Description
A crystal controlled, low current oscilla-
tor providing precise rise and fall times to
drive High Speed HCMOS and NMOS
microprocessors. The tri-state function
on the NTH enables the output to go high
impedance. Device is packaged in a 14 or
an 8-pin DIP compatible resistance
welded, all metal grounded case, to re-
duce EMI.
