SN74LV8T594QPWRQ1

Shift Registers Overview

The SN74LV8T594QPWRQ1 is an automotive-grade octal shift register with output registers. It operates on a single supply voltage ranging from 1.65V to 5.5V and features 5.5V tolerant input pins. The device includes LVxT enhanced input voltage capabilities for up-translation and down-translation between various CMOS logic levels. It provides balanced CMOS push-pull outputs and supports data rates up to 150Mbps at 5V or 3.3V VCC.

Shift Registers Feature Summary

• AEC-Q100 qualified for automotive applications with specified temperature grades and ESD classification levels
• Latching logic circuitry with a known power-up state provided by an integrated Power On Reset (POR) circuit
• Integrated LVxT enhanced input voltage supporting both up-translation and down-translation across multiple voltage domains
• Balanced CMOS push-pull outputs designed to sink and source similar currents

Shift Registers Applications

• Digital signage systems
• Controlling indicator LEDs
• Increasing the number of outputs available on a microcontroller

Shift Registers Procurement Notes

Verify that the component meets AEC-Q100 qualification requirements for the intended automotive application environment. Confirm that the operating temperature range aligns with system specifications. Ensure proper handling procedures are followed due to electrostatic discharge sensitivity classifications. Validate that the package type matches the design footprint constraints.

Shift Registers Selection Notes

Select this component when serial-to-parallel conversion is required in automotive environments. Consider its capability to interface between different voltage domains using the LVxT feature. Evaluate the need for separate clocks for shift and storage registers to manage data loading independently. Assess the thermal performance requirements based on the TSSOP package configuration.
