Search the history of over billion web pages on the Internet. Full text of ” IC Datasheet: The basic pulse datashet is programmed by selection of external resistance and capacitance values see typical application data. The ‘1 22 and ‘LSI 22 have internal timing resistors that allow the circuits to be used with only an external capacitor, if so desired.

Once triggered, the basic pulse duration may be extended by retriggering the gated low-level-active A or high-level-active B datashset, or be reduced by use of the overriding clear. Figure 1 illustrates pulse control by retriggering and early clear. The Rjnt in nominall 10 kQ for ‘ and ‘LS Texas Products conform to specifications per the terms of Texas Instruments A standard warranty.

Production processing does not necessarily include vl’V testing of all parameters. Retrigger pulses starting before 0. Voltage values are with respect to network ground terminal. R n of is open.

Ice is measured in the triggered state with 2. Load circuits and voltage waveforms are shown in Section 1.

With all outputs open and 4. Iqc is measured after a momentary ground, then 4. Tine output pulse duration is primarily a function of the external capacitor and resistor. Cext is in pF tw is in ns To prevent reverse voltage across Cext- it is recommended that the method shown in Figure 2 be employed when using electrolytic capacitors and in applications utilizing the clear function. In all applications using the diode, the dafasheet duration is: Any silicon switching diode such as 1 N or equivalent.

Applications requiring more precise pulse durations up to 28 seconds and not requiring the clear dataeheet can best be satisfied with the ‘1 Due to the timing scheme used by the ‘LSI 22 and ‘LSI 23, a switching diode is not required to prevent reverse biasing when using electolytic capacitors. Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete.
