TS555I集成电路（IC）的可编程定时器振荡器规格书PDF中文资料

TS555I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TS555I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 TS555 is a single CMOS timer with a very low consumption:

(Icc(TYP) TS555 = 110 µA at VCC = +5 V versus Icc(TYP)NE555 = 3 mA),

and high frequency:

(ff(max.) TS555 = 2.7 MHz versus

f(max) NE555 = 0.1 MHz).

Timing remains accurate in both monostable and astable mode.

The TS555 provides reduced supply current spikes during output transitions, which enable the use of lower decoupling capacitors compared to those required by bipolar NE555.

With the high input impedance (1012Ω), timing capacitors can also be minimized.
