Description
A crystal controlled oscillator, with
output logic levels compatible with
ACMOS and TTL logic families. The
device is moulded in a plastic, 6-pin,
SMD, J leaded package that is ideal for
today's automated assembly environ-
ments.
Applications
• Compact, plastic-moulded surface
mountable package
• ACMOS and TTL compatible
• Tri-State output
• Ideally suited for use with contempo-
rary MPU's and custom ASIC's
