Overview
The CD74HCT175M is a high-speed CMOS logic quad D-type flip-flop manufactured by Texas Instruments. It features four independent D-type flip-flops with a common clock and asynchronous reset, housed in a 16-pin SOIC package. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 20 MHz. It functions reliably across an extended temperature range from -55°C to +125°C.
Feature Summary
- Integrates four independent D-type flip-flops with a shared clock input for synchronized data storage.
- Includes an asynchronous reset function to clear all outputs independently of the clock signal.
- Utilizes silicon gate CMOS technology to achieve LSTTL-compatible switching speeds with low power consumption.
Applications
- Data storage registers in digital systems
- Shift register configurations
- State machine implementations
Procurement Notes
Verify the specific suffix 'M' corresponds to the SOIC-16 surface-mount package variant rather than the DIP version. Confirm RoHS compliance status and check for lead-free certification details on the official datasheet before finalizing procurement specifications.
Selection Notes
Select this component when a quad D-type flip-flop with asynchronous reset is required in a surface-mount design. Ensure the system voltage remains within the 4.5V to 5.5V range and that the operating environment falls within the specified industrial temperature limits for reliable performance.
Part Context
This part belongs to the Texas Instruments 74HCT series, which provides CMOS logic compatible with LSTTL interfaces. The CD74HCT175M specifically addresses applications requiring multiple synchronized data storage elements in a compact surface-mount footprint, distinguishing it from through-hole variants like the EE4.
