4-Bit Shift Register with TRI-STATE Outputs
General Description
The LS395 is a 4-bit shift register with TRI-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 over-
rides the synchronous operations and clears the register
An active LOW Output Enable (OE) input controls the TRI-
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
