3.3 V octal transceiver with direction pin (3-state)

The 74LVT245B is a high-performance BiCMOS product designed for VCC operation at 3.3 V.

This device is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features an output enable (OE) input for easy cascading and a direction (DIR) input for direction control.

Features and benefits

  • 3-state buffers
  • Octal bidirectional bus interface
  • Input and output interface capability to systems at 5 V supply
  • TTL input and output switching levels
  • Output capability: +64 mA/-32 mA
  • Latch-up protection exceeds 500 mA per JEDEC Std 17
  • ESD protection:
    • HBM JESD22-A114E exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
  • Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs
  • Live insertion/extraction permitted
  • Power-up 3-state
  • No bus current loading when output is tied to 5 V bus
