TS555集成電路（IC）的可編程定時(shí)器振蕩器規(guī)格書PDF中文資料

TS555屬于集成電路（IC）的可編程定時(shí)器振蕩器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的TS555可編程定時(shí)器和振蕩器可以設(shè)置用來以指定頻率提供定時(shí)脈沖的器件。

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.
