Overview
The 74ALVC164245XE4PA is a 16-bit bidirectional level-shifting transceiver manufactured by IDT using advanced dual metal CMOS technology. It facilitates data transfer between 3.3V and 5V logic domains. The device features three-state outputs and operates within a supply voltage range of 3.0V to 3.6V. Key electrical parameters include a propagation delay of 4.2ns and a quiescent current of 100nA. It supports operation temperatures from -40°C to +85°C and is housed in a TSSOP-48 package.
Feature Summary
- Provides bidirectional level shifting between 3.3V and 5V logic systems
- Utilizes advanced dual metal CMOS technology for high-speed performance
- Features three-state outputs for bus line management
Applications
- FPGA high-speed data handling interfaces
- Control system signal translation
- Bidirectional bus architecture interconnects
Procurement Notes
Verify the specific suffix 'XE4PA' against official IDT documentation to confirm RoHS compliance and lead-free status, as these attributes are tied to the ordering code. Ensure the source document explicitly identifies Integrated Device Technology Inc as the manufacturer. Cross-reference the TSSOP-48 package type and 16-channel configuration with the datasheet to avoid confusion with similar ALVC series variants.
Selection Notes
Select this component when interfacing 3.3V and 5V logic families requiring 16-bit parallel data transfer. The ALVC series offers superior speed compared to standard LVC devices. Confirm that the application environment stays within the specified -40°C to +85°C temperature range. Verify that the 3.0V to 3.6V VCC operating range matches the target system power supply constraints.
Part Context
This part belongs to the 74ALVC (Advanced Low-Voltage CMOS) family, designed for high-speed digital applications. The 164245 designation indicates a 16-bit bidirectional transceiver with auto-direction control. IDT, now part of Renesas Electronics, produces this series for robust signal integrity in mixed-voltage environments.
Replacement Considerations
The 74ALVC164245PAG is a documented equivalent from Renesas Electronics. Verify pinout compatibility and electrical specifications before substitution.
