Part Details:

on Both A and B P 74LCXR2245 -- Lo March 2008 74LCXR2245Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs o w rts V and Outputs and 26 Series Resistors on Both A and B Ports olta g Features General Description e Bidirectional 5V tolerant inputs and outputs The LCXR2245 contains eight non-inverting bidirectional 2.3V­3.6V V buffers with 3-STATE outputs and is intended for bus ori- CC specifications provided 8.0ns t = ented applications. The device is designed for low volt- PD max. (VCC 3.3V), 10µA ICC max. age (2.5V and 3.3V) V applications with capability of Power down high impedance inputs and outputs CC interfacing to a 5V signal environment. The T/R input Supports live insertion/withdrawal(1) determines the direction of data flow through the device. ±12mA output drive (V = CC 3.0V) The OE input disables both the A and B ports by placing T Implements patented noise/EMI reduction circuitry them in a high impedance state. The 26 series resistor ransceiver with 5V Latch-up performance exceeds 500mA helps reduce output overshoot and undershoot. Equivalent 26 series resistor on all outputs The LCXR2245 is fabricated with an advanced CMOS ESD performance: technology to achieve high speed operation while main- ­ Human body model > 2000V taining CMOS low power dissipation. ­ 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 Tolerant Inputs and Outputs and 26 determined by the current-sourcing capability of the driver.
