Texas Instruments SN74LV8T138-EP 3-to-8 Line Decoder/Demultiplexer

Introduction

The Texas Instruments SN74LV8T138-EP is a versatile 3-to-8 line decoder/demultiplexer designed for efficient digital signal control and communication module interfacing. With its wide operating voltage range and advanced features, this component is ideal for various applications in modern electronics.

Part Description

The SN74LV8T138-EP features two active low output strobes (G1 and G0) and one standard output strobe (G2). When the outputs are gated by any of the strobe inputs, all outputs are forced into a high state. Conversely, when the outputs are not disabled, only the selected output is low while all others remain high. This device supports a voltage range from 1.65V to 5.5V, making it suitable for voltage translation between different CMOS levels. It is designed with a lower threshold circuit for up translation of lower voltage CMOS inputs and includes 5V tolerant input pins for down translation. The device is built to withstand a temperature range of -55°C to +105°C and features gold bond wires for enhanced reliability.
