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. A6 ■ 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 B5 B4 B3 ■ ■ ■ ■ SY100S366 Amendment: /0 Issue Date: July, 1999 SY100S366 Micrel BLOCK DIAGRAM A8 B8 A7 B7 A6 B6 A5 A>B B5 A=B A4 B4 B>A A3 B3 A2 B2 A1 B1 A0 B0 2 SY100S366 Micrel TRUTH TABLE(1) Inputs A8B8 A7B7 A6B6 A5B5 Outputs A4B4 A3B3 H L A8 = A8 = L H B8 B8 H L L H A8 = A8 = A8 = A8 = B8 B8 B8 B8 A7 = A7 = A7 = A7 = B7 B7 B7 B7 H L A6 = A6 = L H B6 B6 H L L H A8 = A8 = A8 = A8 = B8 B8 B8 B8 A7 = A7 = A7 = A7 = B7 B7 B7 B7 A6 = A6 = A6 = A6 = B6 B6 B6 B6 A5 = A5 = A5 = A5 = B5 B5 B5 B5 H L A4 = A4 = L H B4 B4 H L L H A8 = A8 = A8 = A8 = B8 B8 B8 B8 A7 = A7 = A7 = A7 = B7 B7 B7 B7 A6 = A6 = A6 = A6 = B6 B6 B6 B6 A5 = A5 = A5 = A5 = B5 B5 B5 B5 A4 = A4 = A4 = A4 = B4 B4 B4 B4 A3 = A3 = A3 = A3 = B3 B3 B3 B3 A8 = B8 A8 = B8 A8 = B8 A7 = B7 A7 = B7 A7 = B7 A6 = B6 A6 = B6 A6 = B6 A5 = B5 A5 = B5 A5 = B5 A4 = B4 A4 = B4 A4 = B4 A2B2 H L A2 = A2 = A3 = B3 A3 = B3 A3 = B3 L H B2 B2 A2 = B2 A2 = B2 A2 = B2 A1B1 H L A0B0 L H A1 = B1 A1 = B1 A1 = B1 H L L H A0 = B0 A>B B>A A=B H L H L L H L H H H H H H L H L L H L H H H H H H L H L L H L H H H H H H L H L L H L H H H H H H L L L H H H H H NOTE: 1.
