74FCT162245CTPAG

Overview

The IDT74FCT162245CTPAG is a dual 8-bit bus transceiver from the 74FCT logic series, housed in a 48-pin TSSOP package. It features non-inverting true outputs and TTL-compatible input/output levels. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended commercial temperature range from -40 °C to +85 °C. Electrical characteristics include a maximum propagation delay of 3.5 ns at a 50 pF load, with output drive capabilities of ±24 mA.

Feature Summary

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

Applications

• High-speed memory bus interfaces
• Buffering and direction control in digital systems
• Data acquisition systems requiring balanced drive

Procurement Notes

Verify the complete part number against manufacturer documentation to ensure correct suffix alignment. Confirm that the TSSOP-48 package variant matches specific board layout requirements. Check for RoHS compliance status as indicated by the 'A' suffix in official datasheets. Ensure sourcing channels provide original manufacturer packaging to prevent counterfeit components.

Selection Notes

Select this component when balanced current drive is required to minimize ground bounce and switching noise. Compare against high-drive variants like the 74FCT16245 if asymmetric output currents are acceptable. Verify that the 3.5 ns propagation delay meets timing constraints for the target bus speed. Ensure the 48-pin TSSOP footprint fits the available PCB space.

Part Context

This device belongs to the IDT 74FCT family, designed as a high-speed, low-power CMOS replacement for older ABT functions. It utilizes 0.5 micron CMOS technology to offer improved performance over standard FCT devices while maintaining compatibility with existing designs.

Replacement Considerations

Cross-reference with CY74FCT162245TPVC or PI74FCT162245T for potential pin-compatible alternatives from other manufacturers.
