74LS189 64-Bit RAM with 3-State Output IC DIP-16 Package
The 74LS189 64-bit RAM with 3-State Output in a DIP-16 package is a compact static RAM (Random Access Memory) IC that provides 64 bits of storage, organized as 16 words of 4 bits each. This memory chip is part of the 74LS logic family, known for its high-speed performance and low power consumption. The 74LS189 is primarily used in applications that require small, high-speed data storage, such as digital counters, registers, and buffers in microprocessor-based systems. Each memory cell can retain data without a refresh signal, making it ideal for static applications. The IC has 3-state outputs, allowing for easy integration with other chips on a common bus without interference. The 74LS189’s 3-state outputs can either output data or enter a high-impedance state, controlled by an external enable signal. This feature is especially useful when the memory needs to share data buses with other components, as it prevents bus conflicts and allows smooth data flow across complex circuits.
