Description
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.
