Quad exclusive OR gate
BU4030B / BU4030BF
BU4070B / BU4070BF
The BU4030B / F and BU4070B / F are exclusive OR gates.
Four circuits are contained on a single chip. An inverter-based buffer is added to the gate output for an enhanced I / O
voltage characteristic, and the load capacitance has been increased to minimize fluctuation in the propagation time.
In addition, these products feature low power consumption and a high noise margin.
These can also be used in digital comparators and parity circuit applications.
