4073 IC Triple 3-Input AND Gate
The CD4073BE is a triple 3-input AND gate integrated circuit built using CMOS technology, providing high noise immunity and low static power consumption. Each of the three logic gates within the IC takes three inputs and delivers a logic HIGH output only when all three inputs are HIGH.
Engineers frequently use this logic IC in digital electronics projects that require strict logic gating, such as control systems, timing circuits, and logic-level monitoring. The CD4073BE functions reliably across a wide voltage range from 3V to 15V, making it compatible with both TTL and CMOS systems.
