Description
The 74HC595 SMD IC is a versatile, high-speed shift register device ideal for modern electronics projects. Designed for compact surface-mount applications, this chip provides an efficient way to expand output lines from microcontrollers, drive LEDs, displays, and control multiple devices using just a few data lines.
At its core, the 74HC595 contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register with 3-state output drivers. ti.com+2users.ece.utexas.edu+2 The input voltage range is wide—typically from 2 V to 6 V for the HC family—giving flexibility across many logic-level systems. ti.com+1
Outputs are designed to drive multiple loads (up to 15 LSTTL loads at 5 V) in the classic DIP or SMD packages. ti.com+1
Key features you’ll appreciate:
-
Serial-in → parallel-out makes it perfect for converting microcontroller data streams into many output pins (such as LED arrays or 7-segment displays).
-
3-state outputs (via OE pin) allow you to cascade multiple devices and control output enable with ease. users.ece.utexas.edu
-
Low power consumption (e.g., ICC ~80 µA typical) and high-speed switching (propagation delay ~13 ns typical) mean efficient and fast performance. ti.com+1
