The IW4502B consists of six inverter/buffers with 3-state outputs. A logic "1" on the OUTPUT ENABLE input produces a high impedance state in all six outputs. This feature permits common busing of the outputs, thus simplifying system design. A logic "1" on th...
The IW4093B consists of four Schmitt-trigger circuits. Each circuit functions as a two-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 pos...
