High-Speed CMOS Logic

4-Bit x 16-Word FIFO Register

February 1998 - Revised October 2003

Features

Description

• Independent Asynchronous Inputs and Outputs

• Expandable in Either Direction

• Reset Capability

The ’HC40105 and ’HCT40105 are high-speed silicon-gate

CMOS devices that are compatible, except for “shift-out”

circuitry, with the CD40105B. They are low-power ﬁrst-in-out

(FIFO) “elastic” storage registers that can store 16 four-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.

• Status Indicators on Inputs and Outputs

• Three-State Outputs

• Shift-Out Independent of Three-State Control

• Fanout (Over Temperature Range)

Each work position in the register is clocked by a control ﬂip-

ﬂop, which stores a marker bit. A “1” signiﬁes that the posi-

tion’s data is ﬁlled and a “0” denotes a vacancy in that posi-

tion. The control ﬂip-ﬂop detects the state of the preceding

• Wide Operating Temperature Range . . . -55 C to 125 C ﬂip-ﬂop. When a control ﬂip-ﬂop is in the “0” state and sees a

“1” in the preceeding 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 ripple through to the output end, the

status of the ﬁrst control ﬂip-ﬂop (DATA-IN READY) indicates

if the FIFO is full, and the status of the last ﬂip-ﬂop (DATA-

OUT READY) indicates if the FIFO contains data. As the

earliest data are removed from the bottom of the data stack

(the output end), all data entered later will automatically

propagate (ripple) toward the output.
