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 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 Four±Quadrant 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.

MC1494P
TA = 0° to +70°C, Case 648
This device has all the necessary internal regulation and references. The single±ended output is referenced to ground.
MC1495D, P
TA = 0° to +70°C, Case 751A, 646
Maximum versatility is assured by allowing the user to select the level shift method.
MC1495BP
TA = ±40° to +125°C, Case 646
Linearity and offset are actually tested over temperature. This is an improved specification over previous versions.
