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.

Max. propagation delay of 1500ps
IEE min. of –120mA
Industry standard 100K ECL levels
Extended supply voltage option:
VEE = –4.2V to –5.5V
Voltage and temperature compensation for improved
noise immunity
Internal 75KΩ input pull-down resistors
120% faster than Fairchild
Approximately 40% lower power than Fairchild
Function and pinout compatible with Fairchild F100K
Available in 24-pin CERPACK and 28-pin PLCC
packages
