The JM54AC521BRA belongs to the 54AC series. It serves as an 8-bit identity comparator with an output register and three-state outputs. Key features:
1. 8-bit Identity Comparisons: The JM54AC521BRA IC performs parallel equality comparisons between two 8-bit binary words. It checks if the two inputs are identical, bit by bit, and provides output based on the comparison result.
2. Output Register: This IC includes an onboard output register, allowing the comparison result to be latched and held at the output pins. This feature ensures that the comparison result is only updated when desired and remains stable until further instructions are given.
3. Three-State Outputs: The output pins of the JM54AC521BRA IC are equipped with three-state functionality. This means that the outputs can be actively driven to logic high or low levels, or be placed in a high-impedance state (disconnected) to avoid conflicts in the circuit.
4. Edge-Triggered Operation: The IC operates on edge-triggered clocking inputs. It accepts two clock inputs, CLK1 and CLK2, which are synchronized internally to avoid any inconsistencies during comparisons. The comparison process is initiated when the clock transitions from low to high level (rising edge-triggered)
