The SN74LV157ADGVR is a quad 2-line to 1-line data selector/multiplexer, which is used in a digital system for data routing. Its medium-speed wide-operating-voltage range logic makes it a reliable device for data routing needs and it can be found in various applications including military, industrial, consumer, and communication technology. It is also an economical device in terms of cost.

The SN74LV157ADGVR switch is classified as a Logic - Signal Switches, Multiplexers, and Decoders. As the name suggests, it allows multiple signals to be combined into one and can also be used to enable multiple inputs to be routed to a single output. The device has an enable (enable/disable switch) and four address inputs (A0 to A3) which allow it to select one of the four data inputs (D0 to D3). The device can be used in a variety of configurations depending on how the enable and address inputs are used.

The SN74LV157ADGVR is a logic device that works in two basic operating modes. In the first, the device is enabled, and the corresponding data input is routed to the output based on the address inputs. In the second, the device is disabled, and the output is placed in a high-impedance state so that no data is transferred from any of the data inputs.

The SN74LV157ADGVR is capable of handling digital logic data at T25 and T60 commercial temperature ranges. The device is available in a 16-pin DIP package and is characterized for operation over a 0°C to 70°C temperature range. The inputs of the SN74LV157ADGVR are tolerant to 2V ESD levels and operate at both 3.3V and 5V power supplies. It has a maximum propagation delay of 105ns at 1MHz clock frequency and a maximum feedback delay of 215ns at the same frequency.

The SN74LV157ADGVR has a low level output drive capability of 1.4mA and a high level output drive of 10mA. It has a maximum capacitive load of 35pF and is able to provide glitch-free performance for up to 40ns. Its very low input current (1μA) also allows it to be used in ultra-low power applications.

In summary, the SN74LV157ADGVR is a quad 2-line to 1-line data selector/multiplexer which is used in digital systems for data routing. It is a Logic - Signal Switches, Multiplexers, and Decoders device and is capable of operating over a wide variety of commercial temperature ranges and power supplies. Its low input currents and low output drive capabilities allow it to be used in ultra-low power applications while its maximum propagation and feedback delays make it a reliable and cost effective data routing device.
