SN74BCT245PW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT245PW is an octal bus transceiver manufactured by Texas Instruments, belonging to the BCT logic series. It features eight bidirectional data channels with three-state outputs, allowing connection between two buses while isolating the source from the destination when disabled. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes TTL input levels. Packaged in a 20-pin TSSOP (PW) format, it supports propagation delays typical for BiCMOS technology.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transmission across eight independent channels
• Features three-state outputs to isolate the bus when disabled
• Compatible with TTL input logic levels for standard interface integration

Buffers, Drivers, Receivers, Transceivers Applications

• Memory buffer applications requiring high-speed data transfer
• Clock drivers for synchronous data systems
• Bus-oriented communications linking microprocessors and peripherals

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix 'PW' corresponds to the TSSOP-20 footprint required for your PCB layout. Confirm that the operating environment remains within the specified 4.5 V to 5.5 V power supply range to ensure signal integrity. Check current availability status as distribution may vary by region.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal bidirectional interface is needed with TTL-compatible inputs. Ensure the design accommodates the 20-pin TSSOP package dimensions. Verify that the system voltage strictly adheres to the 4.5 V minimum requirement to prevent malfunction.
