Texas Instruments SN74AUP1G125 Low-Power Single Bus Buffer Gates

Texas Instruments SN74AUP1G125 Low-Power Single Bus Buffer Gates offer a single-line driver with a 3-state output. When the output-enable (OE) input goes high, the output is disabled. The Input-Disable feature allows floating input conditions, while the Ioff supports partial-power-down mode operation. The high-impedance state is guaranteed during power up or power down only if the OE is tied to VCC through a pull-up resistor. The current-sinking capability of the driver determines the minimum value of the resistor.

Features

  • Available in the Texas Instruments NanoStar™ package
  • Low static-power consumption (ICC = 0.9µA Maximum)
  • Low dynamic-power consumption (Cpd = 4pF Typical at 3.3V)
  • Low input capacitance (CI = 1.5pF Typical)
  • Low noise – overshoot and undershoot <10% of VCC
  • Input-disable feature allows floating input conditions
  • Ioff Supports partial-power-down mode operation
  • Input hysteresis allows slow input transition and better switching noise immunity at the input
  • Wide operating VCC range of 0.8V to 3.6V
  • 3.6V I/O Tolerant to support mixed-mode signal operation
  • tpd = 4.6ns Maximum at 3.3V

Applications

  • Portable audio dock
  • BluRay™ players and home theaters
  • Personal Digital Assistant (PDA)
  • Telecom/server AC/DC supply, single controller, analog and digital
  • Client and enterprise Solid-State Drive (SSD)
  • LCD/Digital and High-Definition (HDTV)
  • Enterprise tablet
  • Wireless headsets, keyboards, and mice
