Product Overview: 74LV138D by NXP Semiconductors
The 74LV138D is a high-performance, low-voltage 3-to-8 line decoder/demultiplexer integrated circuit produced by NXP Semiconductors. This IC is designed to be compatible with standard 74 series logic while offering the benefits of low-voltage operation. It is particularly suitable for use in battery-operated systems, portable devices, and other applications where power efficiency is paramount.
Featuring a 3.3V supply voltage with 5V tolerant inputs, the 74LV138D ensures compatibility with older 5V systems while operating at a lower voltage to save power. The device has three binary select inputs (A, B, and C), an active LOW enable input (E1), and two active HIGH enable inputs (E2 and E3). When the enable inputs are appropriately configured, one of the eight mutually exclusive outputs (Y0 to Y7) will be selected based on the binary value of the inputs.
With its ability to sink or source 4 mA at 3.3V, the 74LV138D can drive LEDs or interface with other logic devices directly. Its hysteresis characteristics on all inputs allow the chip to be used in noisy environments, increasing its robustness and reliability. The device also features a wide operating temperature range, making it suitable for industrial applications.
The 74LV138D comes in a standard SO16 package, which is a small outline package that is both space-saving and convenient for automated assembly processes. Its low power consumption and high noise immunity are achieved through the use of CMOS technology, which also ensures low quiescent current.
This decoder/demultiplexer is ideal for applications such as address decoding for memory modules, control signal generation, and multiplexing signals from multiple sources to a single destination. Its high performance and low power consumption make the 74LV138D a versatile and efficient solution for a wide range of digital logic applications.
In summary, the NXP 74LV138D offers designers a reliable and power-efficient solution for decoding and demultiplexing applications, with the added benefit of being compatible with both 3.3V and 5V systems.
