SN74LVCC3245ANS

Translators, Level Shifters Overview

The SN74LVCC3245ANS is an octal bus transceiver with adjustable output voltage and 3-state outputs. It features two separate supply rails: Port A operates at 2.3V to 3.6V, while Port B accepts voltages from 3V to 5.5V. The device provides robust, glitch-free power supply sequencing and includes VCC isolation and VCC disconnect features that disable I/O outputs when either supply falls below 100mV or remains floating. Control inputs are referenced to the VCCA voltage.

Translators, Level Shifters Procurement Notes

Verify the package suffix 'NS' corresponds to the specific SOIC variant required for your PCB footprint. Confirm that the manufacturing source matches your quality requirements, as Texas Instruments may utilize alternative fabrication sites. Ensure the component meets RoHS3 compliance standards if mandated by your project specifications.

Translators, Level Shifters Selection Notes

Select this component when interfacing asynchronous data buses requiring translation between 2.3V–3.6V and 3V–5.5V logic levels. It is suitable for designs needing high drive strength and protection against backflow current during power-down states. Ensure control inputs align with the VCCA reference voltage for proper direction and enable functionality.

Translators, Level Shifters Part Context

This part belongs to the SN74LVCC3245A family of octal bus transceivers. It shares core electrical characteristics with other variants in the series, differing primarily in packaging options such as SSOP, TSSOP, and narrow SOIC. The 'ANS' designation specifically identifies the standard SOIC package configuration within this product line.

Translators, Level Shifters FAQ

How does the device handle power sequencing?

The SN74LVCC3245A supports glitch-free power supply sequencing, allowing either supply rail to be powered on or off in any order without producing glitches on the I/Os.

What happens if one supply voltage drops below 100mV?

If either VCCA or VCCB input is below 100mV or left floating, all I/O outputs are disabled and enter a high-impedance state to prevent damaging current backflow.
