Pin numbers shown are for D, J, N, and W packages. Specific testing of all parameters of each device is not necessarily performed, except those mandated by government requirements. Tl assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or services described herein. Use of Tl products in such applications requires the written approval of an appropriate Tl officer.


Voltage values are with respect to network ground terminal.

In order to minimize risks associated with the customer’s applications, adequate design and operating safeguards should be provided by the customer to minimize inherent or procedural hazards. Load datasheer and voltage waveforms are shown in Section 1. Normally, the S-R inputs should not be taken low si- multaneously. Ice is measured with all R inputs grounded, all S inputs at 4.

When R is pulsed low, the Q output will be reset low. Certain applications using semiconductor products may involve potential risks of death, personal injury, or severe property or environmental damage “Critical Applications”. Nor does Tl warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right of Tl covering or relating to any combination, machine, or process in which such semiconductor products or services might be or are used.

Dataxheet warrants performance of its semiconductor products and related software to the specifications applicable adtasheet the time of sale in accordance with Tl’s standard warranty.

Testing and other quality control techniques are utilized to the extent Tl deems necessary to support this warranty. Under conventional opera- tion, the S-R inputs are normally held high. Questions concerning potential risk applications should be directed to Tl through a local SC sales office. S Not more than one output should be shorted at a time, and ths duration of the short-circuit should ba Iwss than one second, NOTE 2. Search the history of over billion web pages on the Internet.

Full text of ” IC Datasheet: When the S input is pulsed low, the Q output will be set high. The Q output will be unpredictable in this condition.
