74LVC1G97DW-7 Application Field and Working Principle

The 74LVC1G97DW-7 is an integrated logic function that can be categorized as Logic - Gates and Inverters - Multi-Function, Configurable. It is a logic device with two configurable functions, capable of adding two input signals or one inverting signal. It features 1.65V to 3.6V supply voltage, low static power consumption, and wide operating temperature range.

Applications

The 74LVC1G97DW-7 is appropriate for low-voltage applications, and can be used in any circuit that requires two configurable logic gates or an inverting signal. The ability to configure the device to work as either a two-input adder or an inverting signal make it particularly suitable for applications where flexibility is essential. This device can be used in:

• Medical Instrumentation
• Consumer Devices
• Industrial Control
• Home Automation
• Automotive Electronics

Working Principle

The 74LVC1G97DW-7 is a dual configurable CMOS logic device. The device features two configurable circuits that can be set to perform either two-input adder (Y = A+B) or inverting signal (Y = A+B-1) operations. The two switches of the device each have two control inputs, allowing two functions to be selected per switch. Each of the configurable circuits also has two data inputs, A and B. By controlling the logic state of the two switches, it is possible to set the device to perform either a two-input adder or an inverting signal operation.

When the device is set to the adder mode, the two binary digits, A and B, are added together while the third input of each switch (the control input) is set to a logic high state. With the third input set to a logic high, a logic high sum (Y) is outputted when both A and B are set to a logic high. When either A or B is set to a logic low, a logic low sum (Y) is outputted. This operation is also known as an OR gate.

When the device is set to the inverting signal mode, the binary digits A and B are added together while the third input of each switch (the control input) is set to a logic low state. With the third input set to a logic low, a logic low sum (Y) is outputted when both A and B are set to a logic low. When either A or B is set to a logic high, a logic high sum (Y) is outputted. This operation is also known as an XOR gate.

The 74LVC1G97DW-7 is an ideal device for applications that require a logic function with two configurable circuits and a wide operating temperature range. With its 1.65V to 3.6V supply voltage, low static power consumption, and wide temperature range, this device is capable of operating in a variety of environmental conditions.
