74LVC245AQ20-13

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.

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

Applications

• General purpose logic
• Bus driving
• Power down signal isolation
• Networking computer peripherals
• TV, DVD, DVR, Set Top Box

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.

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.

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.
