74HCT1G00GW,125

Overview

The Nexperia 74HCT1G00GW,125 is a single 2-input NAND gate in the 74HCT logic series. 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 utilizes a TSSOP5 (SOT353-1) package with five leads and a body width of 1.25 mm. Static characteristics include a maximum input leakage current of 1.0 µA at 5.5 V and a maximum supply current of 20 µA. Dynamic performance specifies a propagation delay of up to 27 ns at 4.5 V with 50 pF load capacitance.

Feature Summary

• Accepts TTL-level inputs for direct interfacing with Transistor-Transistor Logic systems
• Includes internal clamp diodes on inputs to allow connection to voltages exceeding VCC using current limiting resistors
• Provides high noise immunity and symmetrical output impedance characteristics

Applications

• General-purpose digital logic signal processing
• Interface circuits requiring TTL-to-CMOS level translation
• Signal gating and boolean logic operations in embedded systems

Procurement Notes

Verify that the component matches the specific HCT logic family requirements rather than standard HC or AHCT variants. Confirm the SOT353-1 package designation aligns with PCB footprint constraints. Ensure the operating environment remains within the specified -40 °C to +125 °C thermal limits during system integration.

Selection Notes

Select this component when TTL-compatible input thresholds are required alongside CMOS low power dissipation. The single-gate configuration minimizes board space compared to multi-gate packages. Verify that the 4.5 V to 5.5 V supply voltage range meets the target system power specifications before finalizing the design.

Part Context

This part belongs to the Nexperia 74HCT1Gxx series of single-function logic gates. It shares the same logical function as the 74HC1G00 but differs in input threshold levels to support TTL compatibility. The 'GW' suffix indicates the TSSOP5 plastic thin shrink small outline package variant.

Replacement Considerations

The 74HCT1G00GV,125 serves as a functional substitute utilizing the SC-74A (SOT753) package.
