The SY100S360 is a dual parity checker/generator and
is designed for use in high-performance ECL systems. The
inputs are segmented into two groups of nine inputs each
and the parity output is at a logic LOW when an even
number of inputs are at a logic HIGH. In each group, one of
the nine inputs (Ia, Ib) has a shorter propagation delay and,
therefore, is ideal as the expansion input for parity
generation of wider data.
A Compare output (C) is also provided which allows
comparison of two 8-bit words. A logic LOW on the C output
indicates a match. The inputs on this device have 75KΩ
pull-down resistors.
Max. propagation delay of 2200ps
IEE min. of –70mA
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
15% faster than Fairchild 300K
Approximately 30% lower power than Fairchild 300K
Function and pinout compatible with Fairchild F100K
Available in 24-pin CERPACK and 28-pin PLCC
packages
