SN74LVT245BRGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT245BRGYR is an octal bus transceiver manufactured by Texas Instruments, designed for asynchronous bidirectional data transmission. It operates within a supply voltage range of 2.7V to 3.6V and features three-state outputs. The device utilizes a 20-pin VQFN package with dimensions of 4.5mm length. It supports mixed-mode operation across ports and includes Ioff functionality to prevent back-driving when the device is powered down. The component is rated for an operating temperature range from -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transfer between two buses controlled by direction and output enable signals.
• Supports mixed-mode operation allowing different voltage levels on A and B ports.
• Includes Ioff feature to minimize current leakage during partial power-down states.

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous bidirectional data bus communication in embedded systems
• Voltage translation interfaces between 3.3V and 2.7V logic domains
• Memory and storage interface connections requiring tri-state isolation

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix BRGYR against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the procurement source provides documentation confirming RoHS compliance and lead-free status as specified in the component series standards. Cross-reference the part number with the latest Texas Instruments ordering information to validate availability and manufacturing status before finalizing orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low-voltage operation specifically within the 2.7V to 3.6V range. It is suitable for designs needing compact surface-mount packaging via the VQFN form factor. Consider its mixed-mode capabilities if interfacing between different voltage domains without external level shifters. Evaluate the propagation delay characteristics against system timing requirements to ensure signal integrity.
