What are the key features of 74ALVCH16271DLG4?
- 16-bit ALVCH logic family providing 1.65 V to 3.6 V operation with 3-state outputs and 24 mA drive capability for high-speed bus interfacing
- 12 configurable functions in a single device replacing multiple discrete logic ICs in bus multiplexing and demultiplexing applications
- 56-pin SSOP package balancing lead density and PCB space for wide data bus routing in network and computing backplane designs
What is 74ALVCH16271DLG4 used for?
74ALVCH16271DLG4 serves as a universal bus driver in high-speed digital systems such as network switching equipment, server backplanes, and FPGA interface boards where 16-bit data path multiplexing is required. Its 3-state outputs allow multiple devices to share a common bus without contention, enabling flexible bus arbitration in memory controllers and DSP peripherals. The ALVCH family's low supply voltage of 1.65 V to 3.6 V suits modern low-power ASIC and FPGA I/O integration.

Frequently Asked Questions
What supply voltage range does 74ALVCH16271DLG4 support and what is the output sink current capability?
74ALVCH16271DLG4 operates from 1.65 V to 3.6 V supply voltage and provides a maximum output sink current of 24 mA per pin, enabling it to drive bus lines with multiple load devices. The 3-state output control allows the device to be disabled and share a 16-bit bus with other drivers without bus contention.
How does the 12-function flexibility of 74ALVCH16271DLG4 reduce component count in bus multiplexing designs?
By integrating 12 selectable logic functions including multiplexing, demultiplexing, and bus driving in a single 56-pin SSOP, 74ALVCH16271DLG4 can replace 3 to 4 separate quad-gate or octal-buffer ICs in a typical 16-bit bus design. This consolidation reduces BOM line items, simplifies PCB routing, and lowers assembly cost in server and networking applications.
For an FPGA-based design needing 16-bit bus bridging between 1.8 V and 3.3 V domains, when should 74ALVCH16271DLG4 be considered?
When an FPGA's 1.8 V I/O bank needs to drive a 3.3 V legacy bus with 24 mA capable 3-state outputs, 74ALVCH16271DLG4 fits the 1.65 V to 3.6 V supply range and can operate from the FPGA's 1.8 V rail while still delivering sufficient current to the 3.3 V load, avoiding the need for a separate level-shift IC in the signal path.
