74LCX16821 - Low Voltage 20-Bit D-Type Flip-Flop

Description

The LCX16821 contains twenty non-inverting D-type flipflops 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.

Features

  • s 5V tolerant inputs and outputs s 2.3V.
  • 3.6V VCC specifications provided s 6.2 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 VC.
