Parity Generators and Checkers

This Product Selection Guide contains information to help select products in the Parity Generators and Checkers category on

Devices in the parity generator and checker logic family are component-level devices used to evaluate the number of bits in a digital word that are set to 1, and generate (or evaluate) an additional parity bit which indicates whether the number of bits in the word set to 1 is even or odd. This function is commonly used as a simple means of detecting data errors that may have been introduced during transmission.


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

Number of Circuits: Indicates the number of circuits of similar function 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 direction of 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.
