Description

The TLC556 series are monolithic timing circuits fabricated using the TI LinCMOSTM process, which provides full compatibility with CMOS, TTL, and MOS logic and operates at frequencies up to 2MHz. Accurate time delays and oscillations are possible with smaller, less-expensive timing capacitors than the NE556 because of the high input impedance. Power consumption is low across the full range of power supply voltages.

Like the NE556, the TLC556 has a trigger level approximately one-third of the supply voltage and

a threshold level approximately two-thirds of the supply voltage. These levels can be altered by use of the control voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set and the output goes high.
