74FCT245ATPYG8

Buffers, Drivers, Receivers, Transceivers Overview

The Renesas Electronics Corporation 74FCT245ATPYG8 is an octal bus transceiver belonging to the FCT logic series. It features a single functional unit with eight bits per element and non-inverting true output polarity. The device utilizes CMOS technology and operates within a supply voltage range of 4.75V to 5.25V. It supports TTL input and output levels, ensuring compatibility with standard digital interfaces. The component is housed in a 20-pin SSOP package and is designed for surface mount installation. It functions as a bidirectional data buffer for asynchronous communication between buses.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides octal bidirectional data transmission capability for asynchronous two-way communication between data buses.
• Features direction control via a dedicated transmit/receive input to manage data flow through the transceiver.
• Supports high drive current outputs suitable for driving bus loads directly without additional buffering.

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous two-way communication between data buses
• Bus-oriented memory and command decoding applications
• High-speed data transfer systems requiring direction control

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact suffix 'PYG8' against official Renesas documentation to confirm pinout and electrical specifications, as variations exist within the FCT family. Ensure the source document explicitly lists this part number rather than a generic family member. Confirm RoHS compliance status and moisture sensitivity level requirements for your specific assembly process before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal, non-inverting bus transceiver with direction control is required for 5V logic systems. It is suitable for designs needing high-speed data transfer with TTL-compatible inputs and outputs. Consider the SSOP package constraints and operating temperature range (-40°C to +85°C) during PCB layout and thermal management planning.
