The 74AC299 is a 20-pin SOP (Small Outline Package) CMOS (Complementary Metal Oxide Semiconductor) device manufactured by STMicroelectronics. It is a 4-bit addressable latch with an asynchronous reset.Description:The 74AC299 is a 4-bit addressable latch with an asynchronous reset. It has an active low reset input and an active high enable input. The device has four data inputs, four data outputs, and four address inputs. The data outputs are latched on the rising edge of the enable input. The device has an open-drain output for active low output enable.Features: 4-bit addressable latch Asynchronous reset Active low reset input Active high enable input Four data inputs Four data outputs Four address inputs Open-drain output for active low output enableApplications:The 74AC299 is suitable for use in applications such as memory address decoding, data storage, and data transfer. It can also be used in microprocessor-based systems and programmable logic controllers.(For reference only)
