Overview
The 74FCT164245TPAG is a dual 8-bit bus transceiver manufactured by Renesas Electronics. It operates within the FCT logic family and supports bidirectional data transfer between two buses. The device features non-inverting outputs with three-state capability, allowing for effective bus isolation. It is designed to interface systems operating at different voltage levels, specifically bridging 3.3V and 5V domains. The component is housed in a 48-pin SSOP package suitable for surface-mount applications.
Feature Summary
- Supports bidirectional data transmission across two independent 8-bit channels
- Provides level shifting capabilities between 3.3V and 5V logic families
- Features three-state outputs to prevent bus contention during inactive states
Applications
- Interfacing 3.3V microprocessors with 5V peripheral devices
- Data routing in high-density memory architectures
- Bus isolation in mixed-voltage system designs
Procurement Notes
Verify the specific suffix 'TPAG' against official Renesas documentation to confirm pinout and packaging details. Confirm current production status as FCT series components may face obsolescence. Ensure compatibility with existing PCB footprint requirements for the 48-SSOP package before procurement.
Selection Notes
Select this component when interfacing mixed-voltage buses requiring high-speed data transfer. The FCT technology offers faster switching speeds compared to standard CMOS alternatives. Verify that the target application requires dual 8-bit channels and compatible input/output voltage thresholds for reliable operation.
Part Context
This part belongs to the 74FCT series of high-speed CMOS logic devices. It serves as a bridge between different logic families, enabling seamless communication in complex electronic systems. The device is part of Renesas's broader portfolio of interface solutions designed for industrial and consumer electronics.
Replacement Considerations
Check for direct substitutes such as IDT74FCT164245TPAG or equivalent parts from other manufacturers offering identical pinouts and electrical characteristics. Ensure any replacement maintains the same voltage level shifting specifications and package dimensions.
