TS556

Low-power dual CMOS timer

Datasheet

- production data

Features

• Very low power consumption:

– 220 µA typ at VCC = 5 V

– 180 µA typ at VCC = 3 V

• High maximum astable frequency 2.7 MHz

• Pin-to-pin and functionally compatible with

bipolar NE556(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

Description

The TS556 is a dual CMOS timer which offers a

very low consumption:

(Icc(TYP) TS556 = 220 µA at VCC = 5 V versus

Icc(TYP) NE556

(a) = 6 mA),

and high frequency:

(f(max.) TS556 = 2.7 MHz versus

f(max.) NE556

(a) = 0.1 MHz)

In both monostable and astable modes, 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(a).

Due to the high input impedance (1012

Ω), timing

capacitors can also be minimized.
