10 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.

10.1 Application Information

The SN74LV07A device is a low drive, open-drain CMOS device that can be used for a multitude of buffer type

functions. The inputs are 5.5-V tolerant. The outputs are open drain and 5.5-V tolerant; thus, allowing the device

to translate up to 5.5 V or down to any other voltage between GND and 5.5 V.

10.2 Typical Application

10.2.1 Design Requirements

This device uses CMOS technology and is open drain, so it has low output drive only. Care should be taken to

avoid bus contention, because it can drive currents that would exceed maximum limits. Parallel output drive can

create fast edges into light loads, so routing and load conditions should be considered to prevent ringing.

10.2.2 Detailed Design Procedure

1. Recommended Input Conditions:

–

For rise time and fall time specifications, see

Δt/ΔV in the Recommended Operating Conditions table.

–

–

2. Recommended Output Conditions:

–

Load currents should not exceed 35 mA per output and 50 mA total for the part.
