74HC161PW-Q100J

Counter Dividers Overview

The Nexperia 74HC161PW-Q100J is a synchronous presettable 4-bit binary counter with an asynchronous reset, housed in a TSSOP16 package. It operates on a positive-edge triggered clock and features parallel data loading capabilities via dedicated inputs. The device includes two count enable inputs for cascading and a terminal count output. It complies with AEC-Q100 Grade 1 standards, supporting supply voltages from 2.0 V to 6.0 V and operating temperatures between -40 °C and +125 °C.

Counter Dividers Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Synchronous counting with internal look-ahead carry for simplified cascading
• Asynchronous master reset function independent of clock signals
• High noise immunity with latch-up performance exceeding specified limits

Counter Dividers Applications

• Automotive electronic systems requiring robust logic control
• Digital timing and sequencing circuits
• Frequency division applications
• Presettable counters in industrial instrumentation

Counter Dividers Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the necessary automotive reliability standards for the intended application environment. Ensure compatibility with system voltage levels and temperature ranges before finalizing procurement specifications.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with asynchronous reset is required in a compact surface-mount package. Consider its wide supply voltage range and high noise immunity for environments with electrical interference. Verify that the TSSOP16 footprint aligns with the PCB layout constraints.

Counter Dividers Part Context

This part belongs to the 74HC161-Q100 series, designed specifically for automotive applications. It represents a standard CMOS logic family member adapted for high-reliability requirements. The Q100 designation indicates adherence to strict automotive quality and reliability standards set by the Automotive Electronics Council.

Counter Dividers Replacement Considerations

Check for direct equivalents within the same logic family that share identical pinouts and functional characteristics. Ensure any substitute maintains the same AEC-Q100 qualification status if automotive use is required.
