SN74LV595APWR

Shift Registers Overview

The SN74LV595APWR is an 8-bit serial input/serial or parallel output shift register with 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and features a working temperature range from -40°C to +125°C. The device is housed in a 16-TSSOP package (0.173 inch width) and supports surface mount installation. It includes a direct clear input for the shift register and separate clock inputs for the shift and storage registers.

Shift Registers Feature Summary

• Supports partial power-down mode operation to minimize current consumption during standby
• Latch performance exceeds 250mA, complying with JESD 78 Class II standards
• Inputs accept voltages higher than VCC up to 5.5V, facilitating interfacing with various logic families

Shift Registers Applications

• Embedded system output expansion
• LED matrix control systems
• Industrial equipment interface circuits
• Telecommunications signal processing

Shift Registers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and environmental compliance. Confirm that the RoHS status aligns with project requirements, as indicated by the REACH exemption and RoHS3 compliance data. Cross-reference the MSL rating to determine moisture sensitivity handling procedures during assembly.

Shift Registers Selection Notes

Select this component when a low-voltage CMOS shift register with wide operating voltage flexibility is required. The LV series offers lower power consumption compared to standard HC counterparts while maintaining compatibility with 5V systems. Ensure the design accommodates the separate clocking mechanism for shift and storage registers if precise timing control is necessary.

Shift Registers Part Context

This part belongs to the SN74LV595A family of 8-bit shift registers. It shares functional similarities with other members like the SN74LV595ARGYRG4 but differs in packaging, utilizing TSSOP-16 instead of VQFN-16. The 'PWR' suffix specifically denotes the plastic small-outline package variant with tape-and-reel shipping configuration.

Shift Registers Replacement Considerations

Direct substitutes include SN74LV595AIPWRG4Q1 for automotive-grade applications requiring AEC-Q100 qualification. For non-automotive equivalents, verify pinout compatibility with other SN74LV595 variants before substitution.
