1. general description the 74lvc4245a is an octal dual supply tr anslating transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. it is designed to interface between a 3 v and 5 v bus in a mixed 3 v and 5 v supply environment. the device features an output enable input (pin oe ) for easy cascading and a send/receive input (pin dir) for direction control. pin oe controls the outputs so that the buses are effectively isolated. in suspend mode, when v cc(a ) is zero, there will be no current flow from one supply to the other supply. the a-outputs must be set 3-state and the voltage on the a-bus must be smaller than v diode (typical 0.7 v). v cc(a) ? v cc(b) , except in suspend mode. 2. features and benefits ? 5 v tolerant inputs/outputs, for interfacing with 5 v logic ? wide supply voltage range: ? 3 v bus (v cc(b) ): 1.5 v to 3.6 v ? 5 v bus ( v cc(a ) ): 1.5 v to 5.5 v ? cmos low-power consumption ? direct interface with ttl levels ? inputs accept voltages up to 5.5 v ? high-impedance when v cc(a ) = 0 v ? complies with jedec stand ard no. jesd8b/jesd36 ? esd protection: ? hbm jesd22-a114f exceeds 2000 v ? mm jesd22-a115-a exceeds 200 v ? multiple package options ? specified from ? 40 ? c to +85 ? c and ? 40 ? c to +125 ? c 74lvc4245a octal dual supply translating transceiver; 3-state rev. 7 ? 12 august 2011 product data sheet

[2] the term ?short data sheet? is explained in section ?definitions?. [3] the product status of device(s) described in this document may have changed since this document was published and may differ in case of multiple device s. the latest product status information is available on the internet at url http://www.nxp.com . 15.2 definitions draft ? the document is a draft versi on only. the content is still under internal review and subject to formal approval, which may result in modifications or additions. nxp semiconductors does not give any representations or warranties as to the accuracy or completeness of information included herein and shall hav e no liability for the consequences of use of such information. short data sheet ? a short data sheet is an extract from a full data sheet with the same product type number(s) and title. a short data sheet is intended for quick reference only and should not be relied upon to contain detailed and full information. for detailed and full information see the relevant full data sheet, which is available on request vi a the local nxp semiconductors sales office. in case of any inconsistency or conflict with the short data sheet, the full data sheet shall prevail. product specification ? the information and data provided in a product data sheet shall define the specification of the product as agreed between nxp semiconductors and its customer , unless nxp semiconductors and customer have explicitly agreed otherwis e in writing. in no event however, shall an agreement be valid in which the nxp semiconductors product is deemed to offer functions and qualities beyond those described in the product data sheet. 15.3 disclaimers limited warranty and liability ? information in this document is believed to be accurate and reliable. however, nxp semiconductors does not give any representations or warranties, expressed or implied, as to the accuracy or completeness of such information and shall have no liability for the consequences of use of such information. in no event shall nxp semiconductors be liable for any indirect, incidental, punitive, special or consequential damages (including - without limitation - lost profits, lost savings, business interruption, costs related to the removal or replacement of any products or rework charges) whether or not such damages are based on tort (including negligence), warranty, breach of contract or any other legal theory. notwithstanding any damages that customer might incur for any reason whatsoever, nxp semiconductors? aggregate and cumulative liability towards customer for the products described herein shall be limited in accordance with the terms and conditions of commercial sale of nxp semiconductors. right to make changes ?
