74LCXP16245: Low Voltage 16-Bit Bidirectional Transceiver with 5V Tolerant Inputs/Outputs and Pull-Down Resistors

The LCXP16245 contains sixteen non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing 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 resistors 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 maintaining CMOS low power dissipation.
