The SN74LVC157ADT is a high-performance, quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments designed to operate from 2.7 V to 3.6 V. This makes it ideal for use in both 3.3 V and 2.5 V systems. The device can also interface with 5 V signals without any additional components, making it versatile for mixed-voltage applications.

Featuring a 16-pin SOIC (Small Outline Integrated Circuit) package, the SN74LVC157ADT offers four identical 2-line to 1-line data selectors/multiplexers with 3-state outputs. Each multiplexer has two select inputs (A and B), four data inputs (0 to 3), and one output (Y). The select inputs determine which data input is connected to the output.

With a typical voltage range of 2.7 V to 3.6 V, the SN74LVC157ADT has a low power consumption and supports a wide operating temperature range of -40°C to 85°C. The device features a high drive capability and is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

The SN74LVC157ADT also includes latch-up performance that exceeds 250 mA per JESD 17, and it is specified for ESD protection exceeding JESD 22. This ensures that the device is robust and suitable for various industrial applications where reliability is paramount.

In summary, the SN74LVC157ADT from Texas Instruments is a versatile and reliable data selector/multiplexer that is suitable for a wide range of applications. Its compatibility with multiple voltage levels, low power consumption, and robust protection features make it an excellent choice for designers looking to create flexible and durable systems.
