74LCX245

Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs and Outputs

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.

Features

  • 5V tolerant inputs and outputs
  • 2.3V to 3.6V VCC specifications provided
  • 7.0 ns tPD max (VCC = 3.3V), 10 µA ICC max
  • Power down high impedance inputs and outputs
  • Supports live insertion/withdrawal (Note 1)
  • ±24 mA output drive (VCC = 3.0V)
  • Implements patented noise/EMI reduction circuitry
  • Latch-up performance exceeds 500 mA
  • ESD performance:Human body model > 2000VMachine model > 200V
  • Leadless DQFN Pb-Free package
