74HC2G14GW-Q100H

Overview

The Nexperia 74HC2G14GW-Q100H is a dual inverting Schmitt trigger IC from the 74HC logic family, housed in a TSSOP6 (SOT363-2) surface-mount package with six leads. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range of -40 °C to +125 °C. The device features CMOS input levels, balanced propagation delays, and unlimited input rise/fall times. Static characteristics include a maximum low-level output current of 5.2 mA and a high-level output current of -5.2 mA at 6.0 V. Dynamic performance specifies a maximum propagation delay of 190 ns at 2.0 V and 32 ns at 6.0 V under a 50 pF load.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1 standards
• Schmitt trigger inputs transform slowly changing signals into sharply defined jitter-free outputs
• High noise immunity with balanced propagation delays and unlimited input rise and fall times
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

Applications

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

Procurement Notes

Verify the specific ordering suffix '125' against the manufacturer's official documentation to confirm tape-and-reel packaging details. Ensure the component matches the SOT363-2 package outline dimensions provided in the datasheet. Confirm that the automotive grade designation aligns with project requirements before finalizing procurement orders.

Selection Notes

Select this component when dual inverting functions with Schmitt trigger hysteresis are required in space-constrained designs. The wide supply voltage range accommodates various system power rails. Verify that the operating temperature range meets environmental specifications. Consider the package footprint compatibility during PCB layout planning.

Part Context

This part belongs to the Nexperia 74HC2G14-Q100 series, which includes variants like the 74HCT2G14GW-Q100H. The HC variant utilizes CMOS input levels, whereas the HCT version supports TTL levels. Both share identical pin configurations and automotive qualifications but differ in input threshold voltages and recommended operating conditions.

Replacement Considerations

The 74HCT2G14GW-Q100H serves as a functional substitute with compatible pinouts but requires a 4.5 V to 5.5 V supply range due to TTL input levels. Verify that the application circuitry supports these specific voltage constraints before implementing any cross-family replacements.
