GENERAL DESCRIPTION
The 74HC/HCT40105 are high-speed Si-gate CMOS
devices and are pin compatible with the “40105” of the
“4000B” series. They are specified in compliance with
JEDEC standard no. 7A.
The 74HC/HCT40105 are first-in/first-out (FIFO) “elastic”
storage registers that can store sixteen 4-bit words. The
“40105” is capable of handling 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 “1” signifies that the position’s
data is filled and a “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 “0”
state and sees a “1” in the preceding flip-flop, it generates
a clock pulse that transfers data from the preceding four
data latches into its own four data latches and resets the
preceding flip-flop to “0”. The first and last control flip-flops
have buffered outputs. Since all empty locations “bubble”
automatically to the input end, and all valid data ripples
through to the output end, the status of the first control
flip-flop (data-in ready output - DIR) indicates if the FIFO is
full, and the status of the last flip-flop (data-out ready
output - DOR) indicates if the FIFO contains data. As the
earliest data is removed from the bottom of the data stack
(output end), all data entered later will automatically ripple
toward the output.
