Overview
The IDT 74LVCR162245AX4PF is a 16-bit bus transceiver featuring dual power supply domains and three-state outputs. It operates within a voltage range of 2.7V to 3.6V on Port A and up to 5.5V on Port B, enabling level shifting between different logic families. The device supports bidirectional data transfer controlled by direction and output enable signals, with inputs tolerant to 5V levels for compatibility in mixed-voltage systems.
Feature Summary
- Dual-supply architecture supporting independent voltage domains for Port A and Port B
- Bidirectional data transfer capability with direction control functionality
- Three-state outputs allowing effective bus isolation when disabled
- Input tolerance compatible with 5V logic systems for mixed-voltage interfacing
Applications
- Level translation between 3.3V and 5V logic domains
- Bidirectional data buffering in mixed-voltage system architectures
- Bus interface management in embedded controller designs
Procurement Notes
Verify the specific suffix 'X4P' against official IDT documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the LVCR series electrical characteristics rather than standard LVC variants. Confirm RoHS compliance status through the manufacturer's current datasheet before procurement.
Selection Notes
Select this component when designing interfaces requiring 16-bit wide data paths between 3.3V and 5V logic domains. The LVCR series offers higher drive strength compared to standard LVC devices. Verify that the required propagation delay and output current capabilities meet the system timing requirements for the target application bus speed.
Part Context
This part belongs to the IDT 74LVCR162245 family of 16-bit bus transceivers. The LVCR designation indicates enhanced performance characteristics suitable for high-speed applications. Similar parts include the SN74LVCR162245 from Texas Instruments, which shares functional similarities but may differ in specific electrical parameters and packaging options.
Replacement Considerations
The SN74LVCR162245DGGR from Texas Instruments serves as a functional equivalent. Verify pinout compatibility and ensure electrical parameters such as propagation delay and output current meet design requirements before substitution.
