SN74LS593N

Counter Dividers Overview

The SN74LS593N is an 8-bit binary counter manufactured by Texas Instruments, belonging to the SN74LS logic family. It features a 20-pin PDIP package and operates within a supply voltage range of 4.75 V to 5.25 V. The device supports an up-counting sequence with synchronous reset functionality and utilizes positive-edge triggering for clock inputs. Designed for through-hole mounting, it functions reliably across an operating temperature range of 0°C to +70°C.

Counter Dividers Feature Summary

• Provides 8-bit binary counting capability with a unidirectional up-counting sequence.
• Features synchronous reset control for reliable state initialization.
• Utilizes positive-edge triggered flip-flops for precise timing synchronization.

Counter Dividers Applications

• Digital frequency division circuits
• Event counting systems
• Timing sequence generation

Counter Dividers Procurement Notes

Verify the specific ordering suffix against the Package Option Addendum to confirm the exact physical package type and manufacturing status. Ensure the selected variant matches the required lead finish and moisture sensitivity level for the intended assembly process. Cross-reference the active production status with current availability requirements before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when an 8-bit binary counter with synchronous reset is required in a standard TTL environment. The LS logic series offers a balance of speed and power consumption suitable for general-purpose digital applications. Confirm that the 20-pin PDIP package aligns with the printed circuit board layout and mechanical constraints of the design.

Counter Dividers Part Context

This part belongs to the SN74LS592/593 family of binary counters. While the SN74LS592 provides asynchronous reset, the SN74LS593 variant specifically incorporates synchronous reset logic. Both devices share similar electrical characteristics and pinout configurations, differing primarily in their reset control mechanisms and internal feedback paths for cascading operations.

Counter Dividers Replacement Considerations

SN74LS592N serves as a functional alternative if asynchronous reset behavior is acceptable instead of synchronous reset. Other compatible options include SN74LS593DWR for surface-mount applications or SNJ54LS593J for military-grade specifications requiring extended temperature ranges.

Counter Dividers FAQ

What is the trigger type for the SN74LS593N?

The SN74LS593N uses positive-edge triggered flip-flops for its clock input.

How does the reset mechanism work in this counter?

It employs a synchronous reset mechanism, meaning the reset action occurs on the active clock edge rather than asynchronously.
