Shift Registers

This Product Selection Guide contains information to help select products in the Shift Registers category on

Shift registers are low-level logic devices commonly used to convert data in the form of digital logic signals between serial and parallel formats or to move the position of the data bits within a digital word. Typically implemented using an array of flip-flops integrated into one device, shift registers are a common component of more highly integrated logic devices, though they remain available for applications such as I/O expansion where the function in a discrete form may prove useful.


Logic Type: Describes the logic functions used within the circuit.

Output Type: Indicates the type of electrical signal the device provides, such as complimentary, open drain, or tri-state.

Number of Elements: Indicates the number of instances of a basic function that are incorporated within a device package.

Number of Bits per Element: Indicates the data width or the number of signals processed in parallel by each independent instance of a function contained within a device.

Function: Describes the main function or usage of the circuit.

Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.

Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.

Mounting Type: Indicates how the device is attached.

Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the suppliers device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.

Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
