Product details

Single-channel level translator with configurable gate logic

The TI SN74AUP1T57YFPR is a unidirectional voltage-level translator from the 74AUP series, in a 6-DSBGA package. It shifts logic levels between a VCCA supply of 1.8 V to 2.7 V and a VCCB supply of 2.3 V to 3.6 V, with configurable gate logic functions on a single channel.

Voltage translation — what the dual supply means for your design

The VCCA side accepts 1.8 V to 2.7 V, and VCCB accepts 2.3 V to 3.6 V. The unidirectional channel is for signals that flow one way only.

Package and mounting — 6-DSBGA footprint

The 6-DSBGA package is a fine-pitch BGA requiring solder-paste stencil and reflow. It is surface-mount only — no hand-solder rework.

Frequently asked questions

Is SN74AUP1T57YFPR compatible with 2.5V to 3.3V translation?

Yes. The VCCA range of 1.8 V to 2.7 V includes 2.5 V, and the VCCB range of 2.3 V to 3.6 V includes 3.3 V, so 2.5 V to 3.3 V translation is within spec.

What is the difference between SN74AUP1T57YFPR and SN74AUP1T57?

The suffix YFPR indicates the 6-DSBGA package and Tape & Reel. The base SN74AUP1T57 is the same die in a different package variant; check the package code for your board footprint.

What is the closest functional second-source for SN74AUP1T57YFPR?

The SN74LXC2T45DTTR is a bidirectional dual-channel level translator with a higher data rate (420 Mbps) and wider temperature range (-40 to 125°C), but it is not a pin-compatible drop-in. Verify your signal direction and package before substituting.
