SN74LS93DRE4

Counter Dividers Overview

The SN74LS93DRE4 is a 4-bit binary counter integrated circuit belonging to the Texas Instruments SN54/74LS series. It features asynchronous reset functionality and negative-edge triggering for reliable counting operations. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum clock frequency of 42 MHz. Designed for surface-mount applications, it utilizes a 14-pin SOIC package with a standard width of 0.154 inches (3.90 mm). The component functions as a single-element, up-counting binary divider suitable for digital logic circuits requiring precise timing sequences.

Counter Dividers Feature Summary

• Asynchronous reset capability allows immediate clearing of count states independent of the clock signal.
• Negative-edge triggered operation ensures accurate synchronization with falling clock transitions.
• High-speed performance supports clock frequencies up to 42 MHz for rapid data processing.

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting sequences in control systems
• Timing generation modules

Counter Dividers Procurement Notes

Verify that the ordering suffix 'E4' confirms compliance with RoHS standards and specifies the tape-and-reel packaging format. Confirm the manufacturer designation matches Texas Instruments to ensure authenticity. Check the specific package variant against the required board layout dimensions. Ensure the component status is active or available through authorized distributors before finalizing procurement plans.

Counter Dividers Selection Notes

Select this component when a 4-bit binary counter with asynchronous reset is required for low-power TTL-compatible designs. The LS series offers a balance between speed and power consumption suitable for general-purpose logic applications. Consider the 14-pin SOIC package constraints during PCB layout planning. Verify that the operating temperature range meets the environmental requirements of the target system.

Counter Dividers Part Context

This part belongs to the widely adopted SN54/74LS family of logic integrated circuits. The SN74LS93 serves as a fundamental building block for sequential logic design. It provides a standardized interface for binary counting tasks across various industrial and consumer electronics platforms. The device complements other LS-series components like decoders and flip-flops in complex digital architectures.

Counter Dividers Replacement Considerations

SN74LS93DR is a compatible alternative from the same manufacturer offering identical logical functionality and pinout configuration. Both parts share the same LS series specifications and operational characteristics. Verify package compatibility and electrical parameters when substituting one for the other in existing designs.
