Part SN54LS390
Description DUAL DECADE COUNTER / DUAL 4-STAGE BINARY COUNTER
Feature DUAL DECADE COUNTER; DUAL 4-STAGE BINARY COUNTER The SN54 / 74LS390 and SN54 / 74LS393 each contain a pair of high-spe ed 4-stage ripple counters.
Each half o f the LS390 is partitioned into a divid e-by-two section and a divide-by five s ection, with a separate clock input for each section.
The two sections can be connected to count in the 8.
4.
2.
1 BCD c ode or they can count in a biquinary se quence to provide a square wave (50% du ty cycle) at the final output.
Each hal f of the LS393 operates as a Modulo-16 binary divider, with the last three sta ges triggered in a ripple fashion.
