The 74HC32 is a 14 Pin Quad 2-Input OR Gate IC.?The 74HC32 provides four independent 2-input OR gates?with standard push-pull outputs. The device is designed for operation?with a power supply range of 2.0V to 6.0V.

74HC4040 is a 16 Pin 12-Stage Binary Ripple Counter IC?having 2V to 6V Operating Voltage range with 1uA low input current. It has a clock input (CP),?an overriding asynchronous master reset input (MR) and twelve parallel outputs (Q0 to?Q11). The counter advances on the HIGH-to-LOW transition of CP.
