Output Register

General Description

The ’F410 is a register-oriented high-speed 64-bit Read/
Write Memory organized as 16-words by 4-bits. An edge­triggered 4-bit output register allows new input data to be
written while previous data is held. TRI-STATE outputs are
provided for maximum versatility. The ’F410 is fully compati­ble with all TTL families.

Functional Description

Write OperationÐWhen the three control inputs, Write En-

able (WE

), Chip Select (CS), and Clock (CP), are LOW the

information on the data inputs (D

0–D3

) is written into the

memory location selected by the address inputs (A

0–A3

). If

the input data changes while WE

,CS, and CP are LOW, the
contents of the selected memory location follow these
changes, provided setup and hold time criteria are met.

Read OperationÐWhenever CS

is LOW and CP goes from
LOW-to-HIGH, the contents of the memory location select­ed by the address inputs (A

0–A3

) are edge-triggered into

the Output Register.

The (OE

) input controls the output buffers. When OE is

HIGH the four outputs (Q

0–Q3

) are in a high impedance or

OFF state; when OE

is LOW, the outputs are determined by

the state of the Output Register.
