DESCRIPTION/ORDERING INFORMATION

This analog switch is operational at 0.8-V to 2.7-V V
operation.

The SN74AUC2G53 can handle both analog and digital signals. The device permits signals with amplitudes of up
to V

(peak) to be transmitted in either direction.

CC

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

Applications include signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for
analog-to-digital and digital-to-analog conversion systems.

, but is designed specifically for 1.1-V to 2.7-V V

(2) DCT: The actual top-side marking has three additional characters that designate the year, month, and assembly/test site.

DCU: The actual top-side marking has one additional character that designates the assembly/test site.
YEP/YZP: The actual top-side marking has three preceding characters to denote year, month, and sequence code, and one following
character to designate the assembly/test site. Pin 1 identifier indicates solder-bump composition (1 = SnPb, ⋅ = Pb-free).

(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) All voltages are with respect to ground unless otherwise specified.
(3) The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
