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. 1 TRIG GND NC 2 TRIG 2 OUT 1 CONT NC 1 RESET NC 1 OUT 3 2 1 20 19 4 18 5 17 6 16 7 15 8 14 9 10 11 12 13 2 THRES NC 2 CONT NC 2 RESET Like the NE556, the TLC556 has a trigger level NC–No internal connection approximately one-third of the supply voltage and a threshold level approximately two-thirds of the supply voltage.
