| Micrel, Inc. DUAL PARITY CHECKER/ GENERATOR DESCRIPTION SY100S360 SY100S360 FEATURES s s s s s s s s s s 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 75K 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 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 75K pull-down resistors.
