Micrel, Inc. JK FLIP-FLOP FEATURES ■ ■ ■ ■ ■ SY10EL35 SY100EL35 SY10EL35 SY100EL35 DESCRIPTION 525ps propagation delay 2.2GHz toggle frequency High bandwidth output transistions Internal 75KΩ input pull-down resistors Available in 8-pin SOIC package The SY10/100EL35 are high-speed JK Flip-Flops. The J/K data enters the master portion of the flip-flop when the clock is LOW and is transferred to the slave and, thus, the outputs, upon a positive transition of the clock. The reset pin is asynchronous and is activated with a logic HIGH. TRUTH TABLE(1) J K R CLK Qn+1 L L L Z Qn L H L Z L H L L Z H H H L Z Qn X X H X L NOTE: 1. Z = LOW-to-HIGH transition.
