74VCX245 Low Voltage Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs June 1999 Revised April 2005 74VCX245 Low Voltage Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs General Description The VCX245 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 74VCX245 is designed for low voltage (1.4V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The 74VCX245 is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining low CMOS power dissipation. Features s 1.4V to 3.6V VCC supply operation s 3.6V tolerant inputs and outputs s Power-off high impedance inputs and outputs s Supports Live Insertion and Withdrawal (Note 1) s tPD 3.5 ns max for 3.0V to 3.6V VCC s Static Drive (IOH/IOL) r24 mA @ 3.0V VCC s Uses patented noise/EMI reduction circuitry s Latchup performance exceeds 300 mA s ESD performance: Human body model ! 2000V Machine model ! 200V s Leadless DQFN Pb-Free package Note 1: To ensure the high impedance state during power up and power down, OEn should be tied to VCC through a pull up resistor. The minimum value of the resistor is determined by the current sourcing capability of the driver. Ordering Code: Order Number 74VCX245WM (Note 2) 74VCX245BQX (Note 3) 74VCX245MTC (Note 2) Pac……
