NIPPON PRECISION CIRCUITS—8

Output Enable

When OE is HIGH, DOUT0 to DOUT7 become high

impedance. Note that because RE operation is inde-

pendent of OE operation, the read address pointer

can be incremented even when the outputs are high

impedance.

TYPICAL APPLICATIONS

Note that at power-ON, the write address pointer and

read

address

pointer

positions

are

undeﬁned.

Accordingly, RW and RR reset cycles are required.

1H Delay Line

A 5120-word delay line can be realized by perform-

ing simultaneous write reset and read reset at power-

ON.

An n-word delay line (21 to 5210-word) can be real-

ized using any of the following methods.

1. Perform reset in sync with desired delay length.

2. Stagger RW and RR timing to desired delay

length.

3. Manipulate the write or read address pointer

using WE or RE to disable incrementing to

maintain sync with desired delay length.
