SN74LS390N Description

Short technical summary and product information.

The SN74LS390N from Texas Instruments is a dual 4-bit decade counter IC. This component is designed for digital logic applications and offers flexibility with its dual counter configuration.

 

Key electrical specifications include an operating voltage range of 4.75V to 5.25V and a maximum count frequency of 35 MHz. The counter features a negative edge trigger and asynchronous reset capabilities. It is constructed with a bipolar LS technology family.

 

Packaged in a 16-PDIP through-hole configuration, the SN74LS390N is suitable for applications requiring robust component mounting. The operating temperature range is from 0°C to 70°C, making it suitable for various commercial environments.

 

This device contains eight master-slave flip-flops and additional gating to implement two individual four-bit counters. The dual divide-by-two and divide-by-five counters can be used to implement cycle lengths up to divide-by-100. When connected as a bi-quinary counter, the separate divide-by-two circuit can provide symmetry at the final output stage.
