74HC595D Shift register, 8-bit, 2 ... 6 V, SO-16

The 74HC/HCT595 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The “595" is an 8-stage serial shift register with a storage register and 3-state outputs. The shift register and storage register have separate clocks. Data is shifted on the positive-going transitions of the SHCP input. The data in each register is transferred to the storage register on a positive-going transition of the STCP input. If both clocks are connected together, the shift register will always be one clock pulse ahead of the storage register. The shift register has a serial input (DS) and a serial standard output (Q7’) for cascading. It is also provided with asynchronous reset (active LOW) for all 8 shift register stages. The storage register has 8 parallel 3-state bus driver outputs. Data in the storage register appears at the output whenever the output enable input (OE) is LOW.

Features - 8-bit serial input - 8-bit serial or parallel output - storage register with 3-state outputs - shift register with direct clear - 100 MHz (typ) shift out frequency - output capability: - parallel outputs; bus driver - serial output; standard - ICC category: MSI.

Applications - serial-to-parallel data conversion - remote control holding register
