SN74LV245ADBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV245ADBR is an octal bus transceiver manufactured by Texas Instruments, featuring three-state outputs. It operates within a supply voltage range of 2 V to 5.5 V and utilizes SSOP-20 packaging. The device supports bidirectional data transfer between two buses, controlled by direction (DIR) and output enable (OE) inputs. Key electrical characteristics include a maximum propagation delay of 6.5 ns at 5 V, high noise immunity, and support for mixed-mode operation on all ports.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Enables asynchronous bidirectional communication between data buses via configurable direction control.
• Supports mixed-mode voltage operation across all ports for interfacing different logic families.
• Includes Ioff feature to prevent reverse current flow when the device is partially powered down.

Buffers, Drivers, Receivers, Transceivers Applications

• Data bus interface applications in mixed-voltage systems
• Asynchronous bidirectional communication between memory and processors
• Bus-oriented architectures requiring isolation and direction control

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific revision level and package variant against the official Texas Instruments datasheet before procurement. Confirm that the SSOP-20 footprint matches your PCB design requirements. Ensure compatibility with your system's voltage levels and signal integrity needs. Check for any recent product lifecycle notices or recommended replacements from the manufacturer.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring wide voltage operation and low power consumption. Consider its propagation delay and drive capability relative to your bus speed requirements. Evaluate the need for three-state outputs and partial power-down protection features. Compare performance metrics against alternative bus transceivers if stricter timing or higher current drive is necessary.
