DESCRIPTION The M54/74HC194 is a high speed CMOS 4 BIT PIPO 2 SHIFT REGISTER fabricated in silicon gate C MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. This SHIFT REGISTER is designed to incorporate virtually all of the features a system designer may want in a shift register. It features parallel inputs, parallel outputs, right shift and left shift serial inputs, clear line. The register has four distinct modes of operation : PARALLEL (broadside) LOAD ; SHIFT RIGHT (in the direction QA QD); SHIFT LEFT ; INHIBIT CLOCK (do nothing). Synchronous parallel loading is accomplished by applying the four data bits and taking both mode control inputs, S0 and S1 high. The data are loaded into their respective flip-flops and appear at the outputs after the positive transition of the CLOCK input. During loading, serial data flow is inhibited. Shift right is accomplished synchronously with the rising edge of the clock pulse when S0 is high and S1 is low. Serial data for this mode is entered at the SHIFT RIGHT data input. When S0 is low and S1 is high,data shifts left synchronously and new data is entered at the SHIFT LEFT serial input. Clocking of the flipflops is inhibited when both mode control inputs are low. The mode control inputs should be changed only when the CLOCK input is high. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
