SN74LVC2G157DCTR

The Texas Instruments SN74LVC2G157DCTR is a single 2-line to 1-line data selector multiplexer designed for 1.65-V to 5.5-V VCC operation. This device features a common strobe (G) input. When the strobe is high, Y is low and Y is high. When the strobe is low, a single bit is selected from one of two sources and is routed to the outputs. The device provides true and complementary data.

Key electrical characteristics include a maximum propagation delay of 6 ns at 3.3 V, low power consumption of 10 µA, and a maximum supply current of 24 mA. The output drive is 24 mA at 3.3 V. Latch-up performance exceeds 100 mA per JESD 78, Class II, and ESD protection exceeds 2000 V for the Human Body Model (A114-A) and 1000 V for the Charged-Device Model (C101).

This multiplexer is available in the Texas Instruments NanoFree™ package and supports 5-V VCC operation with inputs accepting voltages up to 5.5 V. It is fully specified for partial-power-down applications using Ioff, which disables outputs to prevent damaging current backflow. The device is suitable for surface mount applications and comes in an 8-LSSOP, 8-MSOP package.

It is designed for use in applications requiring signal selection and routing. The device's ability to translate inputs from a maximum of 5.5 V down to the VCC level makes it versatile for various voltage translation needs.
