DESCRIPTION

Description

OVERVIEW

Product Overview

The SN74AVC1T45DCKR is a single-bit dual-supply level translator from Texas Instruments in an SC-70-6 package, used to interface logic circuits that operate at different supply voltages. It has two independent supply pins and performs bidirectional signal translation between two voltage domains, with direction set by a direction-control pin. It is commonly used for level matching between processors, peripherals, and interfaces in mixed-voltage systems, helping prevent logic errors caused by voltage mismatch. Voltage ranges, translation rates, and drive capability should be confirmed from the original datasheet.

APPLICATIONS

Applications

  • Signal level matching between processors and peripherals in mixed-voltage systems.
  • Connecting low-speed digital interfaces across different voltage domains.
  • Signal translation between internal logic blocks in portable devices.
FEATURES AND BENEFITS

Features and Benefits

  • Dual-supply design supports translation between different voltage domains.
  • Direction control allows bidirectional signal transfer.
  • Single-channel structure suits point-to-point level matching.
  • SC-70-6 package occupies minimal board area.
ADDITIONAL DETAILS

Additional Details

When ordering, verify the package, supply voltage range, and direction-control pin definitions against the recommended operating conditions in the original datasheet.

Verify product details against the manufacturer datasheet before purchase.
