74LVC245AQ20-13

Buffers, Drivers, Receivers, Transceivers Overview

The Diodes Incorporated 74LVC245AQ20-13 is an octal bus transceiver with three-state outputs, designed for asynchronous communication between data buses. It operates within a supply voltage range of 1.65V to 3.6V and features inputs tolerant to 5.5V for mixed-voltage environments. The device supports partial power-down applications via I_OFF circuitry. It is housed in a V-QFN4525-20 package (Q20) and supplied in 13-inch tape and reel quantities.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports bidirectional data transmission between A and B buses controlled by the DIR input
• Provides isolation capability through the OE pin to disable outputs
• Includes I_OFF circuitry to prevent damaging current backflow during partial power-down
• Features Schmitt trigger action at all inputs for noise immunity

• Power down signal isolation
• Networking computer peripherals
• TV, DVD, DVR, Set Top Box

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the Q20 suffix corresponds to the V-QFN4525-20 package type rather than TSSOP-20. Confirm the -13 packing suffix indicates 13-inch tape and reel packaging. Ensure the component meets RoHS compliance and halogen-free requirements as specified in the manufacturer documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with three-state outputs is required for mixed-voltage systems. The 5.5V input tolerance allows compatibility with 3.3V or 5V driven signals. The V-QFN4525-20 package offers a compact footprint suitable for space-constrained designs requiring surface mount technology.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74LVC245A series of octal bus transceivers manufactured by Diodes Incorporated. The 'Q20' designation specifically identifies the V-QFN4525-20 package variant, distinguishing it from the TSSOP-20 version. The '-13' suffix denotes the standard 13-inch tape and reel packaging format used for automated assembly processes.
