Part Details:

74LCXZ245 October 2000 Revised March 2005 74LCXZ245 Low Low Voltage Bidirectional Transceiver Vo with 5V Tolerant Inputs and Outputs ltage Bid General Description Features The 74LCXZ245 contains eight non-inverting bidirectional s 5V tolerant inputs and outputs buffers with 3-STATE outputs and is intended for bus ori- s 2.3V­3.6V VCC specifications provided ented applications. The device is designed for low voltage ire s (2.5V and 3.3V) V 7.0 ns tPD max (VCC 3.3V), 10 PA ICC max CC applications with capability of interfac- cti ing to a 5V signal environment. The T/R input determines s Power down high impedance inputs and outputs the direction of data flow through the device. The OE input onal T s Supports live insertion/withdrawal (Note 1) disables both the A and B ports by placing them in a high s r24 mA output drive (VCC 3.0V) impedance state. s Implements patented noise/EMI reduction circuitry The 74LCXZ245 is fabricated with an advanced CMOS r technology to achieve high speed operation while maintain- s Latch-up performance exceeds 500 mA ansceiv ing CMOS low power dissipation. When V s CC is between 0V ESD performance: and 1.5V, the 74LCXZ245 is on the high impedance state Human body model ! 2000V during power up or power down. This places the outputs in Machine model ! 200V the high impedance (Z) state preventing intermittent low Note 1: To ensure the high-impedance state during power up or down, OE e impedance loading or glitching in bus oriented applications. should be tied to V r w CC through a pull-up resistor: the minimum value or the resistor is determined by the current-sourcing capability of the driver. i th 5V T
