What are the key features of 74ALVC16244ADGGRE4?
- 16 non-inverting 3-state driver channels in a 48-pin TSSOP enable high-density bus buffering with individual enable-low control and 24 mA output drive
- ALVC logic family supports low-voltage operation compatible with 1.8 V to 3.3 V mixed-voltage systems for bus translation without external level shifters
- 3-state outputs with active-low enable per quad group allow multiple 74ALVC16244 devices to share a common 16-bit data bus without contention
- 50 pF load capacitance rating supports direct backplane and PCB trace driving at full ALVC switching speeds for high-throughput data transfers
What is 74ALVC16244ADGGRE4 used for?
74ALVC16244ADGGRE4 is used as a bus repeater and direction-fixed buffer in FPGA I/O expansion, DSP memory interfaces, and processor-to-peripheral bus isolators where 16 unidirectional channels are needed at low-voltage supply levels. Its 3-state outputs allow seamless insertion into shared 16-bit data buses in DDR memory controllers, PCI bus adapters, and industrial backplane systems operating at 1.8 V to 3.3 V. The 48-pin TSSOP footprint and tape-and-reel packaging support high-volume automated assembly in networking equipment and embedded computing boards.

Frequently Asked Questions
How many channels does 74ALVC16244ADGGRE4 provide and how are they controlled?
74ALVC16244ADGGRE4 provides 16 non-inverting driver channels organized into 4 groups of 4 bits, each group controlled by an active-low output-enable pin. This allows selective tri-stating of each 4-bit nibble independently, enabling flexible bus partitioning in 8-bit or 16-bit bus architectures at 24 mA sink current per output.
What supply voltage range does 74ALVC16244ADGGRE4 support for mixed 1.8 V to 3.3 V bus systems?
74ALVC16244ADGGRE4 from the ALVC logic family is designed for low-voltage operation from approximately 1.65 V to 3.6 V, making it compatible with 1.8 V, 2.5 V, and 3.3 V supply rails. Its input switching thresholds are compatible with LVCMOS and LVTTL signal levels, supporting direct interfacing between mixed-voltage subsystems in modern SoC and FPGA designs without external resistor networks.
Can 74ALVC16244ADGGRE4 drive multiple memory modules on a shared 16-bit address bus?
Yes, 74ALVC16244ADGGRE4 is rated for a 50 pF load capacitance per output channel and provides 24 mA of output sink current, sufficient to drive the combined capacitance of 2–4 SDRAM or flash memory devices on a shared 16-bit address or data bus. The 3-state outputs allow the driver to be tri-stated when the bus is held by another master, preventing contention in multi-master or banked memory designs.
What package does 74ALVC16244ADGGRE4 use and how does tape-and-reel availability affect production purchasing?
74ALVC16244ADGGRE4 is packaged in a 48-pin TSSOP with 0.5 mm pin pitch and supplied on tape-and-reel (T/R suffix) in quantities of 2500 units per reel. The T/R format is compatible with standard SMT pick-and-place machines, reducing setup time and component waste in high-volume board assembly for networking, industrial computing, and telecommunications equipment.
