SN74LS92N

Counter Dividers Overview

The SN74LS92N is a high-speed 4-bit ripple-type counter from the Texas Instruments LS logic series, housed in a 14-pin PDIP package. It features a divide-by-two section and a divide-by-six section triggered by HIGH-to-LOW clock transitions. The device supports asynchronous Master Reset and allows configuration as a divide-by-twelve or modulo-16 counter. Operating parameters include a supply voltage range of 4.75V to 5.25V, an operating temperature range of 0°C to 70°C, and a typical count rate of 42 MHz.

Counter Dividers Feature Summary

• Partitioned architecture with separate divide-by-two and divide-by-six sections for flexible counting modes
• Asynchronous gated Master Reset (Clear) functionality
• Compatible with BCD, bi-quinary, divide-by-twelve, and binary counting configurations

Counter Dividers Applications

• Digital frequency division circuits
• Modulo-N counter implementations
• Binary sequence generation systems

Counter Dividers Procurement Notes

Verify the specific manufacturer source, as ON Semiconductor also produces this part number. Confirm RoHS compliance status directly with the supplier, as documentation indicates it may be non-compliant for certain batches. Ensure the package type matches the required through-hole DIP-14 specification for your PCB layout.

Counter Dividers Selection Notes

Select this component when a dedicated divide-by-twelve or modulo-16 counter is required within standard TTL logic constraints. It serves as a direct functional alternative to the SN74LS90 and SN74LS93, offering distinct partitioning capabilities. Consider the 42 MHz typical speed and low power consumption characteristics for general-purpose digital timing applications.

Counter Dividers Part Context

This device belongs to the SN54/74LS9x family of counters, which includes the SN74LS90 (divide-by-five) and SN74LS93 (divide-by-eight). All members share similar architectural traits, featuring partitioned sections and asynchronous reset controls. The SN74LS92 specifically provides the divide-by-six stage necessary for creating twelve-step counting sequences.
