SN74HC161PWT

Counter Dividers Overview

The SN74HC161PWT is a synchronous 4-bit binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and supports clock frequencies up to 60 MHz. The device features asynchronous reset, synchronous parallel load, and ripple clock outputs. It is housed in a 16-TSSOP package with a width of 4.40mm and functions 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 reset and synchronous parallel load capabilities
• Ripple clock output for cascading applications

Counter Dividers Applications

• Digital timing circuits requiring precise synchronization
• Frequency division networks
• Event counting systems

Counter Dividers Procurement Notes

Verify the specific suffix 'PWT' corresponds to the 16-TSSOP surface-mount package and tape-and-reel shipping configuration. Confirm RoHS compliance status and ensure the manufacturer designation matches Texas Instruments specifications before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a low-power CMOS 4-bit counter with synchronous control is required. Ensure the design accommodates the 2V to 6V supply range and verify that the TSSOP-16 footprint aligns with the PCB layout constraints.

Counter Dividers Part Context

This part belongs to the SN74HC161 family of synchronous binary counters. It shares functional logic with through-hole variants like the SN74HC161N but utilizes a surface-mount TSSOP package for automated assembly processes.

Counter Dividers Replacement Considerations

SN74HC163PW: Similar functionality but with synchronous reset instead of asynchronous.
