54FCT245ATLB

Overview

The 54FCT245ATLB is an octal bidirectional transceiver manufactured by Renesas Electronics Corporation. It belongs to the FCT logic family and features a single function with eight bits of data width. The device utilizes a 20-pin DIP package and operates on a 5 V power supply. It supports a common control type for direction management and provides three-state outputs. The component is designed for asynchronous two-way communication between data buses, determining flow direction via the transmit/receive input.

Feature Summary

• Octal bidirectional data bus transceiver architecture
• Three-state output capability for bus isolation
• Common control direction management

Applications

• Asynchronous two-way communication between data buses
• General-purpose bus interface circuits

Procurement Notes

Verify the specific manufacturer source, as IDT was historically associated with this part number before acquisition by Renesas. Confirm RoHS compliance status, as some legacy listings indicate non-compliance. Ensure the package code matches the required 20-pin DIP form factor. Check for any discontinuance notifications or last-time buy orders from the supplier.

Selection Notes

Select this component when an octal wide bus interface is required for 5V CMOS systems. The FCT speed grade offers faster switching than standard LS logic. Verify that the 20-pin DIP package fits the target PCB layout. Ensure the operating temperature range meets the system requirements, typically -55°C to +125°C for military variants.

Part Context

This part is part of the 54FCT series, which denotes military-grade specifications compared to the commercial 74FCT series. It serves as a high-speed buffer and transceiver for parallel data transmission. The device is functionally similar to other octal transceivers but offers specific drive characteristics defined by the FCT technology node.
