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 SNx4HC00 is a low-power, wide-operating-voltage NAND gate. This device can drive up to 10 LSTTL loads

9.2 Typical Application

Figure 3. Typical NAND Gate Application and Supply Voltage

9.2.1 Design Requirements

The SNx4HC00 devices use CMOS technology and have balanced output drive. Take care to avoid bus

contention because it drives currents that would exceed maximum limits. The high drive also creates fast edges

into light loads. Routing and load conditions must be considered to prevent ringing.

9.2.2 Detailed Design Procedure

•

Recommended input conditions:

–

•

Recommended output conditions:

–

Load currents must not exceed 25 mA per output and 50 mA total for the part.
