4-bit Bidirectional Universal Shift Register; • High Speed Operation: tpd (Clock to Q) = 12 ns typ (CL = 50 pF)\n• High Output Current: Fanout of 10 LSTTL Loads\n• Wide Operating Voltage: VCC = 2 to 6 V\n• Low Input Current: 1 µA max\n• Low Quiescent Supply Current: ICC (static) = 4 µA max ;

Description\nThis bidirectional 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, operating mode control inputs, and a direct overriding clear line. The register has four distinct modes of operation: parallel (broadside) load, shift right (in the direction QA toware QD); shift left; inhibit clock (do nothing).
