7493 Decade and Binary Counters

7493 Description

DM74LS90 DM74LS93 Decade and Binary Counters June 1989 DM74LS90 DM74LS93 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.

7493 Features

* Y Typical power dissipation 45 mW Y Count frequency 42 MHz Connection Diagrams (Dual-In-Line Packages) TL F 6381
* 1 Order Number DM74LS90M or DM74LS90N See NS Package Number M14A or N14A TL F 6381
* 2 Order Number DM74LS93M or DM74LS93N See NS Package Number M14A or N14A C1995 N

7493 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 ’LS90 counters by connecti
