Voltage values are with respect to network ground terminal. When the S input is pulsed low, the Q output will be set high. Normally, the S-R inputs should not be taken low si- multaneously. Questions concerning potential risk applications should be directed to Tl through a local SC sales office.

Testing and other quality control techniques are utilized to the extent Tl deems necessary to support this warranty. Inclusion of Tl products in such applications is understood to be fully at the risk of the customer.


Full text of ” IC Datasheet: Load circuits and voltage waveforms are shown in Section 1. Certain applications using semiconductor products may involve potential risks of death, personal injury, or severe property or environmental damage “Critical Applications”. 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. Tl warrants performance of its semiconductor products and related software to the specifications applicable at the time of sale in accordance with Tl’s standard warranty.

IqC is maasursd wirh alt R inputs grounded, all S inputs at 4. Pin numbers shown are for D, J, N, and W packages.

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. 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 74s279 combination, machine, or process in which such semiconductor products or services might be or are used.


When R is pulsed low, the Q output will be reset low.

Under conventional opera- tion, the S-R inputs are normally held high. Datashet the history of over billion web pages on the Internet. Ice is measured with all R inputs grounded, all S inputs at 4. The Q output will be unpredictable in this condition. 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.
