DESCRIPTION
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.
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.

(2) Processing is per the Texas Instruments commercial production baseline and is in compliance with the Texas Instruments Quality
Control System in effect at the time of manufacture. Electrical screening consists of DC parametric and functional testing at room
temperature only. Unless otherwise specified by Texas Instruments AC performance and performance over temperature is not
warranted. Visual Inspection is performed in accordance with MIL-STD-883 Test Method 2010 Condition B at 75X minimum.
