DM74LS90N DATASHEET PDF

Features, Applications Each of these monolithic counters contains four masterslave flip-flops and additional gating to provide a divide-bytwo counter and a three-stage binary counter for which the count cycle length is divide-by-five for the DM74LS To use their maximum count length decade or four bit binary , the B input is connected to the QA output. The input count pulses are applied to input A and the outputs are as described in the appropriate truth table. A symmetrical divide-by-ten count can be obtained from the DM74LS90 counters by connecting the QD output to the A input and applying the input count to the B input which gives a divide-by-ten square wave at output QA. Specify by appending the suffix letter "X" to the ordering code.

The input count pulses are applied to input A and the outputs are as described in the appropriate truth table. A symmetrical divide-by-ten count can be obtained from the DM74LS90 counters by connecting the QD output to the A input and applying the input count to the B input which gives a divide-by-ten square wave at output QA.

Specify by appending the suffix letter "X" to the ordering code. Note 2: Output QD is connected to input A for bi-quinary count. Note 3: Output QA is connected to input B. The J and K inputs shown without connection are for reference only and are functionally at a high level. The device should not be operated at these limits. The parametric values defined in the "Electrical Characteristics" table are not guaranteed at the absolute maximum ratings.

The "Recommended Operating Conditions" table will define the conditions for actual device operation.
