1 / 11 page 1/11 s VERY LOW POWER CONSUMPTION : 220 µA typ at VCC = 5V 180 µA typ at VCC = 3V s HIGH MAXIMUM ASTABLE FREQUENCY 2.7MHz s PIN-TO-PIN AND FUNCTIONALLY COMPATIBLE WITH BIPOLAR NE556 s WIDE VOLTAGE RANGE : +2V to +16V s HIGH OUTPUT CURRENT CAPABILITY s SUPPLY CURRENT SPIKES REDUCED DURING OUTPUT TRANSITIONS s HIGH INPUT IMPEDANCE : 1012 Ω s OUTPUT COMPATIBLE WITH TTL,CMOS AND LOGIC MOS DESCRIPTION The TS556 is a dual CMOS timer which offers very low consumption (I cc(TYP) TS556 = 220µA at VCC=+5V versus Icc(TYP) NE556 = 6mA) and high frequency f f(max.) TS556 = 2.7MHz versus f (max. ) NE556 = 0.1 MHz) Thus, either in Monostable or Astable mode, tim- ing remains very accurate. The TS556 provides reduced supply current spikes during output transitions, which enables the use of lower decoupling capacitors compared to those required by bipolar NE556. Timing capacitors can also be minimized due to high input impedance (1012 Ω).
