Bus direction is uni-directional — data flows one way through the register. It does not support FWFT (First-Word Fall-Through), programmable flags, or retransmit capability; the control logic is straightforward for simple buffering applications.","metaTitle":"CD74HCT40105E 74HCT FIFO, 64-bit (16x4), 16-DIP, Active","metaDescription":"CD74HCT40105E asynchronous FIFO register, 64-bit (16 x 4) memory, 4.5-5.5V supply, -55°C to 125°C range, 16-DIP package.
