8-BIT SHIFT REGISTER Micrel, Inc. FEATURES ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ SY100S341 SY100S341 DESCRIPTION The SY100S341 offer eight D-type, edge-triggered flipflops with both individual inputs for parallel operation as well as serial inputs for bidirectional shifting, and are designed for use in high-performance ECL systems. Data is clocked into the flip-flops on the rising edge of the clock. The mode of operation is selected by two Select inputs (S0, S1) which determine if the device performs a shift, hold or parallel entry function, as described in the Truth Table. The inputs on these devices have 75KΩ pull-down resistors. Max. shift frequency of 600MHz Max. Clock to Q delay of 1200ps IEE min. of –150mA 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 70% faster than Fairchild 300K at lower power Function and pinout compatible with Fairchild F100K Available in 24-pin CERPACK and 28-pin PLCC packages PIN NAMES Label Function CP Clock Pulse Input S0 — S1 Select Inputs D0 — D7 Serial Inputs P0 — P7 Parallel Inputs Q0 — Q7 Data Outputs VEES VEE Substrate VCCA VCCO for ECL Outputs M9999-032206 [email protected] or (408) 955-1690 Rev.: H 1 Amendment: /0 Issue Date: March 2006 SY100S341 Micrel, Inc.
