74HCT1G14GV,125

Overview

The Nexperia 74HCT1G14GV,125 is a single inverter with Schmitt-trigger input housed in an SC-74A (SOT753) 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, clamp diodes for overvoltage interfacing, and high noise immunity. Static characteristics include a maximum supply current of 20 μA at 5.5 V. Dynamic performance specifies a propagation delay of up to 51 ns at 4.5 V with 50 pF load capacitance.

Feature Summary

• Schmitt-trigger input transforms slowly changing signals into sharply defined output
• TTL-compatible input levels for direct interface with TTL logic systems
• Input clamp diodes enable interfacing to voltages exceeding VCC using current limiting resistors
• High noise immunity and balanced propagation delays

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the HCT logic family aligns with the target system's voltage requirements, as it differs from HC or LVC series specifications. Ensure design compliance with the absolute maximum ratings provided in the datasheet to prevent permanent damage during operation.

Selection Notes

Select this component when TTL-level compatibility is required alongside Schmitt-trigger noise filtering. The SC-74A package offers a compact surface-mount solution suitable for space-constrained designs. Consider the propagation delay limits and power dissipation characteristics relative to the operating frequency and ambient temperature conditions.

Part Context

This part belongs to the Nexperia 74HCT1G14 series of single inverters. It shares functional similarities with the 74HC1G14 but utilizes HCT logic for TTL compatibility. The GV suffix indicates the SC-74A plastic surface-mounted package with five leads, distinguishing it from other package options like TSSOP available in the same product family.

Replacement Considerations

Direct substitutes include the 74HCT1G14GW,125 which uses a TSSOP package. Other compatible variants within the 74HCT1G14 series may be considered if package differences are acceptable.
