SN74ALS193ANS

Counter Dividers Overview

The SN74ALS193ANS is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments. It features dual clock inputs for independent up and down counting operations, along with a dedicated clear input to reset the device. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum propagation delay of 20 ns. It is housed in a 16-pin SOIC package and functions reliably across an operating temperature range of 0°C to +70°C.

Counter Dividers Feature Summary

• Supports synchronous 4-bit binary counting with separate up and down clock inputs
• Includes asynchronous master clear function for immediate state reset
• Compatible with standard TTL logic levels

Counter Dividers Applications

• Digital frequency division circuits
• Event counting systems
• Timing control logic

Counter Dividers Procurement Notes

Verify the specific suffix 'ANS' confirms the SOIC-16 surface-mount package and commercial temperature grade. Ensure the design accounts for the ALS series power consumption characteristics compared to standard LS counterparts. Confirm that the dual-clock architecture aligns with the system timing requirements before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a compact, low-power synchronous counter is required for binary applications. The ALS series offers improved speed over standard LS devices while maintaining lower power dissipation than AS series parts. Consider the SOIC package constraints for PCB layout and thermal management during selection.

Counter Dividers Part Context

This part belongs to the Texas Instruments SN74ALS family of advanced small-scale integration logic devices. It serves as a digital counter element within larger sequential logic systems. The SN74ALS193ANS provides a reliable solution for binary counting tasks where moderate speed and low power are prioritized over high-speed performance.
