Other analog circuits are provided for special
applications with both bipolar and CMOS technologies.
These circuits range from the industry standard analog
timing circuits and multipliers to specialized CMOS smoke
detectors. These products provide key functions in a wide
range of applications, including data transmission,
commercial smoke detectors, and various industrial
controls.

Timing Circuits
These highly stable timers are capable of producing
accurate time delays or oscillation. In the time delay mode of
operation, the time is precisely controlled by one external
resistor and capacitor. For a stable operation as an oscillator,
the freerunning frequency and the duty cycle are both
accurately controlled with two external resistors and one
capacitor. The output structure can source or sink up to 200 mA
or drive TTL circuits. Timing intervals from microseconds
through hours can be obtained. Additional terminals are
provided for triggering or resetting if desired.

Multipliers
Linear FourQuadrant Multipliers
Multipliers are designed for use where the output voltage is
a linear product of two input voltages. Typical applications
include: multiply, divide, square, rootmeansquare, phase
detector, frequency doubler, balanced modulator/demodulator,
electronic gain control.

Smoke Detectors (CMOS)
These smoke detector ICs require a minimum number of
external components. When smoke is sensed, or a low battery
voltage is detected, an alarm is sounded via an external
piezoelectric transducer. All devices are designed to comply
with UL specifications.
