74LV4094D,112

Shift Registers Overview

The Nexperia 74LV4094D,112 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. It operates within a supply voltage range of 1.0 V to 3.6 V and accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V. The device features separate clocks for the shift and storage registers, along with serial outputs (QS1 and QS2) for cascading. Data shifts on LOW-to-HIGH transitions of the CP input. The package is SO16 plastic small outline (SOT109-1), with dimensions of 10 mm length, 4 mm width, and 1.75 mm height. Operating temperature ranges from -40 °C to +125 °C.

Shift Registers Feature Summary

• Optimized for low voltage applications over a wide supply voltage range
• Features separate clocks for shift and storage registers
• Includes clamp diodes on inputs for interface flexibility
• Provides dual serial outputs to support cascading configurations

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74LV4094 family includes alternative packages such as TSSOP16. Confirm that the component meets the necessary environmental compliance standards for the target application. Ensure the design accounts for the specified operating temperature range and supply voltage limits to maintain reliable performance.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with independent storage and shift clocking is required. It is suitable for designs needing direct interface with TTL levels at higher voltages while operating at lower logic levels. Consider the SO16 package constraints and thermal dissipation characteristics relative to the total power dissipation limits defined in the datasheet.

Shift Registers Part Context

This part belongs to the 74LV series, which is designed for low-voltage CMOS applications. The 74LV4094 specifically functions as an 8-stage shift-and-store bus register. It is distinct from the 74HCT or 74HC families by its optimized operation down to 1.0 V supply voltage and specific latch-up performance characteristics compliant with JEDEC standards.
