74LCXP16245 Low Voltage 16-Bit Bidirectional Transceiver with 5V Tolerant Inputs/Outputs and Pull-Down Resistors August 1998 Revised April 2001 74LCXP16245 Low Voltage 16-Bit Bidirectional Transceiver with 5V Tolerant Inputs/Outputs and Pull-Down Resistors General Description Features The LCXP16245 contains sixteen non-inverting bidirec-5V tolerant inputs and outputs tional buffers with 3-STATE outputs and is intended for bus2.3V–3.6V V specifications provided CC oriented applications. The device is designed for low volt- I/O pull-down resistors terminate inactive busses ensur- age (2.5V or 3.3V) V applications with capability of inter- CC ing a stable bus state facing to a 5V signal environment. The device is byte 5.5 ns t max (V = 3.3V), 20 μA I max PD CC CC controlled. Each byte has separate control inputs which could be shorted together for full 16-bit operation. The T/RPower down high impedance inputs and outputs inputs determine the direction of data flow through theSupports live insertion/withdrawal (Note 1) device. The OE inputs disable both the A and B ports by ±24 mA output drive (V = 3.0V) CC placing them in a high impedance state. Implements patented noise/EMI reduction circuitry In addition, A and B port datapath pins have built-in resis- Pinout compatible with 74 series 16245 tors to GND allowing the pins to float without any increase in I current. This feature is intended to address modular CCLatch-up performance exceeds 500 mA and space constrained applications where additional spaceESD performance: consumed by external resistors is not available.
