DM54LS461 DM74LS461 Octal Counter
General Description
The LS461 is an 8-bit synchronous counter with parallel load clear and hold capability Two function select inputs (I0 I1) provide one of four operations which occur synchronously on the rising edge of the clock (CK)
The LOAD operation loads the inputs (D7 – D0) into the output register (Q7 – Q0) The CLEAR operation resets the output register to all LOWs The HOLD operation holds the previous value regardless of clock transitions The INCREMENT operation adds one to the output register when the carry-in input is TRUE (CI e LOW) otherwise the operation is a HOLD The carry-out (CO) is TRUE (CO e L...
