About this component
Inspectable four-word by four-bit read-only memory with editable numeric contents. A0 is the least-significant address bit; active-high OE enables a combinational read and low OE forces Q0–Q3 low.
Parameters
Logic levels
2 parameters
VTH
Input threshold
Voltage at or above which an input is interpreted as logic high.
2.5 V
VHIGH
High output voltage
Voltage driven for a logic-high output.
5 V
