1 / 10 page © 2005 Fairchild Semiconductor Corporation DS500361 www.fairchildsemi.com October 2000 Revised March 2005 74LCXR2245 Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs and Outputs and 26 : Series Resistors on Both A and B Ports General Description The LCXR2245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus ori- ented applications. The device is designed for low voltage (2.5V and 3.3V) VCC applications with capability of interfac- ing to a 5V signal environment. The T/R input determines the direction of data flow through the device. The OE input disables both the A and B ports by placing them in a high impedance state. The 26 : series resistor helps reduce out- put overshoot and undershoot. The LCXR2245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain- ing CMOS low power dissipation. Features s 5V tolerant inputs and outputs s 2.3V–3.6V VCC specifications provided s 8.0 ns tPD max (VCC 3.3V), 10 PA ICC max s Power down high impedance inputs and outputs s Supports live insertion/withdrawal (Note 1) s r12 mA output drive (VCC 3.0V) s Implements patented noise/EMI reduction circuitry s Latch-up performance exceeds 500 mA s Equivalent 26 : series resistor on all outputs s ESD performance: Human body model ! 2000V Machine model ! 200V Note 1: To ensure the high-impedance state during power up or down, OE should be tied to VCC through a pull-up resistor: the minimum value or the resistor is determined by the current-sourcing capability of the driver. Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
