產品總覽

The 74HCT40105D is a 4-bit x 16-word FIFO Register that can store sixteen 4-bit words. It can handle input and output data at different shifting rates. This feature makes it particularly useful as a buffer between asynchronous systems. Each word position in the register is clocked by a control flip-flop, which stores a marker bit. A logic 1 signifies that the data at that position is filled and a logic 0 denotes a vacancy in that position. The control flip-flop detects the state of the preceding flip-flop and communicates its own status to the succeeding flip-flop. When a control flip-flop is in the logic 0 state and sees a logic 1 in the preceding flip-flop, it generates a clock pulse. The clock pulse transfers data from the preceding four data latches into its own four data latches and resets the preceding flip-flop to logic 0. The first and last control flip-flops have buffered outputs.
  • Independent asynchronous inputs and outputs
  • Expandable in either direction
  • Reset capability
  • Status indicators on inputs and outputs
  • TTL Input level
  • Complies with JEDEC standard No. 7A
