74LVT640

3.3 V Octal transceiver with direction pin; inverting; 3-state

The 74LVT640 is an 8-bit inverting 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

  • 3-state buffers

  • Wide supply voltage range from 2.7 to 3.6 V

  • Overvoltage tolerant inputs to 5.5 V

  • BiCMOS high speed and output drive

  • Direct interface with TTL levels

  • IOFF circuitry provides partial Power-down mode operation

  • Octal bidirectional bus interface

  • Input and output interface capability to systems at 5 V supply

  • Output capability: +64 mA and -32 mA

  • 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

  • Latch-up performance exceeds 500 mA per JESD 78 Class II Level B

  • Complies with JEDEC standards

    • JESD8C (2.7 V to 3.6 V)

  • ESD protection:

    • MIL STD 883 method 3015: exceeds 2000 V

    • MM JESD22-A115-A exceeds 200 V

  • Specified from -40 °C to +85 °C
