Description

The SN74LVC16T245DLR is a 16-bit bus transceiver from Texas Instruments, designed for asynchronous communication between data buses. It features dual supply voltage levels, allowing it to perform level translation between 1.65V to 5.5V on A-port and 1.65V to 5.5V on B-port, making it versatile for interfacing different logic levels. The device operates with a direction-control capability, which determines the data flow direction through the transceiver.
Key features include over-voltage tolerant inputs, support for partial power-down applications through the Ioff circuitry, and high drive output capability. It also has a low power consumption design, making it suitable for battery-powered applications. The SN74LVC16T245DLR is commonly used in applications requiring bidirectional data flow and level shifting in consumer electronics, computing, and industrial environments. The device is packaged in a small outline, making it suitable for space-constrained applications. It supports a broad temperature range, enhancing its reliability across various operating conditions.

Features

The SN74LVC16T245DLR is a 16-bit bus transceiver with configurable voltage translation and direction control, designed for high-performance applications. Key features include:
1. Voltage Level Translation: Supports bidirectional voltage translation between 1.65 V to 5.5 V on A-port and 1.65 V to 5.5 V on B-port.
2. High-Speed Operation: Offers fast data transfer rates and supports high-speed digital applications.
3. Low Power Consumption: Incorporates LVC technology for reduced power usage, making it suitable for battery-powered and energy-efficient systems.
4. 3-State Outputs: Outputs can be placed in a high-impedance state, allowing for bus sharing and preventing conflicts.
5. Drive Capability: Provides strong drive capability with balanced propagation delay, suitable for driving multiple loads.
6. Direction Control: DIR pin controls the direction of data flow, allowing for easy management of data paths.
7. Overvoltage Tolerance: Inputs are tolerant to voltages higher than the supply voltage, adding protection and flexibility.
8. Compact Package: Available in small-outline and leadless packages for space-constrained applications.
This device is ideal for applications requiring reliable, high-speed level shifting between different voltage domains.

Package

The SN74LVC16T245DLR is a dual-supply bus transceiver with configurable voltage translation and dual-enable, designed for 1.65-V to 5.5-V VCC operation. Its package type is a 48-pin thin shrink small-outline package (TSSOP).

Pinout

The SN74LVC16T245DLR is a 16-bit bus transceiver from Texas Instruments. It is designed for asynchronous communication between data buses and can handle mixed-voltage systems. The device has 48 pins and is packaged in a surface-mount style.
