74HCT2G17GW/C125

Overview

The 74HCT2G17GW/C125 is a dual non-inverting Schmitt trigger manufactured by Nexperia, distributed under the NXP USA Inc. brand. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL input levels and includes clamp diodes on its inputs. In the SOT363-2 (TSSOP6) package, it provides two independent channels with balanced propagation delays.

Feature Summary

• Schmitt-trigger inputs transform slowly changing signals into sharply defined jitter-free output signals
• Inputs include clamp diodes enabling interface to voltages exceeding VCC using current limiting resistors
• High noise immunity and CMOS low power dissipation characteristics

Applications

• Wave and pulse shaping for highly noisy environments
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify that the component matches the specific HCT logic family requirements, as this variant differs electrically from the HC version. Confirm the ordering suffix indicates the correct temperature grade and packaging configuration. Ensure the source documentation aligns with the requested manufacturer branding and part number designation before finalizing procurement specifications.

Selection Notes

Select this component when TTL-compatible input thresholds are required alongside Schmitt trigger functionality. It is suitable for applications needing signal conditioning in noisy environments where slow input transitions must be converted to clean digital outputs. Verify that the operating voltage remains within the specified 4.5 V to 5.5 V range for proper performance.

Part Context

This component belongs to the 74HC/HCT2G17 series of dual buffers with Schmitt-trigger inputs. It is part of a broader family of small-outline packages designed for surface-mount applications. The datasheet covers both HC and HCT variants, with the HCT version specifically optimized for 5 V TTL logic compatibility while maintaining CMOS input characteristics.

Replacement Considerations

The 74HC2G17GW serves as a functional substitute if CMOS input levels are acceptable instead of TTL levels. Other dual Schmitt triggers in similar packages may require verification of pinout compatibility and electrical parameter alignment.
