SN74LV8T596PWR

Shift Registers Overview

The SN74LV8T596PWR is an 8-bit serial-load shift register with open-drain outputs and logic-level shifting capabilities. It operates within a supply voltage range of 1.65V to 5.5V, featuring 5.5V tolerant inputs for down-translation and reduced threshold circuits for up-translation. The device includes Schmitt-trigger inputs to eliminate erroneous data from slow-edged signals. It provides separate clocks for the shift and storage registers, along with a direct overriding clear input. The component is housed in a 16-pin TSSOP package.

Shift Registers Feature Summary

• Integrated power-on reset circuitry ensures consistent start-up behavior by setting known latch states during power-up.
• LVxT enhanced inputs combined with open-drain outputs provide maximum voltage translation flexibility for mixed-voltage systems.
• Schmitt-trigger inputs eliminate erroneous data outputs caused by slow-edged or noisy input signals.

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify that the ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm RoHS compliance status through official documentation. Ensure the specific variant meets the thermal requirements for the intended operating environment. Cross-reference the datasheet revision history for any functional updates before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when designing systems requiring serial-to-parallel conversion with level-shifting capabilities. It is suitable for applications needing to expand I/O lines while managing different voltage domains. Consider the open-drain output requirement for external pull-up resistors. Verify that the operating temperature range aligns with the environmental conditions of the target application.

Shift Registers Part Context

This device belongs to Texas Instruments' LVxT family of logic devices, which are designed for low-voltage operation with enhanced input/output characteristics. The SN74LV8T596 specifically integrates voltage translation features, allowing it to interface between components operating at different supply voltages without additional level-shifting hardware.

Shift Registers Replacement Considerations

Consult the official datasheet for confirmed substitute part numbers. Verify pin compatibility and electrical specifications before substitution.

Shift Registers FAQ

How does the device handle unknown states after power is applied?

The device includes a Power On Reset (POR) circuit that sets the states of all latching circuits during the power-up ramp, ensuring a known start-up state.

What is the function of the QH' pin?

QH' serves as a serial output that can be used for cascading multiple devices together.
