10 Application and Implementation

10.1 Application Information

The AUP family is TI's premier solution to the industry’s low-power needs in battery-powered portable

of 0.8 V to 3.6 V, resulting in an increased battery life. This product also maintains excellent signal integrity. It

has a small amount of hysteresis built in allowing for slower or noisy input signals. The lowered drive produces

slower edges and prevents overshoot and undershoot on the outputs.

10.2 Typical Application

Figure 5. Typical Application Schematic

10.2.1 Design Requirements

This device uses CMOS technology and has balanced output drive. Care should be taken to avoid bus

contention because it can drive currents that would exceed maximum limits.

10.2.2 Detailed Design Procedure

1. Recommended Input conditions

–

Rise time and fall time specs. See (

Δt/ΔV) in Recommended Operating Conditions

–

–

2. Recommend output conditions

–

Load currents should not exceed 20 mA on the output and 50 mA total for the part
