SN74LVCH245A (ACTIVE) Octal Bus Transceiver With 3-State Outputs

 

Description

The SN54LVCH245A octal bus transceiver is designed for 2.7-V to 3.6-V VCC operation, and the SN74LVCH245A octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.

Features

  • Operate From 1.65 V to 3.6 V
  • Inputs Accept Voltages to 5.5 V
  • Max tpd of 6.3 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
  • Support Mixed-Mode Signal Operation on All Ports (5-V Input/Output Voltage With
    3.3-V VCC)
  • Ioff Supports Live Insertion, Partial-Power-Down Mode, and Back-Drive Protection
  • Bus Hold on Data Inputs Eliminates the Need for External Pullup or Pulldown Resistors
  • Latch-Up Performance Exceeds 250 mA Per JESD 17
  • ESD Protection Exceeds JESD 22
    • 2000-V Human-Body Model (A114-A)
    • 200-V Machine Model (A115-A)
  • On Products Compliant to MIL-PRF-38535,
    All Parameters Are Tested Unless Otherwise Noted. On All Other Products, Production Processing Does Not Necessarily Include Testing of All Parameters.
