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 (VIH, VIL), 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 dissipation. 1) Low power
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.
