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 V 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: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Specified from -40 °C to 85 °C
