74LVT245

3.3 V octal transceiver with direction pin; 3-state

The 74LVT245 is an 8-bit transceiver with 3-state outputs. The device features an output enable (OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs

Features and benefits

  • Wide supply voltage range from 2.7 to 3.6 V
  • 3-state buffers
  • Octal bidirectional bus interface
  • Overvoltage tolerant inputs to 5.5 V
  • Direct interface with TTL levels
  • BiCMOS high speed and output drive
  • Output capability: +64 mA/-32 mA
  • Latch-up protection exceeds 500 mA per JESD78 class II level A
  • Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs
  • No bus current loading when output is tied to 5 V bus
  • Live insertion/extraction permitted
  • Power-up 3-state
  • IOFF circuitry provides partial Power-down mode operation
  • Complies with JEDEC standards JESD8C (2.7 V to 3.6 V)
  • ESD protection:
    • HBM JESD22-A114E exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
  • Specified from -40 °C to 85 °C
