Frequently Asked Questions (FAQ)

Q: Can the Texas Instruments CD74HC4094E directly replace the Parallax Inc. 602-00009 in existing designs?

A: Yes. Both devices are functionally equivalent 8-bit serial to parallel shift registers in 16-DIP packages with tri-state outputs. Pin configuration, electrical specifications, and supply voltage requirements are identical. Direct substitution is supported without circuit modification.

Q: What is the significance of the extended operating temperature range in the CD74HC4094E?

A: The CD74HC4094E operates from -55°C to 125°C, compared to the 602-00009 range of -40°C to 125°C. This extended lower temperature specification provides compatibility with applications requiring operation in colder environments. For applications within the -40°C to 125°C window, both devices perform equivalently.

Q: Are there any compliance or regulatory differences between these parts?

A: The CD74HC4094E is certified ROHS3 compliant and REACH unaffected. The 602-00009 compliance status is not specified. For applications subject to ROHS or REACH regulations, the CD74HC4094E is the appropriate selection.

Q: Does the 16-DIP package specification ensure mechanical compatibility?

A: Yes. Both the 602-00009 and CD74HC4094E use identical 16-DIP packaging with 0.300" (7.62mm) pitch. This ensures compatibility with standard DIP sockets, breadboards, and through-hole PCB layouts without mechanical modification.

Q: What is the supply voltage compatibility between these devices?

A: Both devices operate across the identical 2V to 6V supply voltage range. No power supply modifications are required when substituting the CD74HC4094E for the 602-00009.

Q: Why is the Parallax Inc. 602-00009 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. The Texas Instruments CD74HC4094E, as an active product with equivalent specifications, is the recommended alternative for new designs and ongoing component procurement.
