SN74LV157ADBR - Texas Instruments
The SN74LV157ADBR from Texas Instruments is a high-performance, quadruple 2-line to 1-line data selector/multiplexer that operates from a voltage range of 2 V to 5.5 V. This device is designed to provide the flexibility to select one of two data sources for each output. It is particularly suitable for implementing noninverting multiplexers with different binary control inputs, A and B, and an enable input (G).
Encased in a SSOP (Shrink Small Outline Package) with a DBR suffix, this integrated circuit ensures a compact footprint on printed circuit boards, making it ideal for space-constrained applications. The SN74LV157ADBR is characterized for operation from -40°C to 85°C, making it reliable for use in a wide range of commercial and industrial environments.
Key Features:
- Voltage Range: Operates from a 2 V to 5.5 V VCC supply, providing compatibility with TTL logic levels.
- High Speed: Propagation delay time is typically 4.5 ns at 5 V, facilitating rapid data processing and switching.
- Low Power Consumption: Features a typical power consumption of only 20 µA (max) at 5.5 V, making it suitable for battery-operated and power-sensitive applications.
- Output Drive Capability: Capable of driving up to 3.6 mA at 5 V, allowing for direct drive of a wide range of loads.
- Multiple Configurations: Can be used as four 2-line to 1-line multiplexers, two 4-line to 1-line multiplexers, or one 8-line to 1-line multiplexer, offering design flexibility.
- Latch-Up Performance: Exceeds 250 mA per JESD 17, ensuring stable operation under transient conditions.
- ESD Protection: Provides human-body model (HBM) electrostatic discharge protection exceeding JESD 22, ensuring robustness for handling and assembly.
The SN74LV157ADBR is part of Texas Instruments' SN74LV family, known for its low-voltage operation and low-power consumption, making it an excellent choice for interfacing with high-speed and memory-driven applications in telecommunications, computing, and industrial electronics.
