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