description

GND

DISCH

THRES

The TLC555 is a monolithic timing circuit

TRIG

OUT

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.

RESET

CONT

NC − No internal connection

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.
