The IDT72V71623BC8 is an integrated circuit that functions as an electronic switch. It acts as a high-speed non-blocking simultaneous three-way multiplexer and decoder, available with outputs in both bipolar and CMOS technology.

The IDT72V71623BC8 is a highly flexible switch. Operation is based on logic levels and a high degree of speed that is suitable for switching digital signals. It performs a variety of tasks, from encoding and decoding multiplexed signals to bridge or connect signals to their respective address lines, with the aptitude for quickly and accurately responding to inputs.

This switch operates with a positive, true logic level of 1.67 to 6.8V. Input impedances can range between 26Ω to 78Ω. The max current loading is 8mA, power dissipation is 1.1W and the maximum propagation delay is 0.55ns.

The IDT72V71623BC8 features individual input enable and output enable controls. These controls provide flexibility in the multiplexing of logic signals in different types of application. The designing of a single chip device makes it appealing to many applications including those where the physical space is limited. This device provides short switching times with the use of high-speed output stages that can provide uniform step delay and give performance enhancement needed for current high-speed systems.

The working principle of this switch is quite simple yet effective. When an input signal is applied to the device, the two or three output signals will be activated, depending on the desired configuration. The active input signal along with the associated output signal will then be latched until another input signal is applied. The latched input signal on the other hand will be disabled and the corresponding output signal will remain inactive.

The active low enable pin is used to activate the output latch and by disabling the output latch, it holds the previously decoded logic state until a new time-division multiplexed input is received. The output enable pins also allow individual control of outputs. This is essential in multiport busses that requires one output latch to be disabled while updating another.

The IDT72V71623BC8 is a high-speed, non-blocking simultaneous three-way multiplexer and decoder suitable for a variety of applications, such as switching and multiplexing data, clock and address signals in time-division multiplexed systems. Thanks to its high-speed capabilities and individual control pins, the IDT72V71623BC8 is an effective device for many digital systems.
