About this component
Four-bit one-hot ring counter. RESET synchronously seeds 0001; enabled rising edges rotate Q3→Q0→Q1→Q2→Q3, and any invalid state recovers to 0001 on the next enabled edge.
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 defined logic-high output.
5 V
Timing and state
2 parameters
TPD
Propagation delay
Clock-to-output propagation delay.
