74VCX2245 Low Voltage Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs and 26: Series Resistors in B Outputs June 1999 Revised April 2005 74VCX2245 Low Voltage Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs and 26: Series Resistors in B Outputs General Description The VCX2245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The T/R input determines the direction of data flow. The OE input disables both the A and B ports by placing them in a high impedance state. The 74VCX2245 is designed for low voltage (1.4V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The VCX2245 is also designed with 26: series resistance in the B Port outputs. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus transceivers transmitters The 74VCX2245 is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining low CMOS power dissipation. Features s 1.4V - 3.6V VCC supply operation s 3.6V tolerant inputs and outputs s 26: series resistors in B Port outputs s Power-off high impedance inputs and outputs s Supports Live Insertion and Withdrawal (Note 1) s tPD (A to B) 4.4 ns max for 3.0V to 3.6V VCC s Static Drive (IOH/IOL B outputs): r12 mA @ 3.0V VCC s Uses patented Quiet Series noise/EMI reduction circuitry s Latchup performance exceeds JEDEC 78 conditions s ESD performance: Human body model ! 2000V ……
