Texas Instruments SN74LV595A 8-bit Shift Registers
Texas Instruments SN74LV595A 8-bit shift registers are designed for 2V to 5.5V VCC operation. TI SN74LV595A devices contain an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3-state outputs. Separate clocks are provided for both the shift and storage register. TI SN74LV595A shift registers are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.
