MC74HC238ADTR2G is a member of a high-performance family of logic gate switch circuits, multiplexers, and decoders. As part of this series, it features 3-state outputs which allow multiple sources to share the same output line without causing conflicts. The MC74HC238ADTR2G is a three-state, 8-bit buffer designed with two active LOW enable inputs, EIP and EIN. When the EIP input is LOW, the outputs will be 1s ( i.e., in the high impedance state) and when the EIN input is LOW, the outputs will be 0s. These outputs may be used to enable or disable other digital logic circuits.The MC74HC238ADTR2G utilizes TTL logic technology, making it ideal for use in driving a variety of different logic levels. Its large output drive capability makes it suitable for driving complex logic circuits, such as multiplexer channels, decoders, and address selectors. Furthermore, it incorporates the latest and most advanced semiconductor protection features to ensure a very high degree of protection against non-ideal operating conditions, such as over-temperature, over-voltage, and power supply transients.The main application field for the MC74HC238ADTR2G is switching, multiplexing and decoding logic signals. It can be used to enable or disable other digital logic circuits, such as multiplexer channels, decoders and address selectors. Its large drive capability also makes it suitable for driving complex logic circuits, such as address selectors, encoders and parity generators. The MC74HC238ADTR2G is also suited for use in data transmission, digital control systems and programmable logic devices.The working principle of the MC74HC238ADTR2G switch is based on its active-Low enable inputs. When either of the enable inputs are LOW, the outputs of the switch are 1s; when all the enable inputs are HIGH the device is disabled and the outputs become 3-state, assuming a high impedance state. The line bias input is also important, as it allows for the capability to drive both TTL and CMOS logic, depending on the situation.The MC74HC238ADTR2G is a versatile device that can be used in wide variety of applications. Its main application field is switching, multiplexing and decoding logic signals, but its large output drive capability also makes it suitable for use in complex logic circuits and digital control systems. Furthermore, the active-Low enables make it easy to control the output drive state and its line bias input allows for greater compatibility with various logic technologies.
