The SN74HC42NS from Texas Instruments is a high-performance, 4-line to 10-line decoder/demultiplexer designed to address the need for converting binary input signals to one-of-ten output lines. This integrated circuit is part of the 74HC family, which is well-known for its high-speed CMOS technology.

This decoder/demultiplexer is specifically designed to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. With its wide operating voltage range of 2V to 6V, the SN74HC42NS is versatile and can be used in various applications that require low power consumption and a high noise margin.

Key Features:

• Logic Family: 74HC
• Logic Type: 4-Line to 10-Line Decoder/Demultiplexer
• Operating Voltage Range: 2V to 6V
• Output Current: High-level output current of -5.2 mA; Low-level output current of 5.2 mA
• Propagation Delay Time: Fast propagation delay time, which varies with operating voltage and temperature
• Temperature Operating Range: -40°C to 85°C, suitable for industrial environments
• Mounting Type: Surface Mount
• Package / Case: SOP-16 (Small Outline Package)

The SN74HC42NS is designed with an enable function that, when active, disables all outputs, providing the capability to place all output lines in a high-impedance state. This feature is particularly useful in bus-oriented systems where multiple outputs may need to be connected to a common bus without the risk of bus contention.

With its robust design and industry-standard packaging, the SN74HC42NS is ideal for use in a wide range of digital applications, including computers, data processing, telecommunications, and control systems. Texas Instruments' commitment to quality ensures that this decoder/demultiplexer meets the stringent requirements for reliable and consistent performance in your electronic circuits.
