MC74HC32ADG

MC74HC32ADG is a Quad 2-Input OR Gate Integrated Circuit (IC) designed for use with TTL logic and also compatible with low power Schottky TTL (LSTTL). It has high speed outputs and high noise immunity inputs. It has been designed for applications in Commercial and Industrial grade products that operate at low power levels. The IC has a base package of one 16 pin DIP (Dual In-line Package) and is available in both AC and LS versions. The device comes in several different versions including CMOS, TTL and Hi-Speed versions.

Application Field

The MC74HC32ADG has a wide range of applications. It is commonly used in digital circuits, where it can be used to combine logic signals. Its four independent OR gates can be used to compare and combine up to four logic signals, whether they are input directly to the circuit, or to each of the four OR gates. Several common applications include combining inputs from multiple switches into a single signal, bidirectional signal conversion, low power Schottky TTL, digital signal conditioning and signal selection.

Working Principle/Function

The four individual two-input OR gates within the MC74HC32ADG are independent of each other. Each OR gate is capable of accepting two digital inputs that can be either high (1) or low (0). When either of the two inputs is high (1) the output of the OR gate is high (1). When both inputs are low (0) the output of the OR gate is low (0). If a high signal is present at both inputs the output will remain high (1). This set of logical functions can be used to combine three or more signals into one, as well as selecting which of two signals will be sent as the output.

The MC74HC32ADG also includes integrated logic-level inhibitors to prevent high-frequency oscillations and reduce output noise. The device is housed in a 16-pin, 1.5mm2 high-density ceramic package, and requires only 3.3V, 4.5V or 5.5V power supplies to operate.

Conclusion

The MC74HC32ADG is an ideal choice for applications requiring a low-power, reliable OR gate solution. Its four two-input OR gates can be used to combine, compare, select or condition digital signals quickly and accurately. Its integrated logic-level inhibitors improve noise immunity and prevent high-frequency oscillations. With its small package, low power consumption and broad power supply range, the MC74HC32ADG can be used in a wide variety of applications.
