1 / 11 page © 2000 Fairchild Semiconductor Corporation DS500410 www.fairchildsemi.com October 2000 Revised October 2000 74LCXZ2245 Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs and Outputs and 26 Ω Series Resistors in B Outputs General Description The LCXZ2245 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 (2.7V 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 Ω series resistor in the B Port out- put helps reduce output overshoot and undershoot. The LCXZ2245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain- ing CMOS low power dissipation. When VCC is between 0 and 1.5V, the LCXZ2245 is on the high impedance state during power up or power down. This places the outputs in the high impedance (Z) state prevent- ing intermittent low impedance loading or glitching in bus oriented applications. Features s 5V tolerant inputs and outputs s 2.7V–3.6V VCC specifications provided s 7.0 ns tPD max (VCC = 3.3V), 10 µA ICC max s Power down high impedance inputs and outputs s Supports live insertion/withdrawal (Note 1) s ±12 mA output drive on the B Port (V CC = 3.0V) s Implements patented noise/EMI reduction circuitry s Latch-up performance exceeds 500 mA s Equivalent 26 Ω series resistor on all B Port 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.
