74155 Dual 2-to-4 Line Decoder/Demux (74HC155/74LS155)

Description

74HC155 – 74155 (Dual 2-to-4-line Decoders/demultiplexers) is a high-quality electronic component designed for Arduino, prototyping, and educational electronics. This circuit features dual 1-line-to-4-line demultiplexer with individual strobes and common binary-address input. When both sections are enabled by the strobes, the common binary-address inputs sequentially select and route associated input data to the appropriate output of each section. The individual strobes permit activating or inhibiting each of the 4-bit sections as desired. Data applied to input 1C is inverted through its outputs. The inverter following the 1C data input permits use a 3-to-8-line decoder or 1-to-8line demultiplexer without external gating. Features Current – Output High, Low: 5.2mA, 5.2mA. Voltage Supply Source : Single Supply. Voltage – Supply: 2V ~ 6V. Package / Case: 16-DIP (0.300″, 7.62mm). 74HC155 datasheet It’s perfect for DIY makers, students, and anyone building custom electronic circuits or STEM kits.
