SN74LS590 具有输入锁存器的移位寄存器

The SN74LS590 comes in a 16-pin package and consists of an 8-bit storage latch feeding a parallel-in, serial-out 8-bit shift register. Both the storage register and shift register have positive-edge triggered clocks. The shift register also has direct load (from storage) and clear inputs.

The SN74LS590 comes in a 20-pin package and has all the features of the SN74LS590 plus 3-state I/O ports that provide parallel shift register outputs and also has multiplexed serial data inputs
