Frequently Asked Questions
What is the supply voltage range and propagation delay of the SN74ALS32DR?
The SN74ALS32DR operates on a supply voltage range of 4.5V to 5.5V, compatible with standard 5V TTL and ALS logic systems. It features a load capacitance rating of 50pF and delivers the fast switching performance characteristic of the ALS (Advanced Low-power Schottky) logic family, typically offering propagation delays in the range of a few nanoseconds.
What are the typical applications for the SN74ALS32DR quad OR gate?
The SN74ALS32DR is commonly used in address decoding, interrupt request logic, bus enable circuits, and signal combining in microprocessor and microcontroller systems. Its four independent 2-input OR gates make it suitable for industrial control boards, communication interfaces, test equipment, and any digital design requiring combinational logic functions.
What package does the SN74ALS32DR come in, and are there pin-compatible alternatives?
The SN74ALS32DR is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package with a JESD-30 code of R-PDSO-G14, making it suitable for surface-mount PCB assembly. Pin-compatible alternatives include the SN74LS32DR (Low-power Schottky) and SN74HCT32DR (High-speed CMOS), all sharing the same 14-pin OR gate pinout for easy drop-in replacement.
Is the SN74ALS32DR RoHS compliant and what is the lead-free status?
Yes, the SN74ALS32DR is fully RoHS compliant. It carries a Pb-free code of 'Yes' and a JESD-609 code of e4, confirming it meets international environmental standards for restriction of hazardous substances. This makes it suitable for use in modern consumer electronics, industrial equipment, and any application requiring lead-free components.
