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 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
A.
Supply voltage range: from 2.0 to 18V.
Input current: 50, 100 pA at T=25
.
Output current: 20 mA.
Timing from microseconds to hours.
Operates both in astable and monostable modes.
Adjustable duty cycle.
Temperature stability: 0.06%/
.
Latch current not less than 100 mA at T=70
.
Allowed static potential value: not less than 2000V (HBM) and not less than 200 V ().
