GENERAL PURPOSE DUAL TIMER
ILC556N is designed to be used: as high-precision pulse oscillator 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.
In astable mode the pulse width of each circuit is controlled by
one 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.

Unlike bipolar timer, CONTROL VOLTAGE output does not
require any capacitor decoupling. TRIGGER, RESET inputs are
T_A = -20° to 70° C
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).
