HEF4093B
HEF4093B is Quad 2-input NAND Schmitt trigger manufactured by NXP Semiconductors.
description
The HEF4093B is a quad two-input NAND gate. Each input has a Schmitt trigger circuit. The gate switches at different points for positive-going and negative-going signals. The difference between the positive voltage (VT+) and the negative voltage (VT- ) is defined as hysteresis voltage (VH).
It operates over a remended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.
