74LCXR2245 Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs and Outputs and 26Ω Series Resistors on Both A and B Ports October 2000 Revised October 2000 74LCXR2245 Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs and Outputs and 26Ω Series Resistors on Both A and B Ports General Description Features The LCXR2245 contains eight non-inverting bidirectional5V tolerant inputs and outputs buffers with 3-STATE outputs and is intended for bus ori-2.3V–3.6V V specifications provided CC ented applications. The device is designed for low voltage 8.0 ns t max (V = 3.3V), 10 μA I max PD CC CC (2.5V and 3.3V) V applications with capability of interfac- CC Power down high impedance inputs and outputs ing to a 5V signal environment. The T/R input determines the direction of data flow through the device. The OE inputSupports live insertion/withdrawal (Note 1) disables both the A and B ports by placing them in a high ±12 mA output drive (V = 3.0V) CC impedance state. The 26Ω series resistor helps reduce Implements patented noise/EMI reduction circuitry output overshoot and undershoot. Latch-up performance exceeds 500 mA The LCXR2245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain-Equivalent 26Ω series resistor on all outputs ing CMOS low power dissipation.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 V through a pull-up resistor: the minimum value or the CC resistor is determined by the current-sourcing capability of the driver.
