TS556C集成电路（IC）的可编程定时器振荡器规格书PDF中文资料

TS556C属于集成电路（IC）的可编程定时器振荡器。由意法半导体集团制造生产的TS556C可编程定时器和振荡器可以设置用来以指定频率提供定时脉冲的器件。

DESCRIPTION

The TS556 is a dual CMOS timer which offers very low consumption (Icc(TYP) TS556 = 220µA 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 (1012Ω).
