DM74161AN is listed in the Counter Dividers range at ChipApex. The manufacturer field lists National Semiconductor. Its product description is IC BINARY COUNTER 4-BIT 16DIP. Review the specifications below when checking this part for your BOM.
The DM74161AN is a synchronous 4-bit binary counter manufactured by National Semiconductor. It operates within a voltage range of 4.75V to 5.25V and features a count rate of 25 MHz. The component utilizes TTL technology and is housed in a 16-pin plastic DIP package with dual through-hole terminals spaced at 2.54 mm. Designed for commercial temperature ranges, it supports reliable digital signal processing applications.
Verify the specific datasheet version from National Semiconductor or Texas Instruments archives. Confirm that the 25 MHz count rate specification aligns with your system requirements. Ensure the 16-pin DIP package matches your PCB footprint. Check for RoHS compliance status as indicated in official documentation.
Select this component when synchronous 4-bit counting is required with TTL compatibility. Consider the 25 MHz speed limit for high-frequency designs. Verify the 5V operating voltage range fits your power supply. The DIP-16 package is suitable for prototyping or through-hole manufacturing processes.
This part belongs to the National Semiconductor 74161 series of synchronous counters. It is functionally related to the DM74163AN but differs in reset behavior. The DM74141N listed in some sources is a distinct gas discharge display driver and should not be confused with this counter IC.
Consult official substitution guides for equivalent synchronous 4-bit counters. Verify pinout compatibility before replacing. Cross-reference with Texas Instruments documentation for updated alternatives.
