SN74LV8T596BQBR

Shift Registers Overview

The SN74LV8T596BQBR is an 8-bit serial-in, parallel-out shift register with a storage register and open-drain outputs. It operates within a supply voltage range of 1.65V to 5.5V and features 5.5V tolerant inputs for level translation. The device includes Schmitt-trigger inputs on all signal lines. It utilizes a WQFN-16 package.

Shift Registers Feature Summary

• Integrated LVxT enhanced inputs combined with open-drain outputs provide maximum voltage translation flexibility
• Latching logic with known power-up state provides consistent start-up behavior
• All inputs include Schmitt-triggers to eliminate erroneous data outputs due to slow-edged or noisy input signals

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify that the ordering suffix BQB corresponds specifically to the WQFN-16 package configuration as defined in the manufacturer's documentation. Confirm that the component meets RoHS requirements and matches the exact part number SN74LV8T596BQBR before procurement to ensure correct pinout and thermal characteristics.

Shift Registers Selection Notes

Select this component when system design requires shifting serial data to parallel open-drain outputs with flexible voltage levels. It is suitable for applications needing up-translation from lower voltages or down-translation to 5.5V tolerant interfaces. Ensure external pull-up resistors are provided for the open-drain outputs to achieve high logic states.

Shift Registers Part Context

This device belongs to Texas Instruments' LVxT family of logic devices, which feature integrated voltage level translation capabilities. The SN74LV8T596 variant specifically combines an 8-bit shift register with a D-type storage register, designed to operate across a wide voltage range while maintaining compatibility with various CMOS logic families.

Shift Registers FAQ

How does the device handle unknown states during power-up?

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 behavior.

What is the function of the QH' pin?

QH' serves as a serial output that can be used for cascading multiple devices together. It is a push-pull output.
