74HCT2G17GV,125

Overview

The Nexperia 74HCT2G17GV,125 is a dual non-inverting Schmitt trigger buffer housed in an SC-74 (TSOP6) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports temperatures from -40 °C to +125 °C. The device features TTL-level inputs, balanced propagation delays, and unlimited input rise/fall times. Static characteristics include low power dissipation and high noise immunity. Dynamic performance at 4.5 V with 50 pF load shows a maximum propagation delay of 45 ns and transition time of 22 ns.

Feature Summary

• Dual non-inverting buffers with Schmitt-trigger inputs for jitter-free output signals
• TTL-compatible input levels ensuring compatibility with standard logic families
• High noise immunity suitable for operation in highly noisy environments

Applications

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

Procurement Notes

Verify the specific ordering suffix '125' corresponds to the required tape and reel packaging configuration. Confirm that the SC-74 (SOT457) package variant matches the footprint requirements of the target PCB design. Ensure the HCT logic family voltage specifications align with the system's 5 V operating environment before finalizing procurement.

Selection Notes

Select this component when interfacing slow or noisy signals requiring clean digital transitions. The HCT series ensures direct compatibility with 5 V TTL logic systems. Verify that the required propagation delay and output drive capabilities meet the circuit timing constraints. Consider the SC-74 package dimensions if space-constrained surface-mount assembly is necessary.

Part Context

This part belongs to the Nexperia 74HCT2G17 product line, which includes dual Schmitt trigger buffers. The GV suffix indicates the SC-74 (TSOP6) plastic surface-mounted package. This family provides robust signal conditioning for digital applications where input signal integrity is compromised by noise or slow edge rates.

Replacement Considerations

Direct substitutes include the 74HC2G17GV,125 for CMOS-level input compatibility.
