RD becomes a Motorola-style R/W control signal (R = 1, W = 0),
and WR becomes an active-low "M Enable" input.
TE7750, TE7751, TE7753 and TE7754 appear to be functionally
almost identical, though only the last two are pin-compatible.
TE7750, TE7751, TE7752, TE7753 and TE7754 appear to be nearly
identical functionally, though they have three different pinouts
(TE7751/TE7752 appear to be pin-compatible, as are TE7753/TE7754).
One known difference is that TE7753 resets all output latches to
"H" and TE7754 resets them to "L" (the latches can be written in
soft mode before the ports are set for output). TE7750 and TE7751
probably do either one or the other, but available documentation
is incomplete.
soft mode before the ports are set for output). TE7750, TE7751 and
TE7752 should do either one or the other, but available
documentation for these parts is incomplete.
