DESCRIPTION

The HCC40105B (extended temperature range) and

HCF40105B (intermediate temperature range) are

monolithic integrated circuits, available in 16-lead dual

in-line plastic or ceramic package.

The HCC/HCF40105B is a low-power first-in-first-out

(FIFO) ”elastic” storage register that can store 16 4-bit

words. It is capable of handling input and output data

at different shifting rates. This feature makes it particu-

larly useful as a buffer between asynchronous sys-

tems. Each word position in the register is clocked by

a control flip-flop, which stores a marker bit. A ”1” sig-

nifies 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 con-

trol 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 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
