Part # 74LS322 datasheet

Part Manufacturer: Motorola


Part Description: 74LS322

Part Details:

SN54/74LS322A 8-BIT SHIFT REGISTERSWITH SIGN EXTEND These 8-bit shift registers have multiplexed input/output data ports to accomplish full 8-bit data handling in a single 20-pin package. Serial data mayenter the shift-right register through either D0 or D1 inputs as selected by the 8-BIT SHIFT REGISTERS data select pin. A serial output is also provided. Synchronous parallel loading WITH SIGN EXTEND is achieved by taking the register enable and the S / P inputs low. This placesthe three-state input / output ports in the data input mode. Data is entered on LOW POWER SCHOTTKY the low-to-high clock transition. The data extend function repeats the sign inthe QA flip-flop during shifting. An overriding clear input clears the internalregisters when taken low whether the outputs are enabled or off. The outputenable does not affect synchronous operation of the register.· Multiplexed Inputs/Outputs Provide Improved Bit Density · J SUFFIX Sign Extend Function CERAMIC · Direct Overriding Clear CASE 732-03 · 3-State Outputs Drive Bus Lines Directly 20 1 (TOP VIEW) DATA SIGN N SUFFIX VCC SELECT EXTEND D1 B/QB D/QD F/QF H/QH Q/H CLOCK PLASTIC 20 19 18 17 16 15 14 13 12 11 CASE 738-03 20 1 DS SE D1 B/QB D/QD F/QF H/GH Q/H G CK DW SUFFIX S/P D0 A/QA C/QC E/QE G/QG OE CLR SOIC 20 CASE 751D-03
