A crystal controlled, 3.3 or 5 volt, low
current oscillator designed to drive low
power, high performance microproces-
sors. The plastic-molded surface mount-
able package is ideal for today's auto-
mated assembly environments. J-leads
are compatible with EIA standard foot-
prints. The HCMOS device is capable of
driving both CMOS and TTL loads.
