Overview
The IDT 74ALVC164245PAG8 is a 16-bit dual-supply translating transceiver manufactured by Integrated Device Technology. It features two independent power rails, VCCA and VCCB, allowing operation in mixed-voltage environments such as 3.3V to 5V systems. The device provides non-inverting three-state outputs for bidirectional data transfer between buses with different voltage levels. It supports asynchronous communication and includes direction control (DIR) and output enable (OE) inputs referenced to their respective supply voltages.
Feature Summary
- Dual-supply architecture enabling translation between distinct voltage domains
- Bidirectional data transfer capability with non-inverting logic
- Three-state outputs for bus isolation and multi-driver compatibility
- Asynchronous interface design for flexible system integration
Applications
- Mixed-voltage bus interfacing in embedded systems
- Data translation between 3.3V and 5V logic domains
- Peripheral device connectivity in industrial control systems
Procurement Notes
Verify the specific suffix 'PAG8' against official Renesas or IDT documentation, as standard listings often use 'PAG'. Confirm package type is TSSOP-48 and check for moisture sensitivity level requirements during storage and handling. Ensure the manufacturer source aligns with current corporate ownership structures.
Selection Notes
Select this component when bridging asynchronous buses operating at different voltage levels. It is suitable for applications requiring high-speed data transfer with low power consumption. Consider the propagation delay and drive strength specifications relative to the target bus speed and load capacitance requirements.
Part Context
This part belongs to the 74ALVC family of high-performance CMOS logic devices. It is functionally similar to other 16-bit translators like the SN74ALVC164245 from Texas Instruments. The device is designed to replace older TTL-compatible logic in modern low-voltage digital designs.
Replacement Considerations
Direct substitutes include the SN74ALVC164245DGGR from Texas Instruments. Verify pinout compatibility and electrical characteristics before swapping.
