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.

NC–No internal connection

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.
