74AHC1G32GW,125

Overview

The Nexperia 74AHC1G32GW,125 is a single 2-input OR gate in the 74AHC logic family. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device utilizes a TSSOP5 (SOT353-1) package with five leads and a body width of 1.25 mm. Static characteristics include an input leakage current maximum of 2.0 μA at -40 °C to +125 °C and a supply current maximum of 40 μA at VCC = 5.5 V. Dynamic performance specifies a propagation delay maximum of 10.0 ns at VCC = 3.0 V to 3.6 V with CL = 50 pF across the full temperature range.

Feature Summary

• Overvoltage tolerant inputs allow operation in mixed voltage environments without level shifting components.
• CMOS low power dissipation design ensures minimal static current consumption during standby states.
• High noise immunity and symmetrical output impedance provide balanced signal integrity for digital applications.

Applications

• Signal translation between different voltage domains
• Digital logic implementation in portable devices
• General purpose OR gate functions in embedded systems

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as GW denotes TSSOP5 while GV indicates SC-74A. Confirm RoHS compliance status and ensure the component meets the intended operating temperature range specifications. Cross-reference the manufacturer part number against official datasheets to validate authenticity before integration into production designs.

Selection Notes

Select this component when CMOS input levels are required rather than TTL thresholds found in AHCT variants. Ensure the application voltage remains within the 2.0 V to 5.5 V range to maintain specified switching speeds. Consider the TSSOP5 package dimensions for PCB layout constraints and verify that ESD protection requirements align with the HBM and CDM ratings provided in the datasheet.

Part Context

This component belongs to the 74AHC1G series of single-gate integrated circuits manufactured by Nexperia. It shares functional similarities with other members like the 74AHCT1G32 but differs in input threshold compatibility. The GW suffix specifically identifies the thin shrink small outline package variant, distinguishing it from surface-mounted packages like SC-74A or XSON5 options available within the same logical family.

Replacement Considerations

The 74AHCT1G32GW,125 serves as a direct pin-compatible alternative if TTL input levels are acceptable. Other single OR gates in the 74AHC family may require verification of package footprint and electrical parameter alignment before substitution.
