概要

Description

The 74LVC1T45DW-7 is a single-channel, dual-supply level-shifting bidirectional buffer or translator from Texas Instruments. It is designed to facilitate communication between devices operating at different voltage levels, typically interfacing a 1.2V to 3.6V system with a 2.5V to 5.5V system. The device features a wide supply voltage range and supports high-speed data transmission with low propagation delay, making it suitable for applications in digital logic level translation.
The 74LVC1T45DW-7 operates with a low power consumption and is available in a compact SOT-23 package, allowing for efficient use in space-constrained designs. Its bidirectional capability ensures flexibility in interfacing, while its robust performance and compatibility with various logic families make it ideal for a range of applications, including microcontroller interfacing, sensor integration, and communication protocol conversion.

Features

The 74LVC1T45DW-7 is a single-bit dual supply voltage level shifter from the Texas Instruments LVC family. Key features include:
1. Voltage Level Shifting: Supports bidirectional level shifting between different voltage levels (from 1.2V to 5.5V).
2. Wide Supply Voltage Range: VCCA can range from 1.2V to 5.5V, and VCCB can range from 1.2V to 5.5V independently.
3. Low Power Consumption: Consumes minimal static and dynamic power, making it suitable for battery-operated devices.
4. High-Speed Operation: Capable of operating at speeds up to 30 Mbps.
5. TTL/CMOS Compatible: Compatible with TTL and other logic families, ensuring versatility in applications.
6. Single Gate Function: Provides a simple design with only one level-shifting gate needed for each signal.
7. Wide Operating Temperature: Designed for operation in the industrial temperature range (-40°C to +125°C).
This device is ideal for interfacing between different logic levels in mixed-voltage systems.

Package

The 74LVC1T45DW-7 is packaged in a SC70-5 (5-pin) type. This compact package is suitable for applications requiring low power consumption and space efficiency.

Pinout

The 74LVC1T45DW-7 is a single-bit dual-supply level-shifter from Texas Instruments. It features a total of 8 pins.
Pin Functions:
