SN74LV595BMPWREP

Shift Registers Overview

The SN74LV595B-EP is an enhanced product 8-bit serial-in, parallel-out shift register with a storage register and 3-state outputs. It operates on a supply voltage of 2 V to 5.5 V and supports mixed-mode voltage operation across all ports. The device features separate clocks for the shift and storage registers, a direct overriding clear input, and a serial output for cascading. It includes Ioff circuitry to support partial-power-down mode by disabling outputs and preventing backflow current. The component is designed for extended product life cycles and traceability.

Shift Registers Feature Summary

• Enhanced product specifications supporting defense, aerospace, and medical applications with controlled baseline and single assembly/test/fabrication sites.
• Integrated Ioff circuitry enables partial-power-down mode operation by disabling outputs when powered down.
• Balanced CMOS 3-state outputs allow for high-impedance states while maintaining similar sourcing and sinking capabilities.
• Robust latch-up performance exceeding specified limits per industry standards.

Shift Registers Applications

• Output expansion in embedded systems
• LED matrix control
• 7-segment display control

Shift Registers Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape/reel configuration. Confirm that the Enhanced Product (EP) designation aligns with project requirements for controlled baselines and extended lifecycle support. Ensure compatibility with system voltage levels and thermal management constraints before finalizing procurement.

Shift Registers Selection Notes

Select this component when mixed-mode voltage operation and partial-power-down capabilities are required. The balanced 3-state outputs make it suitable for driving displays or LEDs where high-impedance states are necessary. Consider the operating temperature range and ESD ratings for harsh environments. Verify that the serial interface requirements match the available GPIO pins on the host controller.
