ON Semiconductor MC74HC173N Quad D-Type Flip-Flop with Clear

The MC74HC173N is a high-speed, quad D-type flip-flop integrated circuit produced by ON Semiconductor. This device is part of the 74HC family, which indicates that it is a high-speed CMOS device designed to operate with the same functionality as the older 74LS TTL family but with the lower power consumption and higher speed performance of CMOS technology.

Each flip-flop in the MC74HC173N has individual clear and clock inputs with a common enable. The device is typically used for storing binary information and has the capability to transfer data from the D inputs to the Q outputs on the rising edge of the clock pulse, provided that the enable input is active. The clear input, when taken low, sets all the Q outputs low, regardless of other inputs, which is particularly useful for initializing or resetting the system during startup or after an error.

The MC74HC173N is packaged in a standard 16-pin DIP (Dual In-line Package), making it suitable for breadboard prototyping as well as for use in commercial product development. It operates over a wide voltage range from 2V to 6V and features low input current, which contributes to its low power consumption. This makes it a good choice for battery-operated devices and other low-power applications.

Key features of the MC74HC173N include:

• Quad D-type flip-flops with clear
• Output drive capability of 10 LSTTL loads
• Typical tpd of 13 ns
• Low power consumption: 80 μA maximum ICC
• Wide operating voltage range: 2V to 6V
• Low input current: 1 μA maximum
• Standard 16-pin DIP package

This device is ideal for use in applications that require the capture and retention of binary data, including registers, counters, and memory devices. The MC74HC173N's robustness and reliability, combined with ON Semiconductor's commitment to quality, make it a preferred choice for designers and engineers looking to implement flip-flops in their digital logic circuits.
