Product Overview: 74LV138DB - NXP Semiconductors

The 74LV138DB from NXP Semiconductors is a high-performance, low-voltage 3-to-8 line decoder/demultiplexer with five inputs, including three binary weighted address inputs (A0, A1, and A2), a chip enable input (E1), and a chip disable input (E2). This integrated circuit is part of the 74LV family, which is characterized by its low-voltage operation and compatibility with TTL levels.

Designed for use in high-performance memory-decoding or data-routing applications, the 74LV138DB requires the use of the binary address inputs and the enable/disable inputs to select one of the eight output lines. The outputs are inverted versions of the selection, ensuring that when the device is enabled, one output will be low (active) while the others remain high (inactive).

The 74LV138DB offers a wide operating voltage range from 1.2V to 5.5V, which allows for use in various logic systems and ensures compatibility with low-voltage applications. The low power consumption of this device makes it an excellent choice for battery-operated devices, while its high noise immunity ensures stable performance in electrically noisy environments.

The functional and pinout compatibility with the 74 series logic family allows for easy integration into existing designs and the opportunity for a seamless upgrade path. The 74LV138DB is available in a DB package, which is a small outline integrated circuit (SOIC) package, making it suitable for space-constrained applications.

Key features of the 74LV138DB include:

• 3-to-8 line decoder/demultiplexer with inverting outputs
• Wide operating voltage range: 1.2V to 5.5V
• Low power consumption
• High noise immunity
• Functional and pinout compatibility with the 74 series
• Available in SOIC package for space-saving applications

In summary, the 74LV138DB from NXP Semiconductors is an essential component for designers seeking a reliable and efficient solution for decoding and demultiplexing applications within a broad range of operating voltages and with a focus on low-power consumption.
