STMicroelectronics TS556CDT

Standard Timer Dual 14-Pin SOIC T/R

IC OSC TIMER DUAL 2.7MHZ 14-SOIC

The TS556 is a dual CMOS timer which offers very low consumption (I cc(TYP) TS556 = 220uA at V CC=+5V versus I cc(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 tohigh input impedance (1012\Omega ).
