74LVT640

3.3V Octal transceiver with direction pin; inverting (3-State)

The LVT640 is a high-performance BiCMOS product designed for VCC operation at 3.3V.

This device is an octal transceiver featuring 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

  • Cctal bidirectional bus interface
  • 3-State buffers
  • Output capability: +64 mA / -32 mA
  • TTL input and output switching levels
  • Input and output interface capability to systems at 5 V supply
  • Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs
  • Live insertion/extraction permitted
  • Power-up 3-State
  • No bus current loading when output is tied to 5 V bus
  • Latch-up protection exceeds 500mA per JEDEC Std 17
  • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model
