Features

Description

• Simultaneous and Independent Read and Write

Operations

The ’HC670 and CD74HCT670 are 16-bit register files

organized as 4 words x 4 bits each. Read and write address

and enable inputs allow simultaneous writing into one location

while reading another. Four data inputs are provided to store

the 4-bit word. The write address inputs (WA0 and WA1)

determine the location of the stored word in the register.

When write enable (WE) is low the word is entered into the

address location and it remains transparent to the data. The

outputs will reflect the true form of the input data. When (WE)

is high data and address inputs are inhibited. Data acquisition

from the four registers is made possible by the read address

inputs (RA1 and RA0). The addressed word appears at the

output when the read enable (RE) is low. The output is in the

high impedance state when the (RE) is high. Outputs can be

tied together to increase the word capacity to 512 x 4 bits.
