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 75K pull-down resistors.
