The SN74ALVCH16245DGG is a 16-bit non-inverting transceiver from Texas Instruments, part of the 74ALVCH low-voltage CMOS family. It operates from 1.65V to 3.6V and provides 3-State outputs with 24mA source and sink capability. This 2-channel (16-bit) device enables bidirectional data transfer between two low-voltage buses. The 48-TFSOP package is ideal for space-constrained designs. Typical applications include DDR memory buffering, FPGA interfacing, and portable electronics. Its wide temperature range (-40°C to 85°C) makes it suitable for automotive and industrial use.
- Low-Voltage Operation (1.65V-3.6V): Compatible with modern low-power logic and processors.
- High Drive Current (24mA): Drives capacitive loads and long traces effectively.
- Bidirectional 16-Bit Width: Simplifies bus design and reduces component count.
- Bus-Hold Circuitry: Eliminates the need for external pull-up resistors on unused inputs.
