DESCRIPTION:
The IDT10474(10A474), IDT100474(100A474) and
IDT101474(101A474) are 4,096-bit high-speed BiCMOS ECL
static random access memories organized as 1Kx4, with
separate data inputs and outputs. All I/Os are fully compatible
with ECL levels.
These devices are part of a family of asynchronous four-
bit-wide ECL SRAMs. This device is available in both the
traditional corner-power pinout, and "revolutionary" center-
power pin configurations. Because they are manufactured in
BiCMOS technology, power dissipation is greatly reduced
over equivalent bipolar devices. Low power operation pro-
vides higher system reliability and makes possible the use of
the plastic SOJ package for high-density surface mount
assembly.
The fast access time and guaranteed Output Hold time
allow greater margin for system timing variation. DataIN setup
time specified with respect to the trailing edge of Write Pulse
eases write timing allowing balanced Read and Write cycle
times.
