SN74LXC1T45QDRYRQ1

Translators, Level Shifters Overview

The SN74LXC1T45QDRYRQ1 is an automotive-grade, single-bit dual-supply bus transceiver with configurable level shifting. It operates with VCCA and VCCB supplies ranging from 1.1 V to 5.5 V. The device supports data rates up to 420 Mbps when translating between 3.3 V and 5.0 V. It features Schmitt-trigger inputs for noise immunity and integrated pull-down resistors on I/O and control pins. The component is housed in a 6-pin SON (DRY) package measuring 1.45 mm by 1.00 mm.

Translators, Level Shifters Feature Summary

• Fully configurable dual-rail design allowing independent voltage levels on each port
• Robust, glitch-free power supply sequencing ensures stable operation during power transitions
• Schmitt-trigger inputs provide noise filtering for slow or noisy signal environments
• Integrated dynamic pull-down resistors on I/O and static pull-downs on control inputs reduce external component requirements

Translators, Level Shifters Applications

• Driving indicator LEDs or buzzers with high drive strength
• Debouncing mechanical switches
• General-purpose I/O level shifting between different voltage domains

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix DRYRQ1 corresponds to the SON package and tape-and-reel quantity specified in the manufacturer's current orderable addendum. Confirm AEC-Q100 qualification status and temperature range compliance for your specific application environment before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when asynchronous communication requires translation between two independently powered logic domains. Ensure both supply rails remain within the 1.1 V to 5.5 V operating window. Consider the DIR pin reference to VCCA when designing control logic interfaces. Verify that the required data rate does not exceed the limits defined by the specific voltage translation direction.

Translators, Level Shifters Part Context

Translators, Level Shifters FAQ

How does the device handle partial-power-down scenarios?

The device supports partial-power-down mode via Ioff protection. If either supply is disconnected or below 100 mV, all I/Os are pulled down and enter a high-impedance state to prevent excessive current flow.

What is the reference voltage for the direction control input?

The direction-control input (DIR) is referenced to the VCCA logic level, determining the threshold for switching transmission direction between Port A and Port B.
