Product Overview: 74LV138N from NXP

The 74LV138N is a high-performance, low-voltage 3-to-8 line decoder/demultiplexer manufactured by NXP Semiconductors. This integrated circuit (IC) is designed to be used in applications that require the conversion of a binary input signal into a selection of one out of eight output lines, making it ideal for a wide range of decoding tasks in digital systems.

Key Features

• Low Voltage Operation: The 74LV138N operates at a voltage range of 2.0 to 5.5 volts, catering to low-power applications and compatibility with TTL levels.
• High-Speed Performance: With its ability to switch at high speeds, this IC is suitable for high-frequency operations, offering a typical propagation delay time of only 16 ns.
• Multiple Decoding Modes: It features three binary select inputs (A, B, C), an enable input, and eight mutually exclusive outputs, providing versatile decoding capabilities.
• Active Low Outputs: The outputs of the 74LV138N are active low, which means that the selected output line is pulled low when addressed by the input signals.
• Power Dissipation: It has a low-power dissipation, with a maximum ICC of 8 µA when disabled and 80 µA when enabled.
