74LV4094DB,112

Shift Registers Overview

The 74LV4094 is an 8-stage shift-and-store bus register featuring a serial-in/serial or parallel-out architecture with a storage register and 3-state outputs. It operates over a supply voltage range of 1.0 V to 3.6 V, accepting TTL input levels between VCC = 2.7 V and VCC = 3.6 V. The device includes separate clocks for the shift and storage registers, along with serial outputs (QS1 and QS2) for cascading. It complies with JEDEC standards JESD8-7, JESD8-5, and JESD8C.

Shift Registers Feature Summary

• Optimized for low voltage applications across a wide supply voltage range
• Features direct interface capabilities with TTL levels
• Includes clamp diodes on inputs to allow interfacing to voltages exceeding VCC
• Provides latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register

Shift Registers Procurement Notes

Verify the specific package type required, as the datasheet lists SO16 (SOT109-1) and TSSOP16 (SOT403-1). Confirm that the ordering suffix matches the desired package variant. Ensure compatibility with the target operating temperature range, which extends up to +125 °C. Check for any recent product change notices regarding pinning or electrical characteristics before finalizing procurement.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with independent storage and output enable functions is needed. It is suitable for designs requiring cascading via dual serial outputs. Consider the low power CMOS dissipation and ESD protection ratings. Verify that the input voltage levels align with the system's logic family, particularly if utilizing TTL levels at higher supply voltages.
