That extra margin matters when the host processor's read strobe is tight or when you're running near the 15 MHz data-rate ceiling. The C67401AN shares the same 40 ns access time but is 64 x 4 wide — one bit narrower. If your data path is 5 bits wide, the C67402AN is the correct width; dropping to the 4-bit variant would require a second device or software packing. ## Where it fits — and where it doesn't The 0 °C to 70 °C commercial temperature range limits this part to indoor, temperature-controlled environments — office equipment, lab instruments, or telecom racks with HVAC. It is not rated for industrial motor drives or outdoor enclosures. The 190 mA maximum supply current is drawn from the 5 V rail; size the 5 V regulator for that peak plus any additional loads on the same bus. Expansion is width-only (cascading for wider words, not deeper FIFO depth), so if you need more than 64 words, look at a deeper FIFO family or a different architecture.","metaTitle":"C67402AN FIFO 64x5 Asynchronous 40ns 16-DIP","metaDescription":"C67402AN asynchronous FIFO, 64 x 5, 40 ns access time, 15 MHz data rate, 5 V supply, 16-PDIP.
