PLS100/PLS101
Programmable logic arrays
(16 × 48 × 8)

October 22, 1993 853–0308 11164
DESCRIPTION
The PLS100 (3-State) and PLS101 (Open
Collector) are bipolar, fuse Programmable
Logic Arrays (PLAs). Each device utilizes the
standard AND/OR/Invert architecture to
directly implement custom sum of product
equations.
Each device consists of 16 dedicated inputs
and 8 dedicated outputs. Each output is
capable of being actively controlled by any or
all of the 48 product terms. The True,
Complement, or Don’t Care condition of each
of the 16 inputs and be ANDed together to
comprise one P-term. All 48 P-terms can be
selectively ORed to each output.
The PLS100 and PLS101 are fully TTL
compatible, and chip enable control for
expansion of input variables and output
inhibit. They feature either Open Collector or
3-State outputs for ease of expansion of
product terms and application in
bus-organized systems.
Order codes are listed in the Ordering
Information Table.
