Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only

and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification

is not implied. Exposure to absolute maximum rating conditions for external periods may affect device reliability.

* All voltage values are referred to VSS pin voltage.

pulse one period) on the application of each new

trigger pulse. For operation in the non-triggerable

mode, Q is connected to –TR when leading-edge

triggering (+ TR) is used or Q is connected to + TR

when trailing-edge triggering (– TR) is used. The time

period (T) for this multivibrator can be approximated

by TX = 1/2 RX CX for CX

≥ 0.01 µF. Time periods as

a function of RX for values of CX and VDD are given in

fig. 8. Values of T vary from unit to unit and as a func-

tion of voltage, temperature, and RX CX. The minimum

value of external resistance, RX,is 5 k

Ω. The maxi-

mum value of external capacitance, CX, is 100

µF.

Fig.9 shows time periods as a function of CX forvalues

of RX and VDD. The output pulse width has vari-

ations of

±2.5%typically, over the temperature range

of – 55

°C to 125° Cfor CX = 1000pF and RX = 100

Ω. For power supply variations of ± 5%, the output

pulse width has variations of

± 0.5% typically, for VDD

= 10V and 15V and

± 1% typically, for VDD =5 V at

CX = 1000 pF and RX =5k

Ω.
