Product Description

The PI49FCT3805 is a 3.3V non-inverting clock driver and the PI49FCT3806 is a 3.3V inverting clock driver designed with two independent groups of buffers. These buffers have 3-state Output Enable inputs (active LOW) with a 1-in, 5-out configuration per group. Each clock driver consist of two banks of drivers, driving five outputs each from a standard TTL compatible CMOS input.


  • 3.3V version of PI49FCT805/806
  • Extremely low output skew: 0.5ns
  • Monitor ouput pin
  • Clock busing wih 3-state control
  • TTL input and CMOS output compatible
  • Industrial operation at –40°C to 85°C
  • Extremely low static power (1mW, typ.)
  • Hysteresis on all inputs
  • Packaging (Pb-free & Green available):
  •  20-pin 300-mil wide SOIC (S)
  •  20-pin 150-mil wide QSOP (Q)
  •  20-pin 209-mil wide SSOP (H)
