Decade Counter IC – 74HC90

Decade Counter IC – 74HC90

The 74HC Series 74HC90 Decade Counter IC having 4.75 to 5.25V Supply Voltage with 8mA Low Level and – 0.4mA High-Level Output Current. It is a simple counter, it can count from 0 to 9 cyclically in its natural mode. It counts the input pulses and the output is received as a 4-bit binary number through pins QA, QB, QC, and QD. The binary output is reset to 0000 at every tenth pulse and the count starts from 0 again.

Used For Power amplifiers, Small-signal amplifiers, Operational amplifiers, Microwave amplifiers, RF and IF amplifiers, Voltage comparators, Multiplier.
