概述

Description

SN74AXCH1T45DCKR is TI’s 1-bit, bidirectional voltage-level translator with auto-direction sensing. It translates a single data line between two supply rails (VCCA on the A side and VCCB on the B side) without a direction pin. The device automatically detects the direction of data flow, enabling safe interfacing between devices operating at different logic voltages (for example, 1.8 V and 3.3 V). It’s used to connect microcontrollers, FPGAs, memories, or other peripherals across voltage domains. The DCKR suffix indicates an 8-pin package (typically VSSOP) in tape-and-reel packaging. Key benefits include simplicity (no extra control signals), fast operation, and low leakage. For exact voltage ranges, timing, and current specs, consult the TI datasheet. If you’d like, I can pull out the critical figures you need.

Package

DCKR indicates the DCK package, i.e., an 8-pin VSSOP (Very Small Outline Package) with Tape & Reel.

Pinout

- Pin count: 8 pins (8-pin package, DCKR variant).
- Function: 1-bit bidirectional voltage-level translator between two supply domains (A side and B side), translating a single data line between VCCA and VCCB.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and digital integrated circuits and related electronics. It is one of the world’s largest semiconductor producers, headquartered in Dallas, Texas.

Equivalent

Equivalent parts (1-bit bidirectional level shifters with auto-direction):
- TI SN74LVC1T45
- Nexperia 74LVC1T45
