The 74LS352 is a very high-speed Dual 4-input Multiplexer with Common Select inputs and individual enable inputs for each section. It can select two bits of data from four sources. The two buffered outputs present data in the inverted (complementary) form. The IC is designed to operate over a temperature range of 0 to 70°C. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers. The IC also constitutes a wide array of features such as thermal overload protection & ESD protection. The IC 74LS352 is smaller in size and it has a much faster speed which makes it reliable in every kind of device.
What is a Multiplexer?
A multiplexer is a combinational logic circuit that switches one of several input lines to a single common output line. The select lines determine which input is connected to the output, and also to increase the amount of data that can be sent over a network within a certain time. It is also called a data selector.
