The NXP Semiconductors N74F189AD is a 16x4 standard asynchronous SRAM with an 8ns maximum access time. This TTL-compatible memory component features inverted outputs and 3-state output characteristics. It operates with a supply voltage range of 4.5V to 5.5V, typically 5V, and has a maximum supply current of 80mA. The N74F189AD is housed in a 16-pin PDSO (Plastic Dual Small Outline) package, conforming to the R-PDSO-G16 standard, with a terminal pitch of 1.270mm. Operating within a temperature range of 0°C to 70°C, this surface-mount device is suitable for applications in industrial automation and telecommunications. The memory organization is 16 words by 4 bits, providing a total density of 64 bits.
