The AUP family is TI's premier solution to the industry's low-power needs in battery-powered portable applications. This family ensures a very low static and dynamic power consumption across the entire VCC range of 0.8 V to 3.6 V, resulting in an increased battery life. This product also maintains excellent signal integrity (see Figure 1 and Figure 2).

† Single, dual, and triple gates

• Available in the Texas Instruments NanoStar™ Package
• Low Static-Power Consumption (ICC = 0.9 m A Max)
• Low Dynamic-Power Consumption (Cpd = 4 pF Typ at 3.3 V)
• Low Input Capacitance (CI = 1.5 pF Typ)
• Low Noise - Overshoot and Undershoot <10% of VCC
• Input-Disable Feature Allows Floating Input Conditions
• Ioff Supports Partial-Power-Down Mode Operation
• Input Hysteresis Allows Slow Input Transition and Better Switching Noise Immunity at Input

The exposed center pad, if used, must be connected only as a secondary GND or left electrically open.

SN74AUP2G125DCUR Pinout

Package: 8-VSSOP (DCU)

Pin Number	Pin Name	Type	Description
1	1OE	I	Output Enable for Buffer 1 (active low)
2	1A	I	Input A for Buffer 1
3	2Y	O	Output Y for Buffer 2
4	GND	P	Ground
5	2A	I	Input A for Buffer 2
6	1Y	O	Output Y for Buffer 1
7	2OE	I	Output Enable for Buffer 2 (active low)

Notes

• Dual Buffer Configuration: This device contains two independent bus buffers, each with an input (1A/2A), output (1Y/2Y), and output-enable control (1OE/2OE).
• 3-State Outputs: When OE is high, the corresponding output enters high-impedance state (Z).
• Input-Disable Feature: Allows floating input conditions without affecting operation.
• Exposed Center Pad: If present in the package, must be connected only as secondary GND or left electrically open.
• Operating Range: 0.8 V to 3.6 V VCC; optimized for 3.3 V operation.
