Transistor-Transistor Logic (TTL) Logic Latches

1450079 [SN74LS279AN from Texas Instruments Standard Linear and Logic]
from RS Components, Ltd.

Texas Instruments range of Flip-Flops and Latches from the 74LS Family of Low Power Schottky Logic ICs. The 74LS Family use bipolar junction technology coupled with Schottky diode clamps to achieve operating speeds equal to the original 74TTL family but with much lower power consumption. Logic...
