Thru-Hole, 5V
Our thru-hole fixed frequency 5 volt oscillators
embody 25 years of design and manufacturing
knowhow. They are available in full-size and
half size packages, all hermetically sealed
with welded stainless steel cover. These 5V
thru-hole oscillators are designed for everyday
stresses of 0°C to 70°C operation and extended
frequency selection of 1 KHz to 175 MHz.
Higher (5V) operation ensures superior output
loading and faster rise/fall times characteristics.
FIXED FREQUENCY
These oscillators have a full range of seven stability choices,
with choice of tristate or “hard zero.”
TRISTATE
Tristate models are tristated from Pin 1. When Pin 1 is
floating or “1”, the output is normal. When Pin 1 is returned
to “0”, the output is tristated.
HARD ZERO
Hard Zero models output a hard zero when Pin 1 is returned
to “0”.
