March 14, 1989

853-0139 96054

DESCRIPTION

The 82S191 and 82S191A are field

programmable, which means that

custom patterns are immediately

available by following the Signetics

Generic I fusing procedure. The 82S191

and 82S191A are supplied with all

outputs at logical Low. Outputs are

programmed to a logic High level at any

specified address by fusing the Ni-Cr

link matrix.

These devices include on-chip decoding

and 3 Chip Enable inputs for ease of

memory expansion. They feature

3-State outputs for optimization of word

expansion in bused organizations.

Ordering information can be found on

the following page.

The 82S191 and 82S191A devices are

also processed to military requirements

for operation over the military

temperature range. For specifications

and ordering information, consult the

Signetics Military Data Handbook.
