description
The TLC556 series are monolithic timing circuits
fabricated using the TI LinCMOS 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
a threshold level approximately two-thirds of the supply voltage. These levels can be altered by use of the control
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.
While the 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 T charges through RA and RB to the threshold voltage level (approximately 0.67
VDD) and then discharges through RB only to the value of the trigger voltage level (approximately 0.33 VDD).
The output is high during the charging cycle (tH) and low during the discharge cycle (tL). The duty cycle is
controlled by the values of RA, and RB, and CT, as shown in the equations below.

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 ron adds to RB to provide
another source of error in the calculation when RB is very low or ron is very high.
The equations below provide better agreement with measured values.

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
terms can be substituted with good results. Duty cycles less than 50% tH
tH
)
tL will require that tH
tL <1 and
possibly RA ≤ ron. These conditions can be difficult to obtain.
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.
