Low Voltage Bidirectional Transceiver

74LCXZ2245 Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs and Outputs and 26Ω Series Resistors in B Outputs October 2000 Revised October 2000 74LCXZ2245 Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs and Outputs and 26Ω Series Resistors in B Outputs General Description The LCXZ2245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is designed for low voltage (2.7V and 3.3V) VCC applications with capability of interfacing 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 26Ω series resistor in the B Port output helps reduce output overshoot and undershoot. The LCXZ2245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining 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 preventing 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 (VCC = 3.0V) s Implements patented no.
