74LVT2245; 74LVTH2245

3.3 V octal transceiver with 30 Ohm termination resistors; 3-state

The 74LVT2245; 74LVTH2245 is an 8-bit transceiver with 30 Ω termination resistors and 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

特性

  • 30 Ω output termination resistors

  • Octal bidirectional bus interface

  • 3-state buffers

  • Wide supply voltage range from 2.7 to 3.6 V

  • BiCMOS high speed and output drive

  • Output capability: +12 mA and -12 mA

  • TTL input and output switching levels

  • Overvoltage tolerant inputs to 5.5 V

  • Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs

  • Live insertion and extraction permitted

  • Direct interface with TTL levels

  • Power-up 3-state

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

  • 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:

    • MIL STD 883 method 3015: exceeds 2000 V

    • MM JESD22-A115-A exceeds 200 V (C = 200 pF, R = 0 Ω)
