74LVTH32245

General description

The 74LVTH32245 is a high-performance BiCMOS product designed for V_CC operation at 3.3 V. The 74LVTH32245 is a 32-bit transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The device features four output enable (nOE) inputs for easy cascading and four send/receive (nDIR) inputs for direction control. Pin nOE controls the outputs so that the buses are effectively isolated. Bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs.

Features

• 32-bit bidirectional bus interface
• 3-state buffers
• Output capability: +64 mA and -32 mA
• TTL input and output switching levels
• Input and output interface capability to systems at 5 V supply
• Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs
• Live insertion and extraction permitted
• Power-up 3-state
• No bus current loading when output is tied to 5 V bus
• Latch-up protection:
  • JESD78 Class II level A exceeds 500 mA
• ESD protection:
  • HBM JESD22-A114E exceeds 2000 V
  • MM JESD22-A115-A exceeds 200 V
