What are the key features of 74LVCH16244ADGGR?
- 16 independent 3-state outputs provide flexible bus isolation and backplane drive for high-density logic designs
- 5V-tolerant inputs allow direct interfacing between 3.3V logic and legacy 5V TTL buses without level-shift ICs
- 24mA output drive strength per channel enables long PCB trace driving and capacitive load tolerance up to 50pF
- Operating voltage range of 1.65V to 3.6V covers LVCMOS logic families across portable and industrial applications
- 48-pin TSSOP package delivers a high channel count in a compact 6.1mm x 12.5mm footprint
What is 74LVCH16244ADGGR used for?
The 74LVCH16244ADGGR is used in memory module address and data bus buffering, multi-board backplane systems, and FPGA I/O expansion where 16 simultaneous drive channels are needed at 3.3V. It also serves in test and measurement equipment that must bridge 5V legacy peripherals to modern 3.3V processor buses. Its 3-state outputs make it ideal for bidirectional bus arbitration schemes in embedded computing platforms.

Frequently Asked Questions
Can the 74LVCH16244ADGGR drive 5V TTL devices directly from a 3.3V supply rail?
Yes, all 16 inputs are 5V-tolerant, accepting logic-high signals up to 5.5V while the device operates from a 1.65V to 3.6V supply. Each output sources or sinks up to 24mA, meeting the drive requirements of most 5V TTL loads without additional level-shift components.
How many channels does this buffer provide, and what is the output drive current per channel?
The device integrates 16 independently controlled buffer channels arranged in two 8-bit groups. Each channel provides 24mA output sink and source current, giving sufficient drive for long PCB traces, bus capacitance up to 50pF per line, and low-impedance backplane environments.
What package does the 74LVCH16244ADGGR use, and how does it compare to SOIC packaging for high-density boards?
It uses a 48-pin TSSOP package with 0.5mm lead pitch measuring approximately 6.1mm x 12.5mm. Compared to a 48-pin SOIC which uses roughly 15.4mm x 7.5mm, the TSSOP footprint is about 40% smaller, enabling significantly higher buffer density on constrained PCBs such as server memory slots.
When is the 74LVCH16244ADGGR preferred over 8-bit buffers like 74LVC244 in a design?
The 16-bit width reduces the IC count by half compared to using two 74LVC244 8-bit buffers, cutting board space and BOM cost for 16-bit address or data buses. A single enable signal can control all 16 outputs simultaneously, simplifying glue logic and reducing signal routing complexity on multilayer PCBs.
