SY10E151 SY100E151 FINAL 6-BIT D REGISTER FEATURES DESCRIPTION ■ 1100MHz toggle frequency ■ Extended 100E VEE range of –4.2V to –5.46V The SY10/100E151 offer 6 edge-triggered, high-speed, master-slave D-type flip-flops with differential outputs, designed for use in new, high-performance ECL systems. The two external clock signals (CLK1, CLK2) are gated through a logical OR operation before use as clocking control for the flip-flops. Data is clocked into the flip-flops on the rising edge of either CLK1 or CLK2 (or both). When both CLK1 and CLK2 are at a logic LOW, data enters the master and is transferred to the slave when either CLK1 or CLK2 (or both) go HIGH. The MR (Master Reset) signal operates asynchronously to make all Q outputs go to a logic LOW. ■ ■ ■ ■ Differential outputs Asynchronous Master Reset Dual clocks Fully compatible with industry standard 10KH, 100K ECL levels ■ Internal 75KΩ input pulldown resistors ■ Fully compatible with Motorola MC10E/100E151 ■ Available in 28-pin PLCC package BLOCK DIAGRAM R VCCO Q5 Q5 Q0 D CLK1 NC MR CLK2 D0 PIN CONFIGURATION Q0 25 24 23 22 21 20 19 Q1 27 17 Q4 VCC Q3 D2 2 D1 3 D0 4 Q2 28 15 14 13 12 5 Q3 16 PLCC TOP VIEW J28-1 1 Q4 D R D5 Q4 D4 D3 VEE Q3 D R D4 18 Q2 D R D3 26 6 7 8 9 Q3 Q2 Q2 10 11 VCCO D2 D5 Q0 R Q1 Q0 Q1 Q1 D NC VCCO D1 Q4 Q5 D R PIN NAMES Q5 CLK1 CLK2 Pin M R Function D0–D5 Data Inputs CLK1, CLK2 Clock Inputs MR Master Reset Q0–Q5 True Outputs Q0–Q5 Inverting Outputs VCCO VCC to Output Rev.: E 1 Amendment: /0 Issue Date: November 2002 SY10E151 SY100E151 Micrel TRUTH TABLES(1) Synchronous Operation Asynchronous Operation Inputs Inputs Output Output Dn CLK1 CLK2 MR Qn(t + 1) Dn CLK1 CLK2 MR Qn(t + 1) X X X H L L u L L L H u L L H L L u L L H L u L H X H u L Qn(t) X u H L Qn(t) X L L L Qn(t) NOTE: 1.
