BU4584

Standard ICs 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. Features 1) Low power dissipation. 2) Wide range of operating power supply voltage. 3) High input impedance. 4) High fan-out. 5) Direct drive of 2 L-TTL inputs and LS-TTL input.
