Product: 13 × 74HC594S1613 (SO16) Key benefits - Ready quantity: 13 identical ICs included, convenient for small production runs, multiple prototypes, or spare inventory. - Compact form factor: SO16 surface-mount package (small-outline, 16-pin) saves PCB space and fits common SO16 footprints. - Proven logic-family compatibility: Part number follows the 74HC series naming, making it suitable for standard CMOS 74HC logic environments and common digital systems. - Serial-to-parallel capability: Suited to applications that require converting serial data into parallel outputs, reducing the number of MCU pins needed for multiple outputs. - Easy integration: Works with typical digital control signals and can be used in a variety of circuit designs that require shift-register-style functionality. What this product solves - Expands output capacity without redesigning the entire control subsystem — ideal when you need more outputs than your controller provides. - Saves PCB area compared with larger packages while remaining compatible with standard SO16 layouts. - Provides a matched set of components for consistent behavior across multiple boards or repeated designs. Important attributes - Model: 74HC594S1613 (13 pieces supplied) - Package: SO16 (small-outline, 16-pin surface-mount) - Function: Serial-to-parallel shift-register-style device consistent with 74HC logic family usage - Compatibility: Intended for digital logic applications and typical 74HC-family systems; integrates with common microcontrollers and digital circuitry - Quantity: Batch of 13 units, suitable for development, repair, or small-scale assembly Practical use scenarios - LED driver expansion: Use the ICs to convert serial control data into parallel outputs for driving LED arrays or indicator panels from a microcontroller with limited I/O. - Microcontroller output expansion: Add multiple parallel outputs for relays, solenoids, or status signals while minimizing MCU pin usage. - Prototyping and small-run production: Keep a matched set of 13 devices on hand for building and testing several boards or for replacing components during development. Notes for designers - Fits standard SO16 footprints and common surface-mount assembly processes. - Supplied quantity allows consistent component choice across multiple designs or as spares for field servicing.
