74LCX32245 Low Voltage 32-Bit Bidirectional Transceiver with 5V Tolerant Inputs and Outputs November 2001 Revised June 2002 74LCX32245 Low Voltage 32-Bit Bidirectional Transceiver with 5V Tolerant Inputs and Outputs General Description Features The LCX32245 contains thirty-two non-inverting bidirec-5V tolerant inputs and outputs tional buffers with 3-STATE outputs and is intended for bus2.3V–3.6V V specifications provided CC oriented applications. The device is designed for low volt- 4.5 ns t max (V = 3.3V), 20 μA I max PD CC CC age (2.5V or 3.3V) V applications with capability of inter- CC Power down high impedance inputs and outputs facing to a 5V signal environment. The device is byte controlled. Each byte has separate control inputs whichSupports live insertion/withdrawal (Note 1) could be shorted together for full 32-bit operation. The T/R ±24 mA output drive (V = 3.0V) CC inputs determine the direction of data flow through the Uses patented noise/EMI reduction circuitry device. The OE inputs disable both the A and B ports by Latch-up performance exceeds 500 mA placing them in a high impedance state. The LCX32245 is fabricated with an advanced CMOS tech-ESD performance: nology to achieve high speed operation while maintaining Human body model > 2000V CMOS low power dissipation. Machine model > 200V Packaged in plastic Fine-Pitch Ball Grid Array (FBGA) 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.
