Quality Control: Learn More
The Intel QD8237A-4 is a 4-channel Direct Memory Access (DMA) controller operating at up to 4MHz. This MOS technology component, housed in a 40-pin CDIP package (JESD_30 Code R-GDIP-T40), features an 8-bit external data bus and a 16-bit address bus, providing compatibility with 8080 and 8085 microprocessors. Designed for through-hole mounting, it operates within a supply voltage range of 4.75V to 5.25V with a nominal 5V requirement and a maximum supply current of 150mA. The QD8237A-4 is suitable for applications requiring efficient data transfer, commonly found in legacy computing systems, industrial control, and data acquisition interfaces. Its ceramic, glass-sealed construction ensures reliability in operating temperatures from 0°C to 70°C.
