74LVT126

3.3 V quad buffer; 3-state

The 74LVT126 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). A LOW 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. This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.

特性

  • Quad bus interface

  • 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

  • Output capability: +64 mA and -32 mA

  • Direct interface with TTL levels

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

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

  • Live insertion and extraction permitted

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

  • Power-up 3-state

  • IOFF circuitry provides partial Power-down mode operation

  • 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: 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
