TS555CN Datasheet Low-power Single CMOS Timer

Manufacturer: STMicroelectronics

Overview: TS555 Low-power single CMOS timer SO8 (plastic micropackage) Pin connections (top view) *1'  7ULJJHU  2XWSXW  5HVHW   9&&  'LVFKDUJH  7KUHVKROG  &RQWURO.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TS555 is a single CMOS timer with very low consumption: I(cIccc(T(TYYPP) )NTES555555(a=) 110 µA at = 3 mA), VCC = +5 V versus and high frequency: (f(fmf(maxa)xN.) TES55555(5a)==20.7.1MMHHzzv).ersus 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 pared to those required by bipolar NE555(a).

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

Key Features

  • Very low power consumption:.
  • 110 µA typ at VCC = 5 V.
  • 90 µa typ at VCC = 3 V.
  • High maximum astable frequency of 2.7 MHz.
  • Pin-to-pin functionally-compatible with bipolar NE555(a).
  • Wide voltage range: +2 V to +16 V.
  • Supply current spikes reduced during output transitions.
  • High input impedance: 1012 Ω.
  • Output compatible with TTL, CMOS and logic MOS Datasheet - production data.
