DESCRIPTION/ORDERING INFORMATION
This dual bus buffer gate is designed for 1.65-V to 5.5-V VCC operation.
NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the die as the
package.
The SN74LVC2G126 is a dual bus driver/line driver with 3-state outputs. The outputs are disabled when the
associated output-enable (OE) input is low.
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a
pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the
driver.

(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.
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).
