74HC594S16-13

Shift Registers Overview

The Diodes Incorporated 74HC594S16-13 is an 8-bit shift register with an 8-bit output register, manufactured in the SO-16 surface-mount package. It operates on a high-speed CMOS process with a supply voltage range of 2.0V to 6.0V. The device features push-pull outputs capable of sourcing or sinking 8mA at VCC=4.5V. Key electrical parameters include a propagation delay (SHCP to Q7S) ranging from 14ns to 45ns depending on voltage and temperature, and a maximum frequency up to 109MHz at 6.0V. It includes Schmitt trigger inputs for noise immunity and meets ESD protection standards exceeding 2000V Human Body Model.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion using an eight-bit shift register and storage register architecture.
• Features independent active-low reset functions for both the shift register and storage register.
• Includes Schmitt trigger action at all inputs to improve noise immunity.
• Offers cascading capability via the Q7S serial data output pin.

Shift Registers Applications

• General purpose logic applications
• Serial to parallel data conversion
• Computer peripherals
• Appliances
• Industrial control systems

Shift Registers Procurement Notes

Verify the specific package suffix 'S16' corresponds to the SO-16 footprint required for your PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure operating conditions remain within the specified -40°C to +125°C temperature range. Check for any recent product change notifications that might affect pinout or electrical characteristics.

Shift Registers Selection Notes

Select this component when an 8-bit serial-in parallel-out configuration is required with independent clocking for shift and storage registers. The SO-16 package is suitable for standard surface-mount assembly processes. Consider the 2.0V to 6.0V operating range for compatibility with various logic families. Verify input voltage levels against the Schmitt trigger thresholds if interfacing with different logic standards.

Shift Registers Part Context

This part belongs to the 74HC594 family of high-speed CMOS logic devices produced by Diodes Incorporated. It is functionally equivalent to industry-standard 74HC594 components but packaged specifically in the SO-16 format for the '-13' ordering suffix variant. The device is designed for general-purpose digital logic applications requiring reliable data shifting and latching capabilities.

Shift Registers Replacement Considerations

Direct replacements include other manufacturers' 74HC594 devices in SO-16 packages. Verify pin compatibility and electrical specifications such as propagation delay and output drive current before substitution. Ensure the alternative component supports the same voltage range and temperature ratings.

Shift Registers FAQ

What is the function of the Q7S pin?

Q7S is the serial data output used for cascading information between multiple 74HC594 devices.

How are the shift and storage registers controlled?

Data enters the shift register on the rising edge of SHCP and moves to the storage register on the rising edge of STCP. Both registers have independent active-low reset inputs (SHR and STR).
