9 Application and Implementation

9.1 Application Information

The SN74HC595-Q1 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.

9.2 Typical Application

Figure 11. Typical Application Schematic

9.2.1 Design Requirements

This device uses CMOS technology and has balanced output drive. Take care to avoid bus contention because it

can drive currents that would exceed maximum limits. The high drive will also create fast edges into light loads

so routing and load conditions should be considered to prevent ringing.
