SN74LV8T596QPWRQ1

Shift Registers Overview

The SN74LV8T596QPWRQ1 is an automotive-grade, 8-bit serial-in, parallel-out shift register with an integrated D-type storage register and open-drain outputs. It features LVxT enhanced inputs for logic-level translation between 1.2V and 5V domains. The device operates on a supply voltage range of 1.65V to 5.5V and supports data rates exceeding 6.67Mbps. It includes Schmitt-trigger inputs for noise immunity and latch-up protection exceeding 250mA per JESD 17.

Shift Registers Feature Summary

• Integrated LVxT enhanced inputs enable flexible voltage translation from 1.2V up to 5V or down from 5V to lower voltages.
• Open-drain CMOS outputs provide maximum voltage translation flexibility and require external pull-up resistors.
• Schmitt-trigger inputs eliminate erroneous data outputs caused by slow-edged or noisy input signals.
• AEC-Q100 qualified for automotive applications with specified temperature grades and ESD classification levels.

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific package variant (PW TSSOP or BQB WQFN) against the schematic footprint requirements. Confirm that the wettable flank feature is required if automatic optical inspection is part of the manufacturing process. Ensure the design accounts for the open-drain output configuration by including appropriate pull-up resistors in the circuit layout.

Shift Registers Selection Notes

Select this component when system architecture requires expanding I/O capabilities via serial interfaces while operating across mixed voltage domains. The LVxT technology allows direct interfacing between low-voltage controllers and higher-voltage peripherals without additional level-shifting components. Verify that the load capacitance and required data rates fall within the switching characteristics defined in the datasheet.

Shift Registers Part Context

This device belongs to Texas Instruments' SN74LV8T series of automotive-qualified logic devices. It combines shift register functionality with storage registers and level-shifting capabilities. The Q1 suffix indicates compliance with AEC-Q100 standards for automotive reliability. It serves as a bridge between digital control systems and peripheral loads requiring different voltage levels.
