General purpose dual timer

with adjustable frequency and on-off time ratio; for producing accurate

time delays using external resistors and capacitors; as a timer in

domestic appliances, in measuring equipment, computers; as functional

units in electronic instruments. The timer may be used as oscillator

producing accurate time delays and frequencies.

external resistor and capacitor. In monostable mode, when used as

oscillator, its own frequency of oscillation and on-off time ratio are

controlled by two external resistors and one capacitor.

require any capacitor decoupling. TRIGGER, RESET inputs are active

as per low level. Output inverter provides sufficient drain and source

currents to control TTL-loads, and provides minimum bias when

controlling CMOS-loads. Input voltage levels are compatible with

standard CMOS levels.

• Output voltage levels are compatible with input levels of CMOS ICs.

• Supply current: not more than 600 µA.

• Supply voltage range: from 2.0 to 18V.

• Input current: 50, 100 pA at T=25 °С.

• Output current: 20 mA.

• Timing from microseconds to hours.

• Operates both in astable and monostable modes.

• Adjustable duty cycle.

• Temperature stability: 0.06%/°С.

• Latch current not less than 100 mA at T=70 °С.

• Allowed static potential value: not less than 2000V (HBM) and not less than 200 V (ММ).

ILC556N/D is designed to be used: as high-precision pulse oscillator

In astable mode the pulse width of each circuit is controlled by one

Unlike bipolar timer, CONTROL VOLTAGE output does not
