The M74HC161M1R is a high-speed CMOS synchronous 4-bit binary counter manufactured by STMicroelectronics. It is fabricated using silicon-gate C2MOS technology and is pin-compatible with the 74 Series 161. This counter features a wide operating voltage range from 2V to 6V and a maximum clock frequency of 62 MHz at 6V.
Key features include low power dissipation with a quiescent current of only 4μA at 25°C, and high noise immunity. The device has symmetrical output impedance and balanced propagation delays. It includes two enable inputs (TE and PE) and a CARRY output, facilitating easy cascading of counters for N-bit counter implementations without external gates. All inputs are protected against static discharge and transient excess voltage.
The M74HC161M1R is supplied in a Surface Mount SOP package. Its operating temperature range is -55°C to 125°C, making it suitable for various industrial applications. The counter's synchronous preset capability and asynchronous clear function provide flexible control.
This component is ideal for digital logic designs requiring counting and data manipulation functions. Its robust construction and reliable performance make it a solid choice for embedded systems and control applications.
