74LVT244B; 74LVTH244B

3.3 V octal buffer/line driver; 3-state

The 74LVT244B; 74LVTH244B 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

  • Speed upgrade of 74LVT244A

  • Wide supply voltage range from 2.7 to 3.6 V

  • BiCMOS high speed and output drive

  • Output capability: +64 mA and -32 mA

  • Direct interface with TTL levels

  • Overvoltage tolerant inputs to 5.5 V

  • 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

  • No bus current loading when output is tied to 5 V bus

  • Power-up 3-state

  • Live insertion and extraction permitted

  • IOFF circuitry provides partial Power-down mode operation

  • 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:

    • 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
