74LS161AP-E

Counter Dividers Overview

The HD74LS161AP-E is a synchronous 4-bit binary counter manufactured by Renesas Electronics Corporation. It operates within the standard 5V drive bipolar general-purpose logic IC family, which has an established market history exceeding thirty years. The device features direct clear functionality and supports parallel load operations. It is housed in a 16-pin SOIC package (SOP16) with a maximum operating temperature of 85 °C. The component functions as a binary counter with up-counting direction and synchronous operation mode.

Counter Dividers Feature Summary

• Provides synchronous 4-bit binary counting capabilities with direct clear function
• Supports parallel data loading for flexible address or state initialization
• Compatible with standard 5V drive bipolar logic families

Counter Dividers Applications

• Construction of microprogram control units as micro-address registers
• Digital frequency division circuits
• Pulse generation and timing sequences

Counter Dividers Procurement Notes

Verify that the specific suffix 'E' aligns with the manufacturer's current designation standards for the HD74LS161 series. Confirm RoHS compliance status and lead times directly with authorized distributors, as support for this legacy bipolar series may be limited to existing customers who have already adopted these products.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter with direct clear is required for 5V logic systems. Ensure the design accommodates the bipolar technology characteristics and the 16-pin SOIC footprint. Verify that the 85 °C maximum operating temperature meets the environmental requirements of the target application.

Counter Dividers Part Context

This part belongs to the HD74LS160/161 series of Renesas Electronics, representing a long-standing line of 5V bipolar logic integrated circuits. These components are widely recognized for their reliability and high market penetration in industrial and educational digital electronics applications over several decades.

Counter Dividers Replacement Considerations

Check for cross-reference compatibility with other manufacturers' LS161 variants such as SN74LS161. Verify pinout and electrical parameter equivalence before substitution.
