STMicroelectronics M74HC175M1R Quad D-Type Flip-Flop

The M74HC175M1R is a high-speed CMOS Quad D-Type Flip-Flop with clear, manufactured by STMicroelectronics. This integrated circuit is part of the HC family, which means it features the high noise immunity and low power consumption of CMOS technology along with the speed of operation equivalent to that of the LSTTL (Low-power Schottky Transistor-Transistor Logic).

Designed to be used in a wide array of applications, the M74HC175M1R consists of four edge-triggered flip-flops with individual D inputs and Q outputs. The clear function for all four flip-flops is achieved through a common input, which when taken to a high logic level, forces all Q outputs to a low logic level; this occurs independently of the clock input and the D inputs.

The device features a standard pinout, with inputs and outputs placed opposite each other, which simplifies board layout and design. The clock and clear inputs are equipped with protection circuits to prevent damage due to static discharge or excess transient voltage, making the device robust for use in a variety of electronic environments.

Key Features:

• High Speed: Typical clock frequency at 6MHz.
• Output Drive Capability: 10 LSTTL Loads.
• Outputs Directly Interface to CMOS, NMOS, and TTL.
• Low Input Current: 1μA maximum.
• Low Quiescent Current: 20μA maximum (if the inputs are not toggling).
• High Noise Immunity: VNIH = VNIL = 28% VCC (minimum).
• Wide Operating Voltage Range: 2V to 6V.
• Pin and Function Compatible with 74LS175.
• ESD Performance: HBM > 1KV; MM > 200V; CDM > 1KV.

The M74HC175M1R is available in a SO16 package, making it suitable for surface-mount technology (SMT) applications. This component is ideal for use in registers, counters, and control circuits, offering a reliable solution for designers seeking a balance between power efficiency and performance.

STMicroelectronics provides detailed datasheets and technical documentation to support the integration of the M74HC175M1R into various electronic projects, ensuring that engineers can utilize this flip-flop to its full potential.
