Standard ICs 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. Features • 1) Low power dissipation. 2) Wide range of operating power supply voltages. 3) High input impedance. 4) High fan-out. 5) Direct drive of 2 L-TTL inputs and 1 LS-TTL input. •Absolute maximum ratings (V Parameter Power supply voltage Power dissipation O [ ... ]
