74FCT16245ATPVG8

Overview

The IDT74FCT16245ATPVG8 is a 16-bit bus transceiver from the 74FCT series, manufactured by Integrated Device Technology. It features two independent 8-bit transceivers with true outputs and three-state capabilities. The device operates within a supply voltage range of 2.7V to 3.6V for VCCA and 4.5V to 5.5V for VCCB, enabling level shifting between different logic families. It utilizes 0.5-micron CMOS technology to provide high-speed performance with low power consumption. The component is housed in a 48-pin Thin Shrink Small Outline Package (TSSOP) suitable for surface mount applications.

Feature Summary

• Provides bidirectional data transmission across two independent 8-bit channels
• Supports voltage level translation between 3.3V and 5V logic domains
• Features three-state outputs to prevent bus contention during inactive states
• Offers high drive capability with strong output current sourcing and sinking

Applications

• High-speed data buses requiring 3.3V to 5V level translation
• Memory interface circuits connecting different voltage logic families
• Control signal routing in mixed-voltage embedded systems
• Data acquisition systems interfacing analog-to-digital converters

Procurement Notes

Verify the specific suffix 'TPVG8' against official Renesas or IDT documentation to confirm package type, tape-and-reel specifications, and environmental compliance status. Ensure the selected variant matches the required operating temperature range and pinout configuration for your PCB layout. Cross-reference the manufacturer's latest datasheet to confirm availability and any potential design changes.

Selection Notes

Select this component when designing systems that require robust level shifting between 3.3V and 5V logic levels with high drive strength. Consider the TSSOP-48 package constraints regarding thermal dissipation and board space. Evaluate the propagation delay characteristics against your system's timing requirements to ensure signal integrity is maintained across the bus.

Part Context

This part belongs to the widely adopted 74FCT logic family, known for replacing older ABT functions with faster, lower-power CMOS alternatives. The 74FCT16245 variant specifically addresses the need for dual 8-bit bidirectional transfer in mixed-voltage environments. IDT, now part of Renesas Electronics, continues to support this legacy line for industrial and commercial applications requiring reliable level-shifting capabilities.

Replacement Considerations

Check for direct substitutes such as the SN74LVC16T245DL from Texas Instruments, which offers similar functionality but may differ in electrical characteristics and package dimensions. Verify compatibility with existing PCB footprints and ensure that the replacement meets the same voltage and speed requirements.
