description
These programmable array logic devices feature
high speed and a choice of either standard or
half-power devices. They combine Advanced
Low-Power Schottky technology with proven
titanium-tungsten fuses. These devices will
provide reliable, high-performance substitutes for
conventional TTL logic. Their easy
programmability allow for quick design of "custom"
functions and typically results in a more compact
circuit board. In addition, chip carriers are
available for further reduction in board space.
The Half-Power versions offer a choice of
operating frequency, switching speeds, and
power dissipation. In many cases, these
Half-Power devices can result in significant power
reduction from an overall system level.
The PAL16' M series is characterized for
operation over the full military temperature range
of 55
C to 125
C.
