voltage applied to CONT. An input  
voltage between 10% and 80% of the supply voltage from a resistor divider with at least 500-µA bias provides  
good results.

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other  
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest  
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and  
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale  
supplied at the time of order acknowledgment.  
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms  
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary  
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily  
performed.  
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and  
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or  
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information  
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or  
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the  
third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration  
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered  
documentation. Information of third parties may be subject to additional restrictions.  
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service

requirements. Nonetheless, such components are subject to these terms.  
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties  
have executed a special agreement specifically governing such use.  
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in  
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components  
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and  
regulatory requirements in connection with such use.  
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of  
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
