74FCT162245CTPAG

Overview

The Renesas Electronics Corporation 74FCT162245CTPAG is a dual bus transceiver belonging to the 74FCT logic series. It integrates two independent 8-bit bidirectional channels within a single 48-pin TSSOP package. The device operates with a supply voltage range of 4.5V to 5.5V and supports TTL input and output levels. Key electrical specifications include maximum high-level output current of -24mA and low-level output current of 24mA. The propagation delay is specified at 3.5ns under a 50pF load condition. The component functions across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing two independent 8-bit bidirectional data paths
• High-current drive capability with balanced ±24mA output drivers
• TTL-compatible input and output logic levels for system integration
• Power-off disable feature enabling safe live insertion operations

Applications

• High-speed memory interface circuits
• Buffering and driving in complex digital systems
• Bidirectional data bus architectures requiring isolation

Procurement Notes

Verify the specific manufacturer designation, as IDT was acquired by Renesas. Confirm the exact suffix 'CTPAG' matches the required RoHS compliance and tape-and-reel packaging format. Ensure the datasheet version aligns with current technical specifications before finalizing procurement orders.

Selection Notes

Select this component when a dual 8-bit bidirectional transceiver is required with high drive strength. It serves as a direct replacement for legacy IDT variants. Consider the 48-pin TSSOP footprint constraints and verify that the 4.5V to 5.5V operating voltage aligns with the target system power rails.

Part Context

This part belongs to the 74FCT family of Fast CMOS logic devices. It is functionally equivalent to the IDT74FCT162245CTPAG prior to corporate acquisitions. The device provides non-inverting transmission characteristics suitable for general-purpose bidirectional data transfer applications in industrial and commercial electronics.

Replacement Considerations

The Texas Instruments 74FCT162H245ATPACT is listed as a discontinued alternative. Verify pinout compatibility and electrical parameter alignment when substituting with other manufacturers' FCT-series dual bus transceivers.
