DESCRIPTION
FEATURES
PIN CONFIGURATIONS
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.
• I/O propagation delay: 50ns (max.)
• Power dissipation: 600mW (typ.)
• Input loading: –100µA (max.)
• Chip Enable input

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
