SY10E431 SY100E431 3-BIT DIFFERENTIAL FLIP-FLOP Micrel, Inc. SY10E431 SY100E431 DESCRIPTION FEATURES ■ Differential D, clock and Q The SY10/100E431 are 3-bit flip-flops with differential clock, data input and data output. The asynchronous Set and Reset controls are edgetriggered rather than level controlled. This allows the user to rapidly set or reset the flip-flop and then continue clocking at the next clock edge without the necessity of de-asserting the set/reset signal (as would be the case with a level controlled set/reset). The E431 is also designed with larger internal swings, an approach intended to minimize the time spent crossing the threshold region and thus reduces the metastability susceptibility window. ■ Extended 100E VEE range of –4.2V to –5.5V ■ VBB output for single-ended use ■ 1100MHz min. toggle frequency ■ Edge-triggered asynchronous set and reset ■ Fully compatible with Motorola MC10E/100E431 ■ Available in 28-pin PLCC package PIN NAMES BLOCK DIAGRAM S0 Pin Function D[0:2], D[0:2] Differential Data Inputs CLK[0:2], CLK[0:2] Differential Clock Inputs S[0:2] Edge Triggered Set Inputs R[0:2] Edge Triggered Reset Inputs R0 VBB VBB Reference Output S1 Q[0:2], Q[0:2] Differential Data Outputs VCCO VCC to Output D0 D0 D CLK0 CLK0 D1 D1 S Q Q0 Q Q0 R D CLK1 CLK1 S Q Q1 Q Q1 R TRUTH TABLE(1) R1 Dn CLKn Rn Sn Qn S2 L Z L L L H Z L L H X L Z L L X L L Z H D2 D2 D CLK2 CLK2 S R Q Q2 Q Q2 NOTE: 1.

These set-up times define the minimum time the CLK or SET/RESET input must wait after the assertion of the RESET/SET input to assure the proper operation of the flip-flop. 2. Within-device skew is defined as identical transitions on similar paths through a device. 3. Minimum input swing for which AC parameters are guaranteed.
