74LS90 Decade Counter IC – DIP-14 Package
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 DM74LS90. All of these counters have a gated zero reset and the DM74LS90 also has gated set-to-nine inputs for use in BCD nine’s complement applications.
This product is known as SN74LS90NE4, SN74LS90DR, SN74LS90N, SN74LS90DE4, SN74LS90D, 7490, 74LS90, 74LS90 Decade Counter IC, 74LS90 or 7490 IC-Decade Counter.
Features:
- A decade counter is a binary counter that is designed to count to 1010b.
- By changing the modes of Decade Counter IC, the chip can count up to other maximum numbers and return to zero.
- The Decade Counter IC consists of four master-slave JK flip-flops internally connected to provide a MOD-2 (count-to-2) counter and a MOD-5 (count-to-5) counter.
- Decade counter is one that counts in decimal digits, rather than binary. A decade counter may have each or other binary encodings.
