TS556 LOW POWER DUAL CMOS TIMER s VERY LOW POWER CONSUMPTION : s s s s s s s 220 A typ at VCC = 5V 180 A typ at VCC = 3V HIGH MAXIMUM ASTABLE FREQUENCY 2.7MHz PIN-TO-PIN AND FUNCTIONALLY COMPATIBLE WITH BIPOLAR NE556 WIDE VOLTAGE RANGE : +2V to +16V HIGH OUTPUT CURRENT CAPABILITY SUPPLY CURRENT SPIKES REDUCED DURING OUTPUT TRANSITIONS HIGH INPUT IMPEDANCE : 1012 OUTPUT COMPATIBLE WITH TTL,CMOS AND LOGIC MOS N DIP14 (Plastic Package) DESCRIPTION The TS556 is a dual CMOS timer which offers very low consumption (Icc(TYP) TS556 = 220A at VCC=+5V versus Icc(TYP) NE556 = 6mA) and high frequency ff(max.) TS556 = 2.7MHz versus f(max.) NE556 = 0.1 MHz) Thus, either in Monostable or Astable mode, timing 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).
