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 free-running 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
rnA or drive TTL circuits. TIming intervals from microseconds
through hours can be obtained. Additional terminals are
provided for triggering or resetting if desired.

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

MC1594L TA = -55° to +125°C, Case 620
MC1494L TA = 0° to +70°C, Case 620
The MC1594/MC1494 is a variable transconductance
multiplier with internal level-shift circuitry and voltage
regulator. Scale factor, input offsets and output offset are
completely adjustable with the use of four external
potentiometers. Two complementary regulated voltages are
provided to simplify offset adjustment and improve power
supply rejection.
MC1595L TA = -55° to +125° C, Case 632
MC1495L TA = 0° to +70° C, Case 632
These devices are designed for uses where the output is
a linear product of two input voltages. Maximum versatility is
assured by allowing the user to select the level shift method.
Typical applications include: multiply, divide(1), square root(1),
mean square(1), phase detector, frequency doubler, balanced
modulator/demodulator, and electronic gain control.
