This Product Selection Guide contains information to help select products in the Buffers, Drivers, Receivers, Transceivers category on DigiKey.com
Logic buffers, drivers, receivers, and transceivers allow isolated access to logic signals from one circuit for use in another circuit. Buffers pass their input signal, either unchanged or inverted, to their output and may be used to clean up a weak signal or drive a load. In a boolean logic simulator, a buffer is mainly used to increase propagation delay. Logic receivers and transceivers allow isolated communication between data buses.
SelectionCharacteristics
Logic Type: Indicates the operational mode(s) of a featured IC, which has categorical significance for performance traits such as electrical efficiency.
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.
Input Type: Describes a device’s input characteristics or how the device’s input will behave with a given signal.
Output Type: Indicates the type of electrical signal the device provides, such as CMOS, logic, or tri-state.
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.
