4-BIT SHIFT REGISTER WITH 3-STATE OUTPUTS
4-BIT SHIFT REGISTER
WITH 3-ST ATE OUTPUTSThe SN74LS395 is a 4-Bit Register with 3-state outputs and can operate
in either a synchronous parallel load or a serial shift-right mode, as
determined by the Select input. An asynchronous active LOW Master Reset
(MR) input overrides the synchronous operations and clears the register. An
active HIGH Output Enable (OE) input controls the 3-state output buffers, but
does not interfere with the other operations. The fourth stage also has a
conventional output for linking purposes in multi-stage serial operations. Shift Left or Parallel 4-Bit Register 3-State Outputs Input Clamp Diodes Limit High-Speed Termination Effects
