  1. general description the 74cbtlv3245 is an 8-pole, single-throw bus switch. the device features a single output enable input (oe ) that controls eight switch chan nels. the switches are disabled when oe is high. schmitt-trigger action at contro l inputs makes the circuit tolerant of slower input rise and fall times. this devic e is fully specified for partial power-down applications using i off . the i off circuitry disables the output, preventing the damaging backflow current through the de vice when it is powered down. 2. features and benefits ? supply voltage range from 2.3 v to 3.6 v ? high noise immunity ? complies with jedec standard: ? jesd8-5 (2.3 v to 2.7 v) ? jesd8-b/jesd36 (2.7 v to 3.6 v) ? esd protection: ? hbm jesd22-a114f exceeds 2000 v ? mm jesd22-a115-a exceeds 200 v ? cdm aec-q100-011 revision b exceeds 1000 v ? 5 ? switch connection between two ports ? rail to rail switching on data i/o ports ? cmos low power consumption ? latch-up performance exceeds 250 ma per jesd78b class i level a ? i off circuitry provides partial power-down mode operation ? multiple package options ? specified from ? 40 ? cto+85 ? c and ? 40 ? cto+125 ? c 74cbtlv3245 8-bit bus switch with output enable rev. 2 ? 15 december 2011 product data sheet

applications that are described herein for any of these products are for illustrative purpos es only. nxp semiconductors makes no representation or warranty that such applications will be suitable for the specified use without further testing or modification. customers are responsible for the design and operation of their applications and products using nxp semiconductors products, and nxp semiconductors accepts no liability for any assistance with applications or customer product design. it is customer?s sole responsibility to determine whether the nxp semiconductors product is suitable and fit for the customer?s applications and products planned, as well as fo r the planned application and use of customer?s third party customer(s). customers should provide appropriate design and operating safeguards to minimize the risks associated with their applications and products. nxp semiconductors does not accept any liability related to any default, damage, costs or problem which is based on any weakness or default in the customer?s applications or products, or the application or use by customer?s third party customer(s). customer is responsible for doing all necessary testing for the customer?s applic ations and products using nxp semiconductors products in order to av oid a default of the applications and the products or of the application or use by customer?s third party customer(s). nxp does not accept any liability in this respect. limiting values ? stress above one or more limiting values (as defined in the absolute maximum ratings system of iec 60134) will cause permanent damage to the device. limiting values are stress ratings only and (proper) operation of the device at these or any other conditions above those given in the recommended operating conditions section (if present) or the characteristics sections of this document is not warranted. constant or repeated exposure to limiting values will permanently and irreversibly affect the quality and reliability of the device. terms and conditions of commercial sale ? nxp semiconductors products are sold subject to the gener al terms and conditions of commercial sale, as published at http://www.nxp.com/profile/terms , unless otherwise agreed in a valid written individual agreement. in case an individual agreement is concluded only the terms and conditions of the respective agreement shall apply. nxp semiconductors hereby expressly objects to applying the customer?s general terms and conditions with regard to the purchase of nxp semiconducto rs products by customer. no offer to sell or license ? nothing in this document may be interpreted or construed as an offer to sell products t hat is open for acceptance or the grant, conveyance or implication of any lic ense under any copyrights, patents or other industrial or intellectual property rights. export control ? this document as well as the item(s) described herein may be subject to export control regulations. export might require a prior authorization from competent authorities. document status [1] [2] product status [3] definition objective [short] data sheet development this document contains data from the objecti ve specification for product development. preliminary [short] data sheet qualification this document contains data from the preliminary specification. product [short] data sheet production this document contains the product specification.
