74LCX245 — Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs and Outputs December 2013 74LCX245 Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs and Outputs Features ■ 5V tolerant inputs and outputs ■ 2.3V to 3.6V VCC specifications provided ■ 7.0ns tPD max. (VCC = 3.3V), 10µA ICC max. ■ Power down high impedance inputs and outputs ■ Supports live insertion/withdrawal(1) ■ ±24mA output drive (VCC = 3.0V) ■ Implements proprietary noise/EMI reduction circuitry ■ Latch-up performance exceeds 500mA ■ ESD performance: – Human body model > 2000V – Machine model > 200V ■ Leadless DQFN package 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. General Description The LCX245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is designed for low voltage (2.5V and 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The T/R input determines the direction of data flow through the device. The OE input disables both the A and B ports by placing them in a high impedance state. The LCX245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
