Description

The 74AVCH1T45GW is a high-speed, single-bit, dual-supply level-shifter from Texas Instruments. It is designed to facilitate communication between devices operating at different voltage levels, typically between 1.2V and 3.6V. This device features a bidirectional design, allowing signals to be transferred seamlessly in both directions.
Key features include:
- Dual Supply Operation: It can interface with two different voltage levels, making it ideal for mixed-voltage applications.
- High-Speed Performance: The device supports fast switching speeds, which is crucial for high-frequency applications.
- Low Power Consumption: With a low quiescent current, it is suitable for battery-powered devices.
- Application Versatility: Commonly used in scenarios such as I2C, SPI, and UART communications.
Its compact size and versatility make the 74AVCH1T45GW a popular choice in modern digital designs, particularly in mobile and embedded systems.

Features

The 74AVCH1T45GW is a single two-way voltage-level translator that facilitates bidirectional communication between devices operating at different voltage levels, typically between 1.2V and 3.6V. Key features include:
1. High-Speed Operation: Supports data rates up to 30 Mbps, making it suitable for high-speed applications.
2. Low Power Consumption: Designed for low power usage, ideal for battery-operated devices.
3. Wide Voltage Range: Compatible with a variety of logic levels, enhancing versatility in mixed-voltage environments.
4. Active-Low Enable Input: Allows easy control of the device operation.
5. Compact Packaging: Available in a small form factor (e.g., TSSOP or similar), suitable for space-constrained designs.
6. ESD Protection: Offers protection against electrostatic discharge, ensuring reliability in various conditions.
This device is commonly used in mobile devices, microcontroller interfacing, and other applications requiring seamless voltage level adaptation.

Package

The 74AVCH1T45GW is packaged in a SOT-23 (Small Outline Transistor-23) package type.

Pinout

The 74AVCH1T45GW is a single-bit dual supply level shifter. It features a total of 8 pins. The pin configuration is as follows:
1. A: Input from the low voltage side (LV).
2. B: Output to the high voltage side (HV).
3. GND: Ground connection.
4. VCCA: Supply voltage for the low voltage side (typically 1.2V to 3.6V).
5. VCCB: Supply voltage for the high voltage side (typically 1.65V to 5.5V).
6. DIR: Direction control input that determines the data flow direction (A to B or B to A).
7. nC: Active-low enable control (not all variants may have this).
8. nC: No connect (not used, can be left floating).
The device allows bidirectional voltage level translation, making it suitable for interfacing between different voltage domains in digital circuits.
