SN74LS137DR - Texas Instruments 3-Line to 8-Line Decoders/Demultiplexers

The SN74LS137DR is a high-performance integrated circuit manufactured by Texas Instruments, renowned for its reliability and versatility in digital systems. This particular chip belongs to the 74LS family of logic devices, which are known for their low-power Schottky technology, offering a perfect balance between speed and power consumption. The SN74LS137DR is specifically designed as a 3-line to 8-line decoder or demultiplexer, making it an essential component for a wide range of applications including memory selection, data routing, and control logic implementations.

Key Features

• Logic Type: Decoder/Demultiplexer
• Number of Circuits: 1
• Number of Input Lines: 3
• Number of Output Lines: 8
• Output Current: -0.4mA, 8mA
• Supply Voltage: 4.75V to 5.25V
