Description
400 mil TSOP II
The GS74104A is a high speed CMOS Static RAM organized
as 1,048,576 words by 4 bits. Static design eliminates the need
for external clocks or timing strobes. The GS74104A operates
on a single 3.3 V power supply and all inputs and outputs are
TTL-compatible. The GS74104A is available in a RoHS-
compliant 400 mil TSOP Type-II package.
