SN74LS322AN datasheet

Description :

These 8-bit shift registers have multiplexed input/output data ports to accomplish full 8-bit datahandling in a single 20-pin package. Serial data may enter the shift-right register througheither D0 or D1 inputs as selected by the data select pin. A serial output is also provided. Synchronous parallel loading is achieved by taking the register enable and the S/Pinputs low. This places the three-state input/output ports in the data input mode. Data is entered on the low-to-high clock transition.The data extend function repeats the sign in the QA flip-flopduring shifting. An overriding clear input clears the internal registers when taken low whether the outputs are enabled or off. The output enable does not affect synchronous operation of the register.


1. Multiplexed Inputs/Outputs Provide Improved Bit Density
2. Sign Extend Function
3. Direct Overriding Clear
4. 3-State Outputs Drive Bus Lines Directly

74LS95 Datasheet PDF – 4-Bit Parallel-Access Shift Register

Part Number : 74LS95


Package : DIP, SOP 14 Pin,

74LS95 datasheet

Description :

These 4-bit register feature parallel and serial inputs, parallel outputs, mode control, and two clock inputs. The register have three modes of operation :

(1) Parallel (broadside) load
(2) Shift right (the direction Qa toward Qd)
(3) Shift left (the direction Qd toward Qa)

Parallel loading is accomplished by applying the four bits of data and taking the mode control input high. The data is loaded into the associated flip-flops and appears at the outputs after the high-to-low transistion of the clock-2 input. During loading, the entry of serial data is inhibited.
