74LVC595A Datasheet | NXP Semiconductors

Rev. 01 - 29 May 2007 .. 8-bit serial-in/serial-out or parallel-out shift register; 3-state Product data sheet 1. General description The 74LVC595A is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. Both the shift and storage register have separate clocks. The input can be driven from either 3.3 V or 5 V devices. This feature allows the use of this device in a mixed 3.3 V and 5 V environment. This device is fully specified for partial Power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down. Data is shifted...
