Overview
The 74FCT164245TPAG8 is a 16-bit bidirectional bus transceiver manufactured by Renesas Electronics. It belongs to the 74FCT logic family and features eight channels of data transfer per direction, controlled by two independent circuits. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports three-state outputs. It utilizes a 48-pin SSOP package with a width of 7.50 mm. The component is designed for surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Provides bidirectional data transmission between two buses using sixteen bits of data paths
- Features three-state outputs that allow connection to multiple sources without interference
- Operates at standard 5V logic levels compatible with FCT-based systems
Applications
- Voltage level translation between different logic domains
- Bus switching and isolation in digital systems
- Data processing applications requiring high-speed signal routing
Procurement Notes
Verify the specific suffix 'TPAG8' against official Renesas documentation to confirm pinout and package dimensions. Ensure compatibility with existing PCB footprints before procurement. Check current production status as logic components may undergo lifecycle changes. Confirm RoHS compliance requirements match project specifications. Validate lead times with authorized distributors due to potential supply fluctuations.
Selection Notes
Select this component when a 16-bit bidirectional interface is required at 5V logic levels. The 74FCT series offers faster switching speeds compared to standard CMOS alternatives. Consider the 48-SSOP package constraints for board space limitations. Evaluate thermal performance within the specified industrial temperature range. Compare propagation delays against system timing requirements to ensure signal integrity.
Part Context
This part is part of the broader 74FCT164245 family of bus transceivers. It shares functional similarities with other 16-bit transceivers but differs in packaging and specific electrical characteristics. The TPAG8 designation indicates a specific tape and reel packaging configuration suitable for automated assembly processes. It serves as a critical interface element in complex digital architectures requiring reliable data transfer.
Replacement Considerations
Direct substitutes include SN74LVC16T245DL and SN74LVC16T245DLR from Texas Instruments. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Alternative packages such as TSSOP may require adapter solutions or layout modifications.
