74LVC8T595PWJ

Shift Registers Overview

The Nexperia 74LVC8T595PWJ is an 8-bit serial-in/serial-out or parallel-out shift register with a storage register and 3-state outputs. It features dual supply domains: VCC(A) for inputs (1.1 V to 5.5 V) and VCC(B) for outputs (1.1 V to 5.5 V). The device supports separate clocks for the shift and storage registers, includes an asynchronous master reset, and provides IOFF circuitry for partial power-down applications. It operates within a temperature range of -40 °C to +125 °C.

Shift Registers Feature Summary

• Dual supply voltage domains enable translation between various low-voltage nodes
• IOFF circuitry prevents damaging backflow current during partial power-down
• Separate clocks allow independent control of shift and storage registers
• Suspend mode isolates outputs when VCC(A) is at ground level

Shift Registers Applications

• Serial-to-parallel data conversion in mixed-voltage systems
• Remote control holding registers requiring voltage translation
• Partial power-down scenarios where output isolation is required

Shift Registers Procurement Notes

Verify the specific ordering suffix 'J' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure that the dual supply requirements align with your system's VCC(A) and VCC(B) voltage levels before procurement. Confirm RoHS compliance status through the manufacturer's latest environmental declaration.

Shift Registers Selection Notes

Select this component when designing circuits that require shifting data between different voltage domains without external translators. The dual-supply architecture simplifies interfacing between 1.1 V and 5.5 V logic families. Consider the TSSOP20 package constraints for PCB layout and thermal management in high-density designs.
