74LCX373

Low Voltage Octal Transparent Latch with 5V Tolerant Inputs and Outputs

The LCX373 consists of eight latches with 3-STATE outputs for bus organized system applications. The device is designed for low voltage (3.3V or 2.5V) VCC applications with capability of interfacing to a 5V signal environment.     The LCX373 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-3.6V VCC specifications provided
  • 8.0 ns tPD max (VCC = 3.3V), 10 µA ICC max
  • Power-down high impedance inputs and outputs
  • Supports live insertion/withdrawal (Note )
  • ±24 mA output drive (VCC = 3.0V)
  • Implements patented noise/EMI reduction circuitry
  • Latch-up performance exceeds JEDEC 78 conditions
  • ESD performance: Human Body Model > 2000V Machine Model > 200V
  • Leadless Pb-Free DQFN packageTo 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.
