CD40106 - Hex Schmitt Trigger Inverter IC The CD40106 IC consists of six Schmitt-Trigger inputs. Each circuit functions as an inverter with Schmitt-Trigger input. The trigger switches at different points for positive- and negative-going signals. The difference between the positive-going voltage (VP) and the negative-going voltage (VN) is defined as hysteresis voltage (VH). A Schmitt trigger input means that the threshold voltage for going from a HIGH to a LOW input is different from the threshold for going from LOW to HIGH. CD40106 Pinout Configuration: Pin Number Pin Name Description 1,3,5,11,13,15 Schmitt Input Pins Input pins of the Schmitt trigger 2,4,6,10,12,14 Schmitt Inverted Output Pins Output pins of the Schmitt trigger 7 Ground Connected to the ground of the system 14 Vcc (+5V) Resets all outputs as low.

CD4011 - Quad 2-Input NAND Gate IC The CD4011 is a quad package 2-Input NAND gate IC (Integrated Circuits). That is, it has four NAND gates inside a single package and each gate has two input lines and one output line. All the inputs and outputs are buffered and this improves transfer characteristics by providing a very high gain. The CD4011 IC operates at 5V, 10V, 15V, and even 20V. When operating at 5V the maximum low-level input voltage is 0.5 and the minimum high-level input voltage is 4.5. All four gates share the same power rail but can operate independently.
