The device is designed for low volt- A and B side outputs have equivalent 26Ω series age (2.5V or 3.3V) V applications with capability of inter- CC resistors facing to a 5V signal environment. The device is byte 5.3 ns t max (V = 3.3V), 20 μA I max controlled. Each byte has separate control inputs which PD CC CC could be shorted together for full 16-bit operation. The T/RPower down high impedance inputs and outputs inputs determine the direction of data flow through theSupports live insertion/withdrawal (Note 1) device. The OE inputs disable both the A and B ports by Flow through pinout placing them in a high impedance state. Implements patented noise/EMI reduction circuitry In addition, all A and B outputs include equivalent 26Ω Latch-up performance exceeds 500 mA (nominal) series resistors to reduce overshoot and under- shoot and are designed to sink/source up to 12 mA at ESD performance: V = 3.0V. CC Human body model > 2000V The LCXR162245 is fabricated with an advanced CMOS Machine model > 200V technology to achieve high speed operation while maintain- Note 1: To ensure the high-impedance state during power up or down OE ing CMOS low power dissipation. 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.
