| 9-BIT MAGNITUDE COMPARATOR SY10E166 SY100E166 FEATURES s 1100ps max. Propagation Delay A = B s Extended 100E VEE range of -4.2V to -5.5V s Fully compatible with industry standard 10KH, 100K ECL levels s Internal 75K input pulldown resistors s Fully compatible with Motorola MC10E/100E166 s Available in 28-pin PLCC package DESCRIPTION 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.
