SN74LS93DR

Counter Dividers Overview

The SN74LS93DR is a four-bit binary counter integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features asynchronous reset functionality with negative-edge triggering. The device utilizes the LS logic series for standard TTL compatibility and is housed in a 14-SOIC surface-mount package. Designed for industrial reliability, it supports an operating temperature range from 0°C to +70°C.

Counter Dividers Feature Summary

• Provides synchronous four-bit binary counting capability using negative-edge triggered flip-flops.
• Features an asynchronous reset input that clears all outputs independently of the clock signal.
• Includes dedicated output pins (QA and QB) to facilitate cascading into higher-order counters.

Counter Dividers Applications

• Digital frequency division circuits
• Binary timing sequence generation
• Cascaded multi-stage counter systems

Counter Dividers Procurement Notes

Verify the specific suffix 'DR' confirms the SOIC-14 surface-mount package variant rather than the through-hole DIP version. Ensure the order specifies the commercial grade temperature rating suitable for standard operational environments. Confirm RoHS compliance status matches current manufacturing standards before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a compact surface-mount solution is required for basic binary counting tasks. It serves as a direct replacement for legacy through-hole designs where board space is limited. Consider the propagation delay characteristics inherent to the LS logic family when designing high-speed timing sequences.

Counter Dividers Part Context

This part belongs to the widely adopted 74LSxx series of logic devices, known for balancing power consumption with switching speed. The SN74LS93 specifically addresses the need for simple, reliable binary counting in digital systems without requiring complex programming or microcontroller resources.

Counter Dividers Replacement Considerations

The SN74LS93N is the equivalent through-hole PDIP-14 package variant. Other manufacturers produce functionally identical parts under the generic 74LS93 designation, provided pinouts match exactly.
