Overview

Description

The SN74AXC1T45DBVR is a 1-bit, auto-directional voltage-level translator (bus transceiver) from TI’s AXC family. It translates a single data line between two supply domains, A-side (VCCA) and B-side (VCCB), with direction sensed automatically—no external DIR pin needed. It supports bidirectional data transfer between different logic levels, making it ideal for bridging I/O between microcontrollers, FPGAs, and peripherals across voltage domains. The device comes in a compact DBV (VSSOP-6) package and includes standard CMOS/TTL-compatible inputs with low static power. For exact voltage ranges, timing, and package details, consult the TI datasheet.

Features

Here are the key features of SN74AXC1T45DBVR:
- 1-bit bidirectional voltage-level translator between two supply rails (VCCA and VCCB)
- Independent VCCA and VCCB operation ranges
- DIR pin to select translation direction (A↔B)
- Small 6-pin DBV package
- Fast CMOS logic with low power consumption
- Wide operating temperature range (-40°C to 85°C)
- Reliable ESD protection on input/output pins
- Suitable for level shifting between different logic–level domains (e.g., 1.65–3.6 V family)
Note: For exact voltage ranges, current specifications, and timing, consult the datasheet.

Package

It uses an 8-pin VSSOP package (DBV). The trailing “R” denotes Tape-and-Reel packaging.

Pinout

- Pin count: 8 pins (VSSOP-8 package, DBVR).
- Function: One-bit, dual-supply, bidirectional level translator/buffer. It translates a single I/O between two voltage domains (A port on VCCA and B port on VCCB) with auto-direction sensing (no external direction pin required).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and embedded processing ICs, microcontrollers, DSPs, and other electronics components. It is one of the world’s largest semiconductor producers.

Application

SN74AXC1T45DBVR is a 1-bit, bidirectional, auto-direction-sensing voltage-level translator with two supply rails (VCCA and VCCB). Applications: translate a single bidirectional data line between different logic-voltage domains (e.g., 5V↔3.3V, 3.3V↔1.8/2.5V), interfacing MCUs/GPUs, FPGAs/PLDs, memories, and sensors, and enabling I/O expansion in mixed-voltage embedded systems. Suitable for low-to-mid-speed digital signals and cross-domain signal integrity in consumer, industrial, and automotive electronics.

Equivalent

Equivalent TI parts (same function, different families): SN74LVC1T45DBVR and SN74AUC1T45DBVR. They’re 1-bit, bidirectional level translators with auto-direction sensing like SN74AXC1T45DBVR, differing mainly by the voltage-translation family (LVC and AUC). If needed, packaging options include SN74LVC1T45IDBVR and SN74AUC1T45IDBVR.
