SN74HC161APWR

Counter Dividers Overview

The SN74HC161APWR is a synchronous 4-bit binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports clock frequencies up to 36 MHz. The device features asynchronous reset, synchronous parallel load, and ripple clock outputs. It is housed in a 16-TSSOP surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with positive-edge triggering
• Asynchronous master reset for immediate clearing of all stages
• Synchronous parallel data loading capability via dedicated inputs
• Ripple clock output for cascading multiple counter stages

Counter Dividers Applications

• Digital timing and sequencing circuits
• Frequency division networks
• Event counting systems
• Pulse generation logic

Counter Dividers Procurement Notes

Verify the specific suffix APWR confirms the TSSOP-16 package and tape-and-reel shipping format. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the 2V to 6V operating voltage aligns with your system's power rails before integration.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter is required in a surface-mount design. The HC series offers standard CMOS performance suitable for general-purpose digital logic. Consider the TSSOP-16 footprint if board space is limited compared to through-hole alternatives like the DIP-16 variant.

Counter Dividers Part Context

This part belongs to the SN74HC161 family of synchronous 4-bit binary counters. It is functionally compatible with other industry-standard 74HC161 devices but is specifically packaged in a 16-pin Thin Shrink Small Outline Package (TSSOP) for automated surface-mount assembly.

Counter Dividers Replacement Considerations

SN74HC161PW: Same logic function in a 16-TSSOP package. SN74HC161N: Equivalent function in a 16-PDIP through-hole package. SN74HC161D: Equivalent function in a 16-SOIC surface-mount package.
