SN74LS161AML

Counter Dividers Overview

The SN74LS161AML is a 4-bit synchronous binary counter from the LS logic series, manufactured by onsemi. It features positive edge triggering and an asynchronous clear function. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a typical count rate of 35 MHz. It includes two count enable inputs for high-speed expansion and a fully decoded terminal count output. The component is housed in a SOIC-16 package.

Counter Dividers Feature Summary

• Synchronous counting and loading with edge-triggered operation
• Asynchronous clear input for immediate reset
• Two count enable inputs designed for high-speed synchronous expansion
• Fully decoded terminal count output

Counter Dividers Applications

• Frequency division circuits
• Memory addressing systems
• Digital counters requiring modulo 16 operation

Counter Dividers Procurement Notes

Verify that the specific suffix 'AML' corresponds to the SOIC-16 package and commercial temperature grade as documented in the official onsemi datasheet. Confirm RoHS compliance status and ensure the ordering part number matches the exact manufacturer specification sheet to avoid pinout or electrical characteristic mismatches.

Counter Dividers Selection Notes

Select this component when a 4-bit synchronous binary counter with asynchronous reset is required. It is suitable for designs needing high-speed expansion capabilities via dedicated count enable inputs. Ensure the application environment stays within the specified operating temperature range and supply voltage limits defined in the datasheet.

Counter Dividers Part Context

This part belongs to the SN74LS161A family of high-speed MSI building blocks. It is functionally compatible with other manufacturers' SN74LS161 variants but may differ in packaging or specific electrical parameters. The LS series offers standard TTL compatibility with improved speed over original 74 series devices.

Counter Dividers Replacement Considerations

Compatible substitutes include SN74LS161AN (Texas Instruments) and DM74LS161N (National Semiconductor). Verify package type compatibility, as these alternatives may be available in DIP packages instead of SOIC.
