The SN74ALVCH16646DL is a high-performance 16-bit non-inverting transceiver from the 74ALVCH logic family. It features two 8-bit channels with 3-state outputs, providing bidirectional data flow for bus-oriented systems. Operating from 1.65V to 3.6V, it supports low-voltage applications while delivering 24mA of output drive. The 56-BSSOP package is ideal for space-constrained designs. Typical applications include memory interfacing, level shifting, and high-speed data buffering in servers, telecom, and portable electronics.
- 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 reliable signal transmission over long PCB traces and multiple loads.
- 3-State Outputs: Enables bus sharing and isolation, preventing data corruption in multi-master systems.
- Non-Inverting Architecture: Preserves signal polarity, reducing design complexity and potential logic errors.
High-Speed Bus Interfacing
Use the SN74ALVCH16646DL to interface between a low-voltage FPGA (1.8V/2.5V) and a 3.3V memory bus. The 3-state outputs prevent bus contention and allow multiple devices to share the same data lines.
Level Shifting in Mixed-Voltage Systems
With a wide supply range of 1.65V to 3.6V, this transceiver can act as a bidirectional level shifter, enabling communication between 1.8V sensors and 3.3V microcontrollers without additional circuitry.
Server and Telecom Backplane Drivers
In high-speed networking equipment, this IC buffers address/data lines between line cards and the backplane. Its 24mA output drive ensures signal integrity over longer traces.
Bidirectional Data Multiplexing
Implement a data bus switch in a dual-processor system. The 3-state outputs allow either CPU to drive the shared memory bus, controlled by the direction and output enable pins.
Portable Electronics Power Management
In battery-powered devices, the low-voltage operation (1.65V) reduces dynamic power consumption, extending battery life while maintaining high-speed data transfer between the application processor and peripherals.
Industrial Control Module Isolation
Use this transceiver to buffer control signals between a PLC's logic core and its I/O modules. The 3-state outputs allow safe disconnection of modules during hot-swapping.
