74LVT244AD

3.3 V octal buffer/line driver; 3-state

The 74LVT244A; 74LVTH244A is an 8-bit buffer/line driver with 3-state outputs. The device can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE 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

  • Octal bus interface

  • 3-state buffers

  • Output capability: +64 mA and -32 mA

  • Wide supply voltage range from 2.7 to 3.6 V

  • Overvoltage tolerant inputs to 5.5 V

  • Direct interface with TTL levels

  • BiCMOS high speed and output drive

  • IOFF circuitry provides partial Power-down mode operation

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

  • Complies with JEDEC standard JESD8C (2.7 V to 3.6 V)

  • ESD protection:

    • HBM JESD22-A114E exceeds 2000 V

    • MM JESD22-A115-A exceeds 200 V

  • Specified from -40 °C to 85 °C

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
