The 74ALVT16827DGG from NXP is a 2-channel non-inverting buffer from the 74ALVT logic family. It supports dual supply ranges of 2.3V-2.7V and 3V-3.6V, making it ideal for 2.5V and 3.3V systems. The device provides 3-State outputs with 32mA source and 64mA sink drive. Its BiCMOS technology delivers high speed with low power consumption. The 56-pin TFSOP package is compact for high-density boards. Typical applications include memory buffering, telecom switching, and networking backplanes.
- Dual Voltage Ranges (2.3V-3.6V): Supports both 2.5V and 3.3V logic, reducing part count in mixed-voltage designs.
- High Drive Current (64mA Sink): Drives heavy bus loads with excellent signal integrity.
- Fast Propagation Delay (2.5ns typical): Suitable for high-frequency applications.
- 3-State Outputs: Enables bus sharing and hot-swap capability.
- BiCMOS Technology: Balances speed and power efficiency.
Dual-Voltage Bus Interfacing
Use the 74ALVT16827DGG to interface between 2.5V and 3.3V logic domains. Its dual voltage ranges (2.3V-2.7V and 3V-3.6V) allow seamless bridging without external level shifters.
High-Speed Server Memory Buffers
In server memory subsystems, this buffer drives address and control lines between the memory controller and DIMMs. The 64mA sink capability handles the high capacitance of multiple memory modules.
Telecommunications Switching Fabric
For high-speed telecom switches, this device buffers parallel data paths between line cards and the switch core. The BiCMOS technology provides fast propagation delays (typical 2.5ns) essential for high-throughput systems.
Networking Equipment Backplanes
In routers and switches, this buffer drives signals across the backplane to multiple line cards. The 3-State outputs prevent bus contention during hot-swap operations.
FPGA Configuration Interfacing
When configuring FPGAs from a 2.5V or 3.3V configuration device, this buffer conditions the serial/parallel data lines. Its wide voltage tolerance ensures compatibility with various FPGA families.
Industrial Control Processors
For industrial PCs with 2.5V core logic and 3.3V I/O, this buffer provides the necessary level translation and drive strength for control signals to motors and actuators.
