74FCT16245CTPVG8

Overview

The IDT 74FCT16245CTPVG8 is a high-speed, low-power CMOS bus transceiver belonging to the FCT logic series. It features two independent bidirectional data paths, each providing 8 bits of transfer capability for a total of 16 channels. The device utilizes 0.5-micron CMOS technology and operates within an extended commercial temperature range from -40°C to +85°C. It is housed in a 48-pin Thin Shrink Small Outline Package (TSSOP) with a 0.65mm pitch. Key electrical characteristics include high drive outputs capable of sourcing -32mA and sinking 64mA, ensuring robust signal integrity across system buses.

Feature Summary

• Provides dual 8-bit bidirectional data transfer paths for efficient 16-bit bus interfacing
• Features high-current output drivers designed for reliable signal transmission
• Incorporates power-off disable functionality to support live insertion applications
• Utilizes advanced 0.5-micron CMOS technology for high speed and low power consumption

Applications

• High-speed memory bus architectures requiring bidirectional data flow
• System control signal routing in complex electronic designs
• Data acquisition systems utilizing live insertion capabilities
• General-purpose 16-bit data bus interfaces in industrial equipment

Procurement Notes

Verify the specific suffix 'G8' against official Renesas or IDT documentation, as this variant may indicate specific tape-and-reel packaging or environmental compliance distinct from standard bulk versions. Confirm RoHS status and lead-free composition requirements prior to procurement. Ensure compatibility with existing PCB footprints for the 48-pin TSSOP package. Check for end-of-life notices or obsolescence warnings associated with this specific part number revision.

Selection Notes

Select this component when designing systems requiring 16-bit bidirectional data transfer with high drive strength. It serves as a suitable replacement for older ABT family devices where lower power consumption is required. Consider the -40°C to +85°C operating range for industrial environments. Evaluate the need for power-off disable features if hot-swapping capabilities are necessary for the target application architecture.

Part Context

This device belongs to the IDT 74FCT16245T family of fast CMOS bus transceivers. The family includes variants such as the AT, CT, and ET grades, which differ primarily in propagation delay specifications and drive current capabilities. The 74FCT series is engineered to replace faster but more power-hungry ABT logic families while maintaining pin compatibility and functional equivalence for many legacy designs.

Replacement Considerations

Direct substitutes within the same family include the 74FCT16245AT and 74FCT16245ET, depending on required speed and drive current specifications. Cross-manufacturer equivalents from Renesas or Diodes Incorporated should be verified for pinout compatibility and electrical parameter alignment.
