74LV165DB,118

Shift Registers Overview

The Nexperia 74LV165DB,118 is an 8-bit parallel-in/serial-out shift register housed in a 16-lead SO16 (SOT109-1) plastic small outline package. It operates within a supply voltage range of 1.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features eight parallel data inputs (D0–D7), a serial data input (DS), and complementary serial outputs (Q7 and Q7). Asynchronous parallel loading occurs when the PL input is LOW, while serial shifting is controlled by the clock enable (CE) and clock pulse (CP) inputs.

Shift Registers Feature Summary

• Supports wide supply voltage operation from 1.0 V to 5.5 V
• Provides direct interface capability with TTL logic levels
• Includes clamp diodes on inputs for overvoltage tolerance
• Offers high latch-up performance exceeding 100 mA

Shift Registers Applications

• Synchronous parallel-to-serial data conversion
• Synchronous serial input expansion systems
• Low voltage digital logic interfacing

Shift Registers Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the 74LV165 family includes distinct variants such as TSSOP packages. Confirm the component status against current Nexperia documentation to ensure availability, as product lifecycles may change. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and sourcing channels before procurement.

Shift Registers Selection Notes

Select this component for applications requiring low-voltage CMOS operation with broad supply compatibility. Ensure the design accommodates the specified temperature range and power dissipation limits. Verify that the system logic levels align with the device's direct TTL interface capabilities. Consider the package dimensions and thermal characteristics during PCB layout planning.

Shift Registers Part Context

This component belongs to the 74LV165 family of 8-bit shift registers manufactured by Nexperia. The family provides parallel-in/serial-out functionality optimized for low-voltage applications. Variants within the family differ primarily in packaging options, such as SO16 or TSSOP16, while maintaining identical logical operations and electrical specifications across the series.

Shift Registers Replacement Considerations

The 74LV165PW,118 serves as a functional substitute utilizing a TSSOP16 package instead of the SO16 form factor.
