Inverter Gates Procurement Notes

Verify the specific suffix M96 against the manufacturer's official datasheet to confirm pinout compatibility and packaging dimensions. Ensure that the required operating voltage aligns with the specified 4.5 V to 5.5 V range. Confirm that the SOIC-14 package footprint matches the target PCB design constraints before finalizing procurement orders.

Inverter Gates Selection Notes

Select this component when designing circuits that require dual four-input AND functionality within a compact surface-mount form factor. The HCT series ensures TTL-compatible input thresholds while maintaining CMOS output drive capabilities. Consider the 27 ns propagation delay for timing-critical applications and verify that the 4 mA output current meets the load requirements of downstream components.

Inverter Gates Part Context

This part belongs to the Texas Instruments CD74HCT family of high-speed CMOS logic devices. The family is characterized by operation compatible with standard TTL logic levels, making it suitable for interfacing between different logic families. The CD74HCT21 specifically addresses designs needing multiple four-input AND gates without consuming excessive board space.

Inverter Gates Replacement Considerations

Check for CD74HCT21 variants with different suffixes such as E4 or G4, which may indicate lead-free or RoHS-compliant versions. Verify that alternative packages like TSSOP are electrically equivalent if space constraints differ. Consult the manufacturer's obsolescence notices to ensure long-term availability for production runs.
