74LCXZ16245 March 2002 Revised June 2005 74LCXZ16245 Low Low Voltage 16-Bit Bidirectional Transceiver with 5V Tolerant Inputs and Outputs Volt General Description Features age 16- The LCXZ16245 contains sixteen non-inverting bidirec- s 5V tolerant inputs and outputs tional buffers with 3-STATE outputs and is intended for bus s 2.7V­3.6V VCC specifications provided oriented applications. The device is designed for low volt- s age (2.7V or 3.3V) V 4.5 ns tPD max (VCC 3.3V), 20 PA ICC max CC applications with capability of inter- Bit facing to a 5V signal environment. The device is byte s Power-down high impedance inputs and outputs Bi controlled. Each byte has separate control inputs which s Supports live insertion/withdrawal (Note 1) could be shorted together for full 16-bit operation. The T/R s r24 mA output drive (VCC 3.0V) dir inputs determine the direction of data flow through thedevice. The OE inputs disable both the A and B ports by s Implements patented noise/EMI reduction circuitry ect placing them in a high impedance state. s Latch-up performance conforms to the requirements of JESD78 ional When VCC is between 0V and 1.5V, the LCXZ16245 is onthe high impedance state during power-up or power-down. s ESD performance: This places the outputs in the high impedance (Z) state Human body model ! 2000V T preventing intermittent low impedance loading or glitching Machine model ! 200V r in bus oriented applications. anscei Note 1: To ensure the high-impedance state during power up or down, OE The LCXZ16245 is fabricated with an advanced CMOS should be tied to VCC through a pull-up resistor: the minimum value or the technology to achieve high speed operation while maintain- resistor is determined by the current-sourcing capability of the driver. ing CMOS low power dissipation. ver wit Ordering Code:
