74HCT2G14GV,125

Overview

The Nexperia 74HCT2G14GV,125 is a dual inverting Schmitt trigger integrated circuit belonging to the HCT logic family. 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. It is housed in a SC-74 (TSOP6) plastic surface-mounted package with six leads, designated as SOT457.

Feature Summary

• Dual inverter configuration with Schmitt-trigger inputs for noise immunity
• TTL-compatible input levels for direct interfacing with TTL systems
• Input clamp diodes enable current limiting resistor usage for voltages exceeding VCC
• Balanced propagation delays and unlimited input rise/fall times

Applications

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

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when a dual inverter with Schmitt-trigger inputs is required for noisy signal environments. Ensure the design utilizes a 4.5 V to 5.5 V power supply to match the HCT logic family specifications. Confirm that the SC-74 package footprint aligns with the PCB layout requirements.

Part Context

This part belongs to the Nexperia 74HCT2G14 series, which also includes variants like the 74HC2G14 and different package options such as TSSOP6. The GV suffix specifically denotes the SC-74 (TSOP6) package type. Other members of the family may offer HC logic levels or alternative packaging solutions depending on specific design constraints.

Replacement Considerations

Direct replacements include other 74HCT2G14 variants with compatible packages, such as the 74HCT2G14GW in a TSSOP6 package. Cross-family alternatives like the 74HC2G14 series are available but require verification of input level compatibility.
