Overview
The Nexperia 74HC1G14GV,125 is a single inverter with Schmitt-trigger input housed in an SC-74A (SOT753) package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. Propagation delay ranges from 32 ns at 6.0 V to 190 ns at 2.0 V with a 50 pF load. The device features CMOS low power dissipation, unlimited input rise/fall times, and ESD protection exceeding 2000 V (HBM).
Feature Summary
- Schmitt-trigger inputs transform slowly changing signals into sharply defined output waveforms.
- Inputs include clamp diodes for interfacing with voltages exceeding VCC using current limiting resistors.
- High noise immunity and symmetrical output impedance ensure reliable signal inversion.
Applications
- Wave and pulse shapers
- Astable multivibrators
- Monostable multivibrators
Procurement Notes
Verify the specific ordering suffix '125' against the manufacturer's official documentation to confirm packaging details such as reel or cut tape specifications. Ensure the component meets RoHS compliance requirements relevant to your manufacturing process. Cross-reference the datasheet revision date to confirm the validity of electrical characteristics before finalizing design integration.
Selection Notes
Select this component when a single-channel inverter with hysteresis is required for noisy environments. The wide supply voltage range allows compatibility with various logic families. Verify that the propagation delay at your operating voltage meets timing constraints. Consider the thermal derating curves if operating near maximum temperature limits.
Part Context
This part belongs to the 74HC series of high-speed CMOS logic devices. It is functionally similar to the 74HCT1G14 but utilizes CMOS input switching levels rather than TTL levels. The GV suffix indicates the SC-74A surface-mount package. It serves as a fundamental building block for digital signal conditioning and timing circuits.
Replacement Considerations
The 74HCT1G14GV,125 is a direct functional replacement with TTL-compatible input thresholds. Other single-inverter Schmitt trigger variants from different manufacturers may require verification of pinout compatibility and voltage level matching.
FAQ
How does the Schmitt-trigger input benefit signal processing?
It eliminates jitter by converting slowly changing input signals into sharply defined output signals, making it suitable for noisy environments.
Can this device interface with voltages higher than VCC?
Yes, the inputs include clamp diodes, allowing the use of current-limiting resistors to interface with voltages exceeding the supply voltage.
