The SN74LS90DR from Texas Instruments is a versatile decade counter IC belonging to the LS technology family. This component features four master-slave flip-flops and additional gating, enabling it to function as a divide-by-two counter and a three-stage binary counter with a divide-by-five count cycle length. It is designed for surface mounting and comes in a 14-SOIC package.
Key electrical characteristics include a typical power dissipation of 45 mW and an operating voltage range of 4.75V to 5.25V. The counter operates on a negative edge trigger and supports asynchronous reset. Its high-speed capability is indicated by a count rate of 42 MHz and propagation delay (tpd) between 10-50ns.
The SN74LS90DR is suitable for applications requiring digital counting and frequency division. Its design includes gated zero reset and gated set-to-nine inputs, making it useful for BCD nine's complement applications. The device operates within a temperature range of 0°C to 70°C.
