1 / 8 page © 2005 Fairchild Semiconductor Corporation DS500053 www.fairchildsemi.com August 1998 Revised June 2005 74LCXP16245 Low Voltage 16-Bit Bidirectional Transceiver with 5V Tolerant Inputs/Outputs and Pull-Down Resistors General Description The LCXP16245 contains sixteen non-inverting bidirec- tional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is designed for low volt- age (2.5V or 3.3V) VCC applications with capability of inter- facing to a 5V signal environment. The device is byte controlled. Each byte has separate control inputs which could be shorted together for full 16-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs disable both the A and B ports by placing them in a high impedance state. In addition, A and B port datapath pins have built-in resis- tors to GND allowing the pins to float without any increase in ICC current. This feature is intended to address modular and space constrained applications where additional space consumed by external resistors is not available. The LCXP16245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain- ing CMOS low power dissipation. Features s 5V tolerant inputs and outputs s 2.3V–3.6V VCC specifications provided s I/O pull-down resistors terminate inactive busses ensur- ing a stable bus state s 5.5 ns tPD max (VCC 3.3V), 20 PA ICC max s Power down high impedance inputs and outputs s Supports live insertion/withdrawal (Note 1) s r24 mA output drive (VCC 3.0V) s Implements patented noise/EMI reduction circuitry s Pinout compatible with 74 series 16245 s Latch-up performance exceeds 500 mA s ESD performance: Human body model ! 2000V Machine model ! 200V Note 1: To ensure the high-impedance state during power up or down OE should be tied to VCC through a pull-up resistor: the minimum value or the resistor is determined by the current-sourcing capability of the driver. Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
