    ACTUAL SIZE
    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.
