The NXP Semiconductors 74HCT7403D is a 64x4 bit asynchronous FIFO memory device. Featuring a 108ns maximum access time, this CMOS component operates with a 5V nominal supply voltage, ranging from 4.5V to 5.5V, and supports a maximum clock frequency of 12MHz. The 74HCT7403D offers a memory organization of 64 words by 4 bits, providing a total memory density of 256 bits. It includes register-based buffering with a 2.7µs bubble back characteristic and 3-state outputs controlled by an output enable pin. This surface-mount device is housed in a 16-lead PDSO (Small Outline Package) with a 1.27mm terminal pitch. Its operational temperature range is -40°C to +125°C. This component is suitable for applications in industrial automation, telecommunications infrastructure, and consumer electronics requiring robust data buffering.
