Description
The 5V S1800, S1850 and 3.3V S1803 are
crystal-controlled, low-current oscillators
providing precise rise and fall times to
drive high speed CMOS and TTL loads.
The sub-miniature, very low prole lead-
less ceramic packages have gold-plated
contact pads, ideal for today's pick-and-
place SMT environments. The S1850 is
a high output load version available to
80 MHz.
