74LCX16245 Low Voltage 16-Bit Bidirectional Transceiver with 5V Tolerant Inputs and Outputs February 1994 Revised April 2000 74LCX16245 Low Voltage 16-Bit Bidirectional Transceiver with 5V Tolerant Inputs and Outputs General Description The LCX16245 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. The LCX16245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. Features s 5V tolerant inputs and outputs s 2.3V–3.6V VCC specifications provided s 4.5 ns tPD max (VCC = 3.3V), 20 µA ICC max s Power down high impedance inputs and outputs s Supports live insertion/withdrawal (Note 1) s ±24 mA output drive (VCC = 3.0V) s Implements patented noise/EMI reduction circuitry 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 de...
