BU4001B series ICs are 2-input positive logic NOR gates, each with four built-in circuits. A buffer achieved by an inverter added at the gate output improves the input/ output propagation characteristics and minimizes variation in the propagation time caused by an increase in the load capacitance. BU4011Bseries ICs are 2-input positive logic NAND gates. Four circuits are contained on a single chip. An inverter-based buffer is included at the gate output, enabling improved input / output propagation characteristics, and an increased load capacitance minimizes fluctuations in the propagation time.
BU4030B and BU4070B series ICs are exclusive OR gates, each with four built-in circuits. An inverter-based buffer was incorporated at the gate output for enhanced I/O voltage characteristics, and the load capacitance has been increased in order to minimize fluctuations in the propagation time. BU4081B series are 2-input positive logic AND gates with four circuits
mounted on a single chip. An inverter-type buffer was added to the gate output, improving input/output transmission speed, and an increased load capacitance suppresses fluctuations in the transmission time. BU4093B series ICs are 4-circuit, 2-input NAND gates whose input pins all have a Schmitt trigger function. BU4069UB series ICs are 6-circuit inverters with no buffers. A single-stage gate configuration reduces propagation time. BU4584B series ICs are inverter-type Schmitt trigger circuits, each incorporating 6 circuits in a single chip.
