74FCT162245ATPAG8

Overview

The IDT74FCT162245ATPAG8 is a dual 8-bit bus transceiver from the 74FCT logic family, housed in a 48-pin TSSOP package. It operates with a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. The device features balanced output drivers capable of sourcing and sinking 24 mA. Typical propagation delay is 3.5 ns at 50 pF load. Operating temperature ranges from -40 °C to +85 °C.

Feature Summary

• Dual 8-bit bidirectional data transfer capability
• Balanced output driver strength for reduced switching noise
• Power-off disable function enabling live insertion

Applications

• High-speed memory bus interfaces
• Buffering and driving bidirectional data buses
• System-level data routing applications

Procurement Notes

Verify the specific suffix 'A' against official Renesas or IDT documentation to confirm voltage and speed grades. Confirm RoHS compliance status via current datasheets as manufacturing sources may have changed following corporate acquisitions. Ensure pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component for designs requiring symmetric drive currents to minimize ground bounce. Verify that the 4.5 V minimum supply voltage aligns with system power rails. Consider the 3.5 ns delay for timing closure in high-frequency synchronous systems.

Part Context

This part belongs to the 74FCT series, designed for Fast CMOS performance with TTL-compatible inputs. It serves as a bridge between different logic families in mixed-voltage environments. The 48-pin TSSOP form factor allows for compact surface-mount assembly on dense circuit boards.
