8 Application and Implementation

Note

and TI does not warrant its accuracy or completeness. TI’s customers are responsible for

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

8.1 Application Information

The SNx4ACT04 is a low-drive CMOS device that can be used for a multitude of bus interface type applications

where output ringing is a concern. The low drive and slow edge rates will minimize overshoot and undershoot on

the outputs.

8.2.1 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. Outputs can be combined to

produce higher drive but the high drive will also create faster edges into light loads, so routing and load

conditions should be considered to prevent ringing.

8.2.2 Detailed Design Procedure

1. Recommended Input Conditions

• Rise time and fall time specs: See (Δt/ΔV) in the Section 5.3.

• Specified high and low levels: See (VIH and VIL) in the Section 5.3.

2. Recommend Output Conditions

• Load currents should not exceed 25 mA per output and 75 mA total for the part.

• Outputs should not be pulled above VCC.
