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.
