Description
The ITT75324 is a monolithic memory driver
with decode inputs designed for use with magnetic
memories;',The device contains two 400-
milliampere (source/sink) switch pairs, with
decoding capability from four address lines.
Two address inputs (8 and C) are used for
mode selection, i.e., source of sink. The other
two address inputs (A and D) are used for
switch-pair selection, i.e., output switch-pair
Y /Z or W/X respectively.
The sink circuit is composed of an inverting
switch with a transistor-transistor-Iogic (TTL)
input. The source circuit is an emitter-follower
driven from. a TTL input stage.
The ITI75324 is characterized for operation
from O·C to 70·C.
