54FCT245ATDB

Overview

The 54FCT245ATDB is an octal bidirectional transceiver manufactured by Renesas Electronics. It utilizes FCT CMOS logic technology and operates within a supply voltage range of 4.5 V to 5.5 V. The device features a propagation delay of 6.8 ns at nominal supply. It provides a low-level output current of 48 mA and a high-level output current of -15 mA. The component supports an operating temperature range from -55 °C to +125 °C and is housed in a CDIP-20 package.

Feature Summary

• Octal bidirectional data transfer capability for asynchronous communication between buses
• High drive strength with 48 mA low-level output current
• Industrial temperature range support up to +125 °C

Applications

• Asynchronous two-way communication between data buses
• Industrial control systems requiring wide temperature tolerance
• Military-grade electronic equipment applications

Procurement Notes

Verify the specific suffix 'ATDB' against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status as sources indicate non-compliance. Check for active production status or obsolescence notices before procurement planning.

Selection Notes

Select this component when an octal bus transceiver with industrial temperature range and high drive current is required. Ensure the system operates within the 4.5 V to 5.5 V supply voltage limits. Verify that the CDIP-20 package form factor fits the target PCB layout constraints.

Part Context

This part belongs to the 54FCT series, which denotes military-grade performance levels using Fast CMOS technology. It serves as a buffer and direction controller for eight-bit data paths.
