- Dual-supply architecture allows interfacing between different logic voltage domains, enabling safe 3.3V to 5V bus translation in mixed-voltage systems
- 48-pin SSOP package provides a compact high-density footprint suitable for space-constrained multilayer PCB designs in computing and communications hardware
- ALVC logic family offers low power consumption and high-speed switching for efficient bus buffering in battery-operated and power-sensitive applications
Applications
The 74ALVC164245DLR is designed for 16-bit bus bridging and voltage translation between 3.3V and 5V logic domains in microprocessor systems, memory bus interfaces, and FPGA I/O expansion circuits. It is widely used in data communication cards, server backplane interfaces, and industrial controller boards where large data width bus buffering and voltage-level isolation between subsystems are required. The device also serves as a robust bus isolator in test and measurement equipment where multiple boards share a common system bus with differing supply voltages.
