Universal Bus Functions

This Product Selection Guide contains information to help select products in the Universal Bus Functions category on DigiKey.com

Products in the universal bus function family are component-level products used for handling or operating on a series of (usually 8 or more) parallel logic signals known as a bus. Functions performed include temporary storage of data to be transmitted or received, buffering to allow a device such as a microprocessor having a limited output current capacity to transmit data over long interconnects at high speed, rotation or shifting of bit order within the bus, and others.


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

Number of Circuits: Indicates the number of circuits of similar functions that are implemented within the device.

Current - Output High, Low: The maximum recommended current flow through a device’s output pin. Multiple values reflect ratings that differ depending on the direction of the current flow.

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.
