74FCT16245ETPAG

Overview

The Renesas 74FCT16245ETPAG is a dual 8-bit bidirectional bus transceiver belonging to the FCT logic family. It operates on a single 5V supply and features common control for direction and enable functions. The device utilizes a 48-pin TSSOP plastic package with a shrink pitch. It supports an operating temperature range from -40°C to +85°C. The component provides three-state outputs and includes power-off disable capabilities to permit live insertion without system interference.

Feature Summary

• Provides high-speed, low-power bidirectional data transfer between two buses
• Features power-off disable outputs to support safe live insertion operations
• Utilizes common control inputs for simultaneous direction and enable management

Applications

• Asynchronous two-way communication between data buses
• Memory bus architectures requiring bidirectional data flow
• High-density digital systems utilizing FCT logic families

Procurement Notes

Verify the specific suffix 'E' against official Renesas documentation to confirm tape-and-reel packaging and lead finish specifications. Confirm RoHS compliance status as it varies by manufacturing date code. Check for End-of-Life notices or obsolescence announcements prior to procurement to ensure long-term availability.

Selection Notes

Select this component when a dual 8-bit bidirectional interface is required within the FCT speed and power envelope. Ensure the design accommodates the 48-pin TSSOP footprint and thermal requirements. Verify that the 5V supply voltage aligns with the target system architecture and that common control signaling meets timing constraints.

Part Context

This part belongs to the 74FCT16245T series of fast CMOS bus transceivers. It serves as a standard interface solution for connecting microprocessors, memory devices, and peripheral controllers in industrial and commercial applications.
