Description
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. BU4011B series ICs are 2-input positive logic NAND gates.

Features
1) Low power consumption
2) Broad operating supply voltage range: 3V to 16V
3) High input impedance
4) High fan out
5) L-TTL2 and LS-TTL1 inputs can be directly driven
6) All outputs are equipped with buffers (except for BU4069UB)

Applications
   These products are suitable for applications requiring
      low power consumption and a high degree of noise tolerance
   The BU4030B/BU4070B series can be used in digital comparators
      and parity circuits
   The BU4093B series are suitable as line receivers,
      waveform shaping and multi-vibrators, etc.
   The BU4584B series can be used in waveform shaping circuits
      for inputs with a slow rise time and fall time
