74FCT16245CTPVG8

Overview

The 74FCT16245CTPVG8 is a 16-bit bidirectional bus transceiver manufactured by Renesas Electronics. It integrates two independent 8-bit transceivers within a single package, facilitating asynchronous communication between data buses. The device operates with a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range from -40°C to +85°C. It utilizes a TSSOP-48 surface-mount package. The transceiver features three-state outputs and common control for direction selection.

Feature Summary

• Integrates two independent 8-bit bidirectional channels for efficient data routing
• Provides three-state outputs to prevent bus contention during inactive periods
• Supports asynchronous two-way communication via transmit/receive control input

Applications

• Asynchronous data bus communication systems
• Bidirectional data routing in computing architectures
• Memory interface buffering applications

Procurement Notes

Verify the specific suffix 'G8' against official Renesas documentation to confirm exact packaging and compliance status. Confirm RoHS3 compliance requirements. Check current production status as logic families may undergo lifecycle changes. Ensure pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component when designing systems requiring dual-channel 8-bit isolation or 16-bit wide data transfer. It is suitable for 5V logic environments needing high-speed bidirectional flow. Consider the TSSOP-48 footprint constraints. Evaluate propagation delay specifications against system timing requirements.
