SN74LVC1G139DCTR

Overview

The SN74LVC1G139DCTR is a single 2-to-4 line decoder manufactured by Texas Instruments. It operates within a supply voltage range of 1.65V to 5.5V and supports output currents of 32mA for both high and low states. The device is housed in an 8-pin VSSOP package with dimensions of 2.00mm x 2.30mm and a height of 0.90mm. It functions across a temperature range of -40°C to +85°C and is supplied in tape and reel packaging.

Feature Summary

• Provides decoding functionality from two address inputs to four distinct outputs
• Supports operation across a wide voltage spectrum from 1.65V to 5.5V
• Delivers strong drive capability with 32mA output current capacity

Applications

• Address decoding in embedded systems
