The TLC552 is a dual monolithic timing circuit  
fabricated using TI LinCMOS process, which  
provides full compatibility with CMOS, TTL, and  
MOS logic and operation at frequencies up to  
2 MHz. 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.

TRIG can override THRES.  
Like the NE556, the TLC552 has a trigger level  
approximately one-third of the supply voltage and  
a threshold level approximately two-thirds of the  
supplyvoltage. Theselevelscanbealteredbyuse  
of the control voltage terminal. When the trigger  
input falls below the trigger level, the flip-flop is set  
and the output goes high. If the trigger input is  
above the trigger level and the threshold input is  
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.  
Whilethe 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.

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.

ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in  
a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check  
http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and  
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS  
compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
