Frequently Asked Questions
What are the key electrical specifications of the SN74ALS804ADW?
The SN74ALS804ADW features output high current IOH of 15mA at VOH=2V and output low current IOL of 24mA at VOL=0.5V. It supports a 50pF load capacitance and operates in the ALS logic family, offering a balance of speed and low power consumption typical of Advanced Low-power Schottky devices.
What package type does the SN74ALS804ADW use and what are its dimensions?
The SN74ALS804ADW is housed in a 20-pin SOIC package (JESD-30 code R-PDSO-G20), a standard surface-mount package. This makes it suitable for high-density PCB layouts. The wide-body SOIC format (DW suffix) provides good thermal performance and ease of automated assembly.
What applications is the SN74ALS804ADW suitable for?
The SN74ALS804ADW is suitable for bus driving, address decoding, clock signal buffering, and general glue logic in digital systems. Its high output drive capability makes it ideal for industrial control systems, computing backplanes, telecommunications equipment, and embedded designs requiring reliable NAND gate logic with stronger drive than standard TTL gates.
What is a suitable replacement or alternative for the SN74ALS804ADW?
Suitable alternatives include the SN74LS804, SN74F804, and 74HC series NAND drivers for lower power applications. The 74ALS804 from other manufacturers (Fairchild, Philips) is also pin-compatible. For modern designs, the 74VHC series offers improved speed and lower supply voltage operation while maintaining functional compatibility.
