In the electronics industry, multiplexers, decoders and signal switches are key components for use in digital systems. These devices allow for efficient and reliable manipulation of signals and their corresponding data. The SN74ALS138ADRG4 is a 3-to 8-line decoder/demultiplexer that utilizes proprietary, advanced low power Schottky (ALS) series CMOS technology. The device combines low power consumption with fundamental characteristics such as high speed, high output drives, low quiescent supply current, high zone noise immunity, and low cost.

Overview

The SN74ALS138ADRG4 is a 3-to-8 line decoder/demultiplexer with two four-line inputs (A0–A3, B0–B3). Only the active low outputs (Y0–Y7) on the device are active during a single-access cycle. When either the A or B inputs are selected, the outputs become active one and only one output. This device also contains an active-low enable (G2A/G2B) input to permit either direct or gated selection of inputs.

Working Principle

As the SN74ALS138ADRG4 is a 3-to-8 line decoder/demultiplexer, it requires three select signals (A0-A2, B0-B2) and two enable inputs (G2A, G2B) to decode the information applied in the input to the specific output. In the device, if one enable signal (G2A / G2B) is active (at logic LOW level), the information applied in the inputs is combined in the combinatorial logic and applied to the outputs. The information in the input is decoded into 3-8 positions, depending on the inputs A0-A2 (B0-B2). If both enable inputs are active at the same time, then there will be no signal output at any of the outputs associated with the enable signal which is Low. In this way, the SN74ALS 138ADRG4 is capable of decoding/demultiplexing 3-to 8-line information.

Applications

The SN74ALS138ADRG4 is well-suited for high speed and low power system applications such as digital telecommunication systems, digital signal processor based devices, clock distribution networks, microprocessor systems, and logic systems. Therefore, this device can be found in a wide range of digital data processing, machine control, and communication systems.

The SN74ALS138ADRG4 decoder/demultiplexer device is flexible, robust, and has a number of advantageous features. The device is designed to provide high performance with very low power consumption, high output drive capability and excellent noise immunity. The device is also highly reliable due to its proprietary, advanced low power Schottky (ALS) series CMOS technology. As such, the SN74ALS138ADRG4 is an ideal choice for mixed-signal, low-power applications.
