Description for the TLC555
The TLC555 is a monolithic timing circuit fabricated using the TILinCMOS™ process. The timer is fully compatiblewith CMOS, TTL, and MOS logic and operates at frequencies up to 2 MHz. Because of its high inputimpedance, this device supports smaller timing capacitors than those supported by the NE555 orLM555. As a result, more accurate time delays and oscillations are possible. Power consumption islow across the full range of power-supply voltage.
Like the NE555, the TLC555 has a trigger level equal to approximately one-third of thesupply voltage and a threshold level equal to approximately two-thirds of the supply voltage. Theselevels 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 thetrigger level and the threshold input (THRES) is above the threshold level, the flip-flop is resetand the output is low. The reset input (RESET) can override all other inputs and can be used toinitiate 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 must be tied to an appropriate logic level to prevent falsetriggering.
NEW - You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.
A custom reel
is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.
Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.TI often ships
devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
