Pin numbers shown are for D, J, N, and W packages. 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. Search the history of over billion web pages on the Internet.

IC Datasheet: 74LS279

Tl assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or services described herein.

Questions concerning potential risk applications should be directed to Tl through a local SC sales office. Under conventional opera- tion, the S-R inputs are normally held high.


Use of Tl products in such applications requires the written approval of an appropriate Tl officer. Specific testing of all parameters of each device is not necessarily performed, except those mandated by government requirements.

When the S datahseet is pulsed low, the Q output will be set high. When R is pulsed low, the Q output will be reset low.

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. Inclusion of Tl products in such applications is understood to be fully at the risk of the customer.

The Q output will be unpredictable in this condition. Normally, the S-R inputs should not be taken low si- multaneously. Testing and other quality control techniques are utilized to the extent Tl deems necessary to support this warranty. IqC is maasursd wirh alt R inputs grounded, all S inputs at 4.

In 47ls279 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. Voltage values are with respect to network ground terminal.

Load circuits and voltage waveforms are shown in Section 1. Ice is measured with all R inputs grounded, all S inputs at 4.
