Priority Logic Gate Array

Product Specifications

Technical details and manufacturing context for Priority Logic Gate Array

Definition

The Priority Logic Gate Array is the core processing unit of a priority encoder, a component used in digital systems to manage multiple input signals. Its primary function is to evaluate all input lines simultaneously and identify which one has the highest priority when several are active. The array implements the logic that translates this priority into a binary code, which is then output for further processing. Additionally, it often generates a valid output indicator to signal that at least one input is active. The circuit is constructed from interconnected logic gates, typically AND, OR, and NOT gates, arranged according to a priority encoding truth table. When multiple inputs are active, the internal connections ensure that only the highest-priority input is encoded, with lower-priority inputs being ignored. Priority is usually determined by physical position, with lower-numbered inputs having higher priority. The array is fabricated on a silicon semiconductor substrate and is available in a surface-mount SOIC-16 package. Key electrical parameters include a supply voltage range of 3.3–5.0 V, operating temperature from -40 to 85 °C, propagation delay of 2.5–5.0 ns, input current of ±1 µA, output drive capability of ±24 mA, logic level threshold of 0.3–0.7 V, input capacitance of 3–5 pF, power consumption of 10–50 mW, ESD protection of ±2000 V (human body model), operating humidity of 5–95% RH, and weight of 0.5–1.0 g. These values are reference ranges and must be verified for the specific model and application. Standards such as IEC 60134, IEC 60068-2-1/2, JEDEC MS-012, IEC 61000-4-2, and IEC 60068-2-78 are listed as verification references. Always confirm model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The Priority Logic Gate Array consists of interconnected logic gates (typically AND, OR, and NOT gates) arranged to implement a priority encoding truth table. When multiple input signals are received, the circuit's internal connections ensure that only the highest-priority input (usually determined by physical position, with lower-numbered inputs having higher priority) is encoded into the output binary code, while lower-priority active inputs are ignored. The output includes the binary code and a valid indicator.
