Accurate time delays and oscillations are possible with smaller, less-expensive timing capacitors than the NE555 because of the high input impedance. Power consumption is low across the full range of power supply voltages. R TRIG R DSCH GND RESET can override TRIG and THRES. TRIG can override THRES. Like the NE556, the TLC552 has a trigger level AVAILABLE OPTIONS approximately one-third of the supply voltage and SYMBOLIZATION a threshold level approximately two-thirds of the OPERATING VT max TEMPERATURE PACKAGE supply voltage. These levels can be altered by use DEVICE at 25°C RANGE SUFFIX of the control voltage terminal. When the trigger TLC552C D,N 0°C to 70°C 3.8 mV input falls below the trigger level, the flip-flop is set and the output goes high. If the trigger input is The D packages are available taped and reeled. Add the suffix R above the trigger level and the threshold input is to the device type when ordering (i.e., TLC552CDR). 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. While the CMOS output is capable of sinking over 100 mA and sourcing over 10 mA, the TLC552 exhibits greatly reduced supply-current spikes during output transitions. This minimizes the need for the large decoupling capacitors required by the NE556. LinCMOS is a trademark of Texas Instruments Incorporated.

POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 1 TLC552C DUAL LINCMOS TIMER SLFS046 – FEBRUARY 1984 – REVISED MAY 1988 description (continued) These devices have internal electrostatic discharge (ESD) protection circuits that will prevent catastrophic failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3105.2. However, care should be exercised in handling these devices as exposure to ESD may result in a degradation of the device parametric performance. All unused inputs should be tied to an appropriate logic level to prevent false triggering. The TLC552C is characterized for operation from 0°C to 70°C.
