Hex Schmitt trigger
BU4584B / BU4584BF / BU4584BFV
The BU4584B, BU4584BF, and BU4584BFV are inverter-type Schmitt trigger circuits, with six circuits mounted on a
single chip. These are ideal when enhanced noise immunity is required, and when wave form rectification circuits
with slow rise or fall input times are involved.
