CD4504BE

The CD4093B consists of four Schmitt-trigger circuits. Each circuit functions as a 2-input NAND gate with Schmitt trigger action on both inputs.
The gate switches at different points for positive and negative-going signals.
The difference between the positive (VT+) and the negative voltage (VT−) is defined as hysteresis voltage (VH).All outputs have equal source and sink currents and conform to standard B-series output drive (see Static Electrical Characteristics).
