DESCRIPTION/ORDERING INFORMATION
The TLC555 is a monolithic timing circuit fabricated using the TI LinCMOS process. The timer is fully
compatible with CMOS, TTL, and MOS logic and operates at frequencies up to 2 MHz. 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.

Functionally Interchangeable With the NE555;
Has Same Pinout
Like the NE555, the TLC555 has a trigger level equal to approximately one-third of the supply voltage and a
threshold level equal to approximately two-thirds of the supply voltage. These levels can be altered by use of the
control voltage terminal (CONT). When the trigger input (TRIG) falls below the trigger level, the flip-flop is set
and the output goes high. If TRIG is above the trigger level and the threshold input (THRES) is above the
threshold level, the flip-flop is reset and the output is low. The reset input (RESET) can override all other inputs
and can be used to initiate a new timing cycle. If RESET 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 (DISCH) and
GND. All unused inputs should be tied to an appropriate logic level to prevent false triggering.
While the CMOS output is capable of sinking over 100 mA and sourcing over 10 mA, the TLC555 exhibits
greatly reduced supply-current spikes during output transitions. This minimizes the need for the large decoupling
capacitors required by the NE555.
The TLC555 is characterized for operation over the full automotive temperature range of –40
