(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The input negative-voltage and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
(3) The value of V_CC is provided in the recommended operating conditions table.
(4) The package thermal impedance is calculated in accordance with JESD 51-7.


Description

This single 2-line to 1-line data selector/multiplexer is designed for 1.65-V to 5.5-V V_CC operation.

The SN74LVC2G157 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.

NanoStar™ and NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the die as the package.

This device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
