Quad 2-input NAND Schmitt trigger

BU4093B / BU4093BF / BU4093BFV

The BU4093B, BU4093BF, and BU4093BFV are 4-circuit, 2-input NAND gates whose input pins all have a Schmitt

trigger function.

As the circuit threshold voltages are different when the input waveform rises and when it falls (V

IH

, V

IL

), they can be

used for line receivers, waveform rectification, multivibrators, and other purposes in addition to the customary usage

as a NAND gate. They may be used in place of the BU4011B which uses the same pin connection.

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.
