9 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

9.1 Application Information

The SN74CBT3244 device can be used to control up to 4 bits with 2 channels simultaneously. The application

shown in Figure 4 is a 8-bit bus being controlled. The OE pins are used to control the chip from the bus

controller. This is a generic example and can apply to many situations. If an application requires fewer than 8

bits, ensure that the A side is tied either high or low on unused channels.

9.2 Typical Application

9.2.1 Design Requirements

as close as possible to the SN74CBT3244 device.

9.2.2 Detailed Design Procedure

1. Recommended input conditions:

–

–

2. Recommended output conditions:

–

Load currents must not exceed ±64 mA per channel

3. Frequency selection criterion:

–

Added trace resistance or capacitance can reduce maximum frequency capability; use layout practices as

directed in Layout Guidelines
