features description/ordering information sn74alvch16245 16-bit bus transceiver with 3-state outputs sces015l ? july 1995 ? revised november 2005 member of the texas instruments widebus? family operates from 1.65 v to 3.6 v max t pd of 3 ns at 3.3 v 24-ma output drive at 3.3 v bus hold on data inputs eliminates the need for external pullup/pulldown resistors latch-up performance exceeds 250 ma per jesd 17 esd protection exceeds jesd 22 - 2000-v human-body model (a114-a) - 200-v machine model (a115-a) this 16-bit (dual-octal) noninverting bus transceiver is designed for 1.65-v to 3.6-v v cc operation. the sn74alvch16245 is designed for asynchronous communication between two data buses. the logic levels of the direction-control (dir) input and the output-enable ( oe) input activate either the b-port outputs or the a-port outputs or place both output ports into the high-impedance mode. the device transmits data from the a bus to the b bus when the b-port outputs are activated, and from the b bus to the a bus when the a-port outputs are activated. the input circuitry on both a and b ports is always active and must have a logic high or low level applied to prevent excess i cc and i ccz . xxxxxx to ensure the high-impedance state during power up or power down, oe should be tied to v cc through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. active bus-hold circuitry holds unused or undriven inputs at a valid logic state. use of pullup or pulldown resistors with the bus-hold circuitry is not recommended. please be aware that an important notice concerning availability, standard warranty, and use in critical applications of texas instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. widebus is a trademark of texas instruments. production data information is current as of publication date. copyright ? 1995?2005, texas instruments incorporated products conform to specifications per the terms of the texas instruments standard warranty. production processing does not necessarily include testing of all parameters. www .ti.com dgg, dgv , or dl p ackage (t op view) 12 3 4 5 6 7 8 9 10 1 1 1213 14 15 16 17 18 19 20 21 22 23 24 4847 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 1dir 1b11b2 gnd 1b31b4 v c c 1b51b6 gnd 1b71b8 2b1 2b2 gnd 2b32b4 v c c 2b52b6 gnd 2b72b8 2dir 1oe 1a11a2 gnd 1a3 1a4 v c c 1a51a6 gnd 1a7 1a8 2a1 2a2 gnd 2a3 2a4 v c c 2a52a6 gnd 2a7 2a8 2oe
