Fairchild Semiconductor 74LS Series Datasheets. DM74LS, 74LS Datasheet.

Search the history of over billion web pages on the Internet. Full text of ” IC Datasheet: Under conventional opera- tion, the S-R inputs are dataasheet held high. When the S input is pulsed low, the Q output will be set high. When R is pulsed low, the Q output will be reset low. Normally, the S-R inputs should not be taken low si- multaneously.

The Q output will be unpredictable in this condition. Pin numbers shown are for D, J, N, and W packages. Voltage values are with respect to network ground terminal.


IqC is maasursd wirh alt R inputs grounded, all S inputs at 4.

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