74F399 is an 8-input multiplexer logic circuit developed by Fairchild Semiconductor with the F suffix standing for fast Schottky, a type of diode used in integrated circuits. It is part of the F-family of devices, which are CMOS-based integrated circuit versions of many of the same circuits available in TTL (transistor-transistor-logic) versions.

The 74F399 multiplexer allows data from up to 8 inputs to be serialized and routed to just one output. It is a simple, versatile, and economical choice for analog and digital multiplexing of signals and is widely used in the automotive, computer, and telecommunications industries for switching and multiplexing of different kinds of signals.

The main features of the 74F399 are its fast switching time, low-power CMOS structure, and wide supply voltage range. This allows users to optimally benefit from lower power consumption while achieving shorter propagation delays. Additionally, the 74F399 operates over a wide temperature range in excess of -55°C to 125°C.

The 74F399 is available in a 16-pin dual-in-line package (DIP) or plastic leaded chip carrier (PLCC) with the dual-pole 4-position switch integrated circuits (IC) mounted inside. It is also available in various speed grades, in both 8V (Volt) and 10V versions, with an operating voltage range up to 10V.

The 74F399 multiplexers are typically used in applications such as multiplexing of serial and parallel data, a/d (analog to digital) and d/a (digital to analog) converters, logic gates, and comparators. They can also be used for multiplexing and selecting of signals from multiple sources and routing to multiple destinations. Additionally, the multiplexers are part of a wide range of local and global telecommunications switching equipment.

The 74F399 CMOS multiplexer operates on the principle of digital data switching where the input signals are obtained from the source and are transmitted through the output to the destination. Each data input line is connected to one of the 74F399’\'s 8 inputs. By applying a control signal to the multiplexer control input, the desired input is selected and sent to the output. The control circuit is responsible for turning on the desired path to transfer the data through the output pin.

The 74F399 multiplexer is an extremely versatile and cost-effective application field that is used in the analog and digital switching and multiplexing of signals at both the local and global level. It is renowned for its low-power CMOS structure, fast switching times, wide supply voltage range, and wide temperature range. Additionally, it is available in a 16-pin dual-in-line package (DIP) or plastic leaded chip carrier (PLCC) with the dual-pole 4-position switch integrated circuits (IC) mounted inside, with various speed grades and operating voltage range up to 10V. The 74F399 multiplexer is an excellent choicee for applications that require high-speed signal multiplexing.
