          Description
          A crystal controlled, low current, low
          jitter and high frequency oscillator with
          precise rise and fall times demanded in
          networking applications. The tri-state
          function on the NTH enables the output
          to go high impedance. Device is pack-
          aged in a 14 or an 8-pin DIP compatible
          resistance welded, all metal grounded
          case to reduce EMI. True SMD DIL14
          versions for IR reflow are available, se-
          lect option "S" in part number builder.
          See separate data sheet for SMD package
          dimensions.
