DEVICE OPERATION

Read

Data stored in the CAT28C16A is transferred to the data

bus when WE is held high, and both OE and CE are held

low. The data bus is set to a high impedance state when

either CE or OE goes high. This 2-line control architec-

ture can be used to eliminate bus contention in a system

environment.
