Product Overview: M74HC253RM13TR by STMicroelectronics

STMicroelectronics' M74HC253RM13TR is a high-speed CMOS Dual 4-Channel Multiplexer with 3-state outputs, designed to meet the demanding requirements of integration and power efficiency for modern electronic equipment. This device is part of the HC family, which is known for its high noise immunity and low power consumption, making it compatible with LSTTL outputs.

The M74HC253RM13TR features two 4-channel multiplexers, each with its own 2-bit binary control inputs, A and B, and an enable input, E. The multiplexer selects one of the four binary inputs based on the A and B inputs and routes it to the output, provided the enable input is set to a low logic level. When the enable input is high, the outputs go to a high impedance state, which is neither high nor low, effectively disconnecting the output from the circuit. This 3-state output feature allows for multiple devices to share the same output lines without interference, which is particularly useful in bus-oriented applications.

The device is housed in a compact and efficient TSSOP package, making it suitable for space-constrained applications. The M74HC253RM13TR operates over a wide voltage range from 2V to 6V, providing a flexible power supply option that is compatible with most standard logic levels. This ensures that the device can be easily integrated into a variety of digital systems without the need for additional level shifting components.

Overall, the M74HC253RM13TR is a versatile and reliable component that offers the high performance and low power consumption required for modern digital applications. Its robust design and advanced features make it an excellent choice for use in communication systems, data processing, instrumentation, and any other system that requires a high-quality multiplexing solution.
