CD74HC4094PWRG4

Shift Registers Overview

The CD74HC4094PWRG4 is a high-speed CMOS logic device manufactured by Texas Instruments, functioning as an 8-stage shift-and-store bus register with three-state outputs. It integrates an 8-bit serial-in parallel-out (SIPO) shift register and an 8-bit storage latch within a single package. The component operates on a supply voltage range of 2V to 6V and supports surface-mount installation in a TSSOP-16 package. It features two serial output pins for cascading capabilities and includes an output enable control for bus sharing.

Shift Registers Feature Summary

• Integrates an 8-bit shift register and an 8-bit storage latch for serial-to-parallel data conversion
• Provides tri-state parallel outputs controlled by an output enable pin for bus system compatibility
• Features dual serial outputs to facilitate flexible cascading configurations across multiple devices

Shift Registers Applications

• Microcontroller I/O expansion systems requiring additional digital output lines
• LED display driver circuits utilizing serial data input and parallel latching
• Data acquisition systems converting serial sensor streams to parallel formats

Shift Registers Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free and RoHS compliance status. Ensure the TSSOP-16 package variant matches your PCB footprint requirements. Confirm the operating temperature range aligns with your specific application environment before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when designing systems that require expanding microcontroller GPIO pins through serial communication protocols. The tri-state output capability allows multiple registers to share a common data bus without electrical conflicts. Verify that the 2V to 6V supply voltage range is compatible with your system's power rails and logic levels.

Shift Registers Part Context

This device belongs to the Texas Instruments 74HC series of high-speed CMOS logic integrated circuits. The HC series is designed to be pin-compatible with older TTL logic families while offering significantly lower power consumption. The CD prefix indicates commercial grade temperature rating, distinguishing it from military or automotive qualified variants within the same functional family.

Shift Registers Replacement Considerations

Direct replacements include the CD74HC4094M96 and SN74HC4094DR. Verify package dimensions and pinout compatibility when substituting these alternatives. Ensure the replacement part maintains the same 8-bit SIPO functionality and tri-state output characteristics.
