DESCRIPTION
The SY100S366 is an ultra-fast 9-bit magnitude
comparator designed for use in high-performance ECL
systems. The device compares the arithmetic value of two
9-bit words and indicates whether one word is greater than
or equal to the other. The inputs on the device have 75KΩ
pull-down resistors.
