DM5490 Decade and Binary Counters

DM5490 Description

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

DM5490 Features

* Y Y Typical power dissipation 90A 145 mW 93A 130 mW 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 TL F 6533
* 2 Order Number DM7493AN See NS Pa

DM5490 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
