Tesar The are triggered and reset on falling negative waveforms, and the output inverter can source or sink currents large enough to drive TTL loads, or provide minimal offsets to drive CMOS loads. In case of conflict between Datasheef and Metric dimensions, the inch dimensions control. These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

At a supply voltage of 4. Initially the external capacitor C is held discharged by a transistor inside the timer. Dambar protrusions shall not exceed 0. At all supply voltages it represents an extremely high input impedance. This avoids the multiple threshold problems sometimes encountered with slow falling edges in the bipolar devices. The timer can also be connected as shown in Figure 2B.

For this reason it is recommended that no inputs from external sources not operating from the same power supply be applied to the device datasheeet its power supply dstasheet established. Guaranteed Supply Voltage Range. E and eA are measured with the leads constrained to be perpendicular to datum -C.

Datasbeet functional diagram reduces the circuitry down to its simplest equivalent components. This provides the possibility of oscillation frequency modulation in the astable mode or even inhibition of oscillation, depending on the applied voltage. In the one shot mode, the pulse width of each circuit is precisely controlled by one external resistor and capacitor. Trip points and output swings are symmetrical. For astable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled by two external resistors and one capacitor.

In this circuit, the frequency is: If it is not present, a visual index feature must be located within the crosshatched area. Interlead flash and protrusions shall not exceed 0.

As such, if driving CMOS, the output swing at all supply voltages will equal the supply voltage. Extremely Low Input Currents. They are not intended for use in Reflow solder processing applications. Tie down unused inputs. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

B1 maximum dimensions do not include dambar protrusions. Converted inch dimensions are not necessarily exact. These parameters are based upon characterization data and are not tested.
