FEATURES
DESCRIPTION
■ 1100ps max. Propagation Delay A = B
The SY10/100E166 are 9-bit magnitude comparators
designed for use in new, high-performance ECL systems.
The E166 compares the binary value of two 9-bit words and
indicates whether one word is greater than or equal to the
other.
■ Extended 100E VEE range of –4.2V to –5.5V
■ Fully compatible with industry standard 10KH,
100K ECL levels
■ Internal 75KΩ input pulldown resistors
■ Fully compatible with Motorola MC10E/100E166
■ Available in 28-pin PLCC package
