74HCT594S16-13

Shift Registers Overview

The 74HCT594S16-13 is an 8-bit shift register with an 8-bit output register manufactured by Diodes Incorporated. It operates on a 4.5V to 5.5V supply voltage and utilizes SOIC-16 surface-mount packaging. The device features Schmitt trigger inputs, CMOS low power consumption, and push-pull outputs capable of sourcing or sinking 8mA at VCC = 4.5V. Propagation delay from SHCP to Q7S is typically 18ns at 4.5V, while STCP to Qn delay is also typically 18ns under the same conditions.

Shift Registers Procurement Notes

Verify the specific package suffix matches the required footprint; S16 denotes SO-16. Confirm RoHS compliance status through official documentation as manufacturing processes may evolve. Ensure operating temperatures align with the specified -40°C to +125°C range. Check datasheet revisions for any updates to electrical characteristics or pin assignments before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when interfacing microcontrollers with multiple peripheral lines requiring serial-to-parallel expansion. The HCT logic family ensures compatibility with standard TTL voltage levels within the specified 4.5V to 5.5V range. Consider the propagation delays and maximum frequency limits when designing high-speed clocking schemes. Verify that the current sourcing and sinking capabilities meet the load requirements of the connected peripheral devices.

Shift Registers Part Context

This part belongs to the 74HCT series of advanced high-speed CMOS logic devices produced by Diodes Incorporated. It functions as an 8-bit shift register with storage registers, designed for general-purpose digital applications. The device is intended for surface-mount assembly and offers robust ESD protection exceeding industry standards for machine, human body, and charged device models.

Shift Registers Replacement Considerations

Compatible substitutes include other manufacturers' 74HCT594 variants in SOIC-16 packages. Verify pinout compatibility and electrical parameters such as propagation delay and output drive strength against the original specification sheet before substitution.
