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 specially designed 3-V LVTH family uses the 0.8-µ BiCMOS process technology for bus-interface functions.

Like its 5-V ABT counterpart, LVHT provides up to 64 mA of drive, low propagation delays. The bus-hold feature

eliminates requirements for external pullup resistors and I/Os that can handle up to 7 V, which allows them to act

as 5-V/3-V translators.

9.2.1 Design Requirements

The SN54LVTH16373 utilizes BiCMOS technology with high-drive currents. Care must be taken to avoid bus

contention that can disrupt system functionality and/or cause violation of absolute maximum ratings.
