Key Features
- 16-bit non-inverting bidirectional bus transceiver: enables full 16-bit parallel data transfer in both directions for high-throughput bus interfacing
- ALVTH logic family with 3.3 V / 5 V mixed-voltage tolerance: seamlessly bridges logic level mismatches between modern low-voltage and legacy 5 V TTL buses
- Dual 8-bit bus architecture: two independent 8-bit ports with separate output enable controls for flexible bus routing and multiplexing
- Compact 48-pin TSSOP package: supports high-density board layouts in processors, FPGAs, and DSP systems requiring wide bus transceivers
Applications
The 74ALVTH16245GR is used as a bidirectional bus buffer and level translator in processor systems, FPGAs, and memory interfaces where 16-bit parallel data buses operate across different logic voltage domains. Its ALVTH mixed-voltage tolerance makes it a key component for bridging 3.3 V and 5 V TTL logic systems in legacy equipment upgrades and new embedded computing designs. High-speed backplane data buses and address/data bus transceivers in industrial controllers and communications equipment rely on this device for reliable signal integrity.

Frequently Asked Questions
How many bits does the 74ALVTH16245GR bus transceiver support?
The 74ALVTH16245GR is a 16-bit transceiver organized as two independent 8-bit buses, supporting full 16-bit bidirectional parallel data transfer with separate output enable controls for each port.
What logic voltage levels does the 74ALVTH16245GR support?
It belongs to the ALVTH logic family, which supports 3.3 V operating supply with 5 V tolerant inputs, enabling use as a level translator between 3.3 V and 5 V TTL logic systems in mixed-voltage designs.
What package does the 74ALVTH16245GR come in?
The 74ALVTH16245GR is housed in a 48-pin TSSOP (Thin Shrink Small Outline Package), a fine-pitch SMD package providing a compact footprint for high-density PCB layouts in processor and FPGA interface boards.
Is the 74ALVTH16245GR inverting or non-inverting?
The 74ALVTH16245GR is non-inverting, meaning data passes through the transceiver without logic inversion, simplifying bus interface design and avoiding the need for software-level bit inversions in the connected system.
What applications is the 74ALVTH16245GR used in?
It is commonly used in processor address and data buses, FPGA I/O expansion, memory bus transceivers, and backplane interfaces where 16-bit bidirectional data transfer and mixed 3.3 V to 5 V voltage level translation are required.
