Frequently Asked Questions
What logic family and supply voltage does SN74ALS994DW use?
SN74ALS994DW belongs to the Advanced Low-power Schottky (ALS) logic family and operates from a 4.75V to 5.25V supply voltage, making it fully compatible with standard 5V TTL and CMOS system designs.
What are the 3-state outputs on SN74ALS994DW used for?
The 3-state outputs allow SN74ALS994DW to be connected directly to shared data buses. When outputs are disabled (high-impedance state), the device releases the bus, enabling multiple devices to share the same data lines without contention.
What package does SN74ALS994DW come in and what are the dimensions?
SN74ALS994DW is packaged in a 20-pin SOIC (DW) wide-body surface-mount package, suitable for automated PCB assembly and providing a compact footprint for high-density board designs.
What are the typical applications for SN74ALS994DW?
Typical applications include serial-to-parallel and parallel-to-serial data conversion, data bus buffering in microprocessor systems, pipeline registers in industrial controllers, and shift register chains in communication and data acquisition equipment.
How does SN74ALS994DW compare to 74LS and 74HC shift registers?
Compared to 74LS devices, SN74ALS994DW offers lower power consumption and improved noise margins. Compared to 74HC, it provides higher drive current and is better suited for mixed TTL/CMOS environments operating at 5V logic levels.
