7490 Decade and Binary Counter

7490 Description

DM5490 DM7490A DM7493A Decade and Binary Counters www.DataSheet4U.com July 1992 DM5490 DM7490A DM7493A Decade and Binary Counters General Descript.
Each of these monolithic counters contains four masterslave flip-flops and additional gating to provide a divide-bytwo counter and a three-stage binar.

7490 Features

* Y Typical power dissipation 90A 145 mW 93A 130 mW Y Count frequency 42 MHz Connection Diagrams Dual-In-Line Package TL F 6533
* 1 Order Number DM5490J DM5490W or DM7490AN See NS Package Number J14A N14A or W14B Dual-In-Line Package Order Number DM7493AN See NS Package Number N14A TL F 6

7490 Applications

* 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 90A counters by connecting
