Octal Buffer/Driver With 3-State Outputs

 

Description

These octal bus buffers are designed for 1.65-V to 3.6-V VCC operation. The SN74LVC244A devices are designed for asynchronous communication between data buses.

Features

  • Operates From 1.65 V to 3.6 V
  • Inputs Accept Voltages to 5.5 V
  • Specified From –40°C to +85°C and –40°C to +125°C
  • Maximum tpd of 5.9 ns at 3.3 V
  • Typical VOLP (Output Ground Bounce) < 0.8 V at VCC = 3.3 V, TA = 25°C
  • Typical VOHV (Output VOH Undershoot) > 2 V at VCC = 3.3 V, TA = 25°C
  • Supports Mixed-Mode Signal Operation on All Ports (5-V Input or Output Voltage With 3.3-V VCC)
  • Ioff Supports Live Insertion, Partial-Power-Down Mode, and Back-Drive Protection
  • Can Be Used as a Down Translator to Translate Inputs From a Maximum of 5.5 V Down to the VCC Level
  • Available in Ultra Small Logic QFN Package (0.5 mm Maximum Height)
  • Latch-Up Performance Exceeds 250 mA Per JESD 17
  • ESD Protection Exceeds JESD 22
