The 74VHC595M is an 8-bit shift register from ON Semiconductor. It is designed for high-speed operation, with a maximum frequency of 100 MHz. It is a serial-in, parallel-out shift register that can be used to perform multiplexing, down-counting, or other digital logic functions. The device has three-state outputs that can be controlled with a separate JK-type latch. The outputs are protected against damage from electrostatic discharges, voltage spikes, and inductive switching. This part is suited for applications including gate drivers, shift registers, and data latches.
