Product Overview: SN74LV139ADBR from Texas Instruments

The SN74LV139ADBR is a high-performance, dual 2-line to 4-line decoder/demultiplexer designed by Texas Instruments. This integrated circuit (IC) is part of the LV family, which indicates its low-voltage operation. It is specifically tailored for applications that require efficient and reliable decoding or demultiplexing functions, such as in address decoding for memory modules, control signal generation, and data routing applications.

Key Features

• Voltage Range: The device operates on a 2-V to 5.5-V V_CC supply voltage, making it suitable for interfacing with both 3.3V and 5V logic levels.
• Speed: The SN74LV139ADBR boasts a typical propagation delay time of 4.5 ns at 5V, providing swift performance for high-speed applications.
• Power Consumption: With a low power consumption and a typical ICC of only 20 µA, it is an excellent choice for power-sensitive designs.
• Logic Configuration: The device contains two independent 2-line to 4-line decoders, each with an enable input (nG) and two input lines (nA and nB) that are decoded into one of four outputs (nY0 to nY3).
• Output Capability: It can drive up to 8 LSTTL loads, providing ample current for downstream digital logic circuits.
• Packaging: The SN74LV139ADBR comes in a SSOP (Shrink Small-Outline Package) type DB with a body size of 5.30 mm x 5.30 mm.

Applications

This versatile decoder/demultiplexer is ideal for a wide range of applications, including:

• Memory decoding in computer systems
• Data multiplexing
