Chapter 5 - IC Specifications and Simple Interfacing
Chapter Overview
The driving force behind
the increased use of digital circuits has been the availability
of a variety of logic families. Integrated
circuits within a logic family are designed to interface
easily with one another.
For instance, in the TTL logic family
you may connect an output directly into the input of several
other TTL inputs with no extra parts. The designer can have
confidence that ICs from the same logic family will interface
properly.
Interfacing between
logic families and between digital ICs and the outside world
is a bit more complicated. Interfacing
can be defined as the design of the interconnections between
circuits that shift the levels of voltage and current to
make them compatible.
A fundamental knowledge of simple
interfacing techniques is required of technicians and engineers
who work with digital circuits. Most logic circuits are
of no value if they are not interfaced with 'real world'
devices.
