SN74CB3Q3125PWRE4

SN74CB3Q3125PWRE4 is a logic signal multiplexer. It can be used to select one from the multiple lines of input and direct the data to one output line. The device is a 3-to-1 multiplexer, which means it can switch 3 separate input lines to one output line. The SN74CB3Q3125PWRE4 is manufactured by Texas Instruments and is part of their ‘CB’ family of logic devices. The device has a wide range of applications, but is most commonly used in communication systems and data buses.

Application Field

The SN74CB3Q3125PWRE4 can be utilized in virtually any field which requires multiplexing of signals. It is particularly useful in applications dealing with switching multiple inputs to one data bus. Typical applications which make use of the SN74CB3Q3125PWRE4 logic multiplexer include data communication networks, telecommunication systems, computer memory interfacing, medical instrumentation and automatic test equipment.

Working Principle

The SN74CB3Q3125PWRE4 multiplexer has a straightforward operation. The data to be multiplexed is connected to the ‘A’, ‘B’ and ‘C’ input lines of the device. The multiplexer selects one of these input lines and directs the data to the output line. The selection of the input line to be used is determined by the control signals applied to the ‘Sel’ input line of the multiplexer. Depending on the combination of the control signals, one input line of the multiplexer is selected and the data is directed to the output line. The output voltage of the multiplexer is derived directly from the selected input line, with a small delay due to the propagation delay of the signal.

The SN74CB3Q3125PWRE4 multiplexer is designed to operate in both TTL and CMOS logic environments. It can be used in wide temperature range, from -40°C to 105°C. It has low power consumption and is capable of switching at high speed, with propagation delay times as low as 6 ns. The device is supplied in a low profile, space saving 16-pin plastic SSOP package.

Conclusion

The SN74CB3Q3125PWRE4 logic multiplexer is an ideal device for applications dealing with switching multiple inputs to one data bus. It is designed to operate in both TTL and CMOS logic environments, is supplied in a low profile, space saving 16-pin plastic SSOP package and consumes very little power. The propagation delay of the device is very low and it can offer reliable operation in the extended temperature range from -40°C to 105°C.
