Text preview for : TTL-BIPOLAR_PROM-RAM_REFERENCE_GUIDE_V5.pdf part of Telepatch PROM Memory Types of memory used in Telapatch transceivers
Back to : TTL-BIPOLAR_PROM-RAM_REFE | Home
TTL/Bipolar PROM and RAM Reference Guide booklet V5 - print version
Also a few old CMOS PROMS
Added some modern PROM-pin and -speed compatible CMOS EPROM types, also some
military versions, which use a combined NiCr fuselink and CMOS technology.
TS = Tri-State output OC = Open Collector output
To be compatible with the rest of the world:
databits OUT now start with D0 (D-zero) and not anymore with O1
Hacked, copied, edited and extended by PE1ABR to give it a decent
shape and handy booklet form.
The main part is extracted from
http://www.arlo.net/vectorlist/archive/mbox/November_1997
and in detail: from the text part about the Bipolar PROMs List
