Specialty Logic

oscillator drivercrystal oscillatorceramic resonatorSchmitt triggerVSSOP-81.65 V to 5.5 V

SN74LVC1404DCUR is a TI VSSOP-8 oscillator driver for crystal or ceramic-resonator clock circuits, with a separate Schmitt-trigger inverter for conditioning an oscillator signal.

Best for

  • Pierce crystal oscillator circuits
  • Ceramic-resonator clock generation
  • Oscillator signal conditioning with a Schmitt-trigger stage

Avoid if

  • A fully integrated crystal oscillator module is required
  • The selected resonator cannot meet the required start-up margin at the minimum supply voltage

Check before use

  • Crystal load capacitance and frequency
  • Series-resistor value and crystal drive level
  • CTRL power-up and power-down biasing
  • VSSOP-8 land pattern and 0.50 mm lead pitch
