The 74ALVCH16825DLR is a high-performance dual non-inverting buffer from Texas Instruments, part of the advanced 74ALVCH logic family. Engineered for low-voltage operation from 1.65V to 3.6V, it provides robust signal buffering with 24mA output drive capability. Its 3-State outputs enable efficient bus multiplexing, making it ideal for memory interfaces, high-speed data paths, and mixed-voltage systems. The 56-BSSOP package offers a compact solution for space-constrained designs.
- Wide 1.65V to 3.6V Supply Range: Compatible with 1.8V, 2.5V, and 3.3V logic levels, simplifying mixed-voltage design.
- High 24mA Output Drive: Ensures strong signal integrity and supports high fan-out applications.
- 3-State Outputs: Enables bus-oriented applications, preventing bus contention and reducing power consumption.
- Advanced 74ALVCH Family: Provides low propagation delay and high-speed operation for demanding applications.
High-Speed Bus Interfacing
Use the 74ALVCH16825DLR to buffer address and data lines between a low-voltage FPGA (1.8V/2.5V) and a 3.3V memory bus. The 3-State outputs allow multiple devices to share the bus without contention.
Signal Buffering for High-Fan-Out Clocks
Buffer clock signals to multiple loads (e.g., multiple ADCs or DSPs) without degrading signal integrity. The 24mA drive capability ensures fast edge rates even with high capacitive loads.
Level Shifting in Mixed-Voltage Systems
Interface a 1.8V microcontroller to a 3.3V peripheral. The wide supply range (1.65V to 3.6V) allows the buffer to operate at the higher voltage while accepting low-voltage inputs, providing a simple level-shifting solution.
Memory Address/Data Demultiplexing
In systems with multiplexed address/data buses, this buffer can be used to demultiplex and drive separate address and data lines, improving timing margins and reducing loading on the source.
Industrial Control I/O Expansion
Drive multiple optocouplers or relay drivers from a low-voltage logic controller. The high current output (24mA) can directly drive these loads, reducing the need for external driver transistors.
Portable Electronics Power Management
Buffer control signals for power management ICs (PMICs) in battery-powered devices. The low-voltage operation (1.65V) minimizes power consumption, extending battery life.
