Overview
The DM74ALS175M is a quad D-type flip-flop manufactured by onsemi, belonging to the ALS logic series. It features four independent positive-edge-triggered D flip-flops with a common clear input in a 16-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 50 MHz. Key electrical parameters include a propagation delay of 17 ns at 5V with 50pF load, low-level output current of 8 mA, high-level output current of -400 µA, and static current of 14 mA. It functions reliably across an operating temperature range of 0°C to +70°C.
Feature Summary
- Contains four independent positive-edge-triggered D-type flip-flops with true outputs.
- Features a common direct clear input for synchronous reset functionality.
- Supports high-speed operation with a maximum clock frequency of 50 MHz.
Applications
- Parallel data storage registers
- Shift register configurations
- Timing control circuits
Procurement Notes
Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance and MSL rating prior to integration. Check for pin-compatible alternatives from Texas Instruments if supply constraints exist. Ensure soldering processes align with surface mount requirements for the SOIC-16 package.
Selection Notes
Select this component for designs requiring quad D-latch functionality within the ALS family. Consider the 17 ns propagation delay and 50 MHz limit for timing analysis. Evaluate thermal performance within the specified industrial temperature range. Compare against SN74ALS175 variants for potential cross-manufacturer compatibility.
Part Context
This part belongs to the DM74ALS series, representing Advanced Low-power Schottky TTL logic. It is produced by onsemi (formerly Fairchild Semiconductor). The device is categorized under single-function gates and flip-flops within the broader logic IC portfolio. It shares architectural similarities with other ALS devices like the DM74ALS174M.
