The DG412LDY-T1 is an integrated circuit (IC) multiplexer/demultiplexer device designed for specialized application fields and with a specific, useful working principle. A multiplexer or mux is a switch that chooses one of several input signals, and a demultiplexer or demux is a device that takes one input signal and distributes it to multiple output signals.
The DG412LDY-T1 is a versatile dual 4:1 multiplexer/demultiplexer device, perfect for applications where two independent 4-to-1 mux/demux functions are needed. The DG412LDY-T1 is composed of two DG411 4-to-1 multiplexers and one DG413 1-to-4 demultiplexer, all with their associated control logic included. They provide a compact dual 4-to-1 and 1-to-4 multiplexer/demultiplexer and are designed for use with TTL and CMOS logic and analog signals.
The DG412LDY-T1 offers wide fan-out capability, low on resistance and low off-state leakage. The DG412LDY-T1 is fabricated in a BiCMOS process, which allows it to support both TTL and CMOS logic and analog signals. It is available in a variety of packages such as SOIC, TSOP, QSOP, and PDIP. The device is fully specified over the temperature range of -55°C to +125°C.
The DG412LDY-T1 operates in either multiplexer or demultiplexer mode, depending on the control selection-MS1, and MS2 pins. In multiplexer mode, the device selects one data signal from four independent inputs and routes it to the output channel. The data channel selection is done by setting the logic of MS1, and MS2 pins. For example, if MS1, and MS2 are both set to logic 1, the signal at D0 will be selected as the output data signal. The signal is routed to the common output channel. In demultiplexer mode, the signal at the common E0 pin is distributed to the four outputs, selected by logic 1, and 0 settings at the MS1, and MS2 pins.
The DG412LDY-T1\'s versatile application fields and robust operational specs make it a great choice for a variety of demanding applications. Its low on-resistance and low off-state leakage make it ideal for signal routing and signal isolation in industrial, automotive, telecommunications and consumer electronics. The DG412LDY-T1 can be used as an address decoder in application such as video systems and computer address busses. It can also be used to control motor direction in robotic applications or to route control signals in electrical and power distribution systems.
