SN74LV138ATRGYRG4: A High-Performance Decoder/Demultiplexer from Texas Instruments

The SN74LV138ATRGYRG4 is a high-performance, low-voltage 3-to-8 line decoder/demultiplexer designed by Texas Instruments to provide efficient solutions for a wide range of digital applications. This integrated circuit is part of the SN74LV family, which is renowned for its low-voltage operation and outstanding performance.

This particular device is capable of decoding three binary-coded inputs into one of eight mutually exclusive outputs when both the enable inputs, E1 and E2, are low. The third enable input, E3, is high. The SN74LV138ATRGYRG4 is designed for use in high-performance memory-decoding or data-routing applications requiring very short propagation delay times. In systems where hardware decoding is necessary, this IC is an ideal choice due to its high speed and low power consumption.

The device features a typical t<sub>pd (propagation delay time) of 4.5 ns with a low power consumption of 20 µA max I<sub>CC. Its operating voltage ranges from 2 V to 5.5 V, making it compatible with a variety of logic families and allowing it to be used in mixed-voltage systems. Additionally, the SN74LV138ATRGYRG4 supports up to 5.5 V V<sub>CC operation and has ±24-mA output drive at 3.3 V. This makes it suitable for driving heavier loads or for interfacing with other logic levels in a system.

The device comes in a compact 16-pin VQFN (RGY) package, which is optimized for space-constrained applications. It also features a wide operating temperature range of -40°C to 85°C, ensuring reliability and performance in various environmental conditions.

With its low-power Schottky circuitry, the SN74LV138ATRGYRG4 reduces power consumption without sacrificing speed. It is fully characterized for both 5-V and 3.3-V operation, further ensuring its versatility in different system designs. For designers looking for a reliable and efficient decoder/demultiplexer, the SN74LV138ATRGYRG4 from Texas Instruments is an excellent choice that combines performance with power efficiency.
