1 / 8 page © 2005 Fairchild Semiconductor Corporation DS500581 www.fairchildsemi.com May 2002 Revised June 2005 74LCXH16245 Low Voltage 16-Bit Bidirectional Transceiver with Bushold General Description The LCXH16245 contains sixteen non-inverting bidirec- tional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is designed for low volt- age (2.5V or 3.3V) VCC applications with capability of inter- facing to a 5V signal environment. The device is byte controlled. Each byte has separate control inputs which could be shorted together for full 16-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs disable both the A and B Ports by placing them in a high impedance state. The LCXH16245 data inputs include active bushold cir- cuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level. The LCXH16245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain- ing CMOS low power dissipation. Features s 2.3V–3.6V VCC specifications provided s 4.5 ns tPD max (VCC 3.3V), 20 PA ICC max s Power-down high impedance outputs s Bushold on inputs eliminates the need for external pull-up/pull-down resistors s r24 mA output drive (VCC 3.0V) s Implements patented noise/EMI reduction circuitry s Latch-up performance conforms to the requirements of JESD78 s ESD performance: Human body model ! 2000V Machine model ! 200V s Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA) Ordering Code: Note 1: Ordering Code “G” indicates Trays. Note 2: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
