74AHCT1G08GW-Q100,

Overview

The Nexperia 74AHCT1G08GW-Q100,1 is a single 2-input AND gate qualified to AEC-Q100 Grade 1. 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 features TTL-level inputs and overvoltage tolerant inputs up to 5.5 V. Static characteristics include a maximum input leakage current of 2.0 μA at -40 °C to +125 °C and a maximum supply current of 40 μA. Dynamic performance specifies a propagation delay (tpd) of 10.5 ns maximum at 5.5 V with a 50 pF load. The component utilizes a TSSOP5 plastic thin shrink small outline package (SOT353-1).

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards.
• Overvoltage tolerant inputs allow operation as translators in mixed voltage environments.
• High noise immunity with symmetrical output impedance and balanced propagation delays.
• ESD protection exceeds 2000 V per HBM and 1000 V per CDM.

Applications

• Automotive electronic systems requiring robust logic gates.
• Mixed voltage environments utilizing the device as a translator.
• Wave and pulse shaping circuits.
• Astable and monostable multivibrators.

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the GW designation corresponds to the SOT353-1 (TSSOP5) form factor. Confirm that the AHCT series selection aligns with the system's requirement for TTL-compatible input levels rather than CMOS levels found in the HC series. Ensure the design accommodates the specified operating temperature range of -40 °C to +125 °C for automotive compliance.

Selection Notes

Select this component when TTL-level interface compatibility is required within an automotive-grade environment. The AHCT series ensures direct interfacing with TTL outputs while maintaining CMOS low power dissipation. Verify that the 5.5 V maximum supply voltage meets the target circuit requirements. Consider the TSSOP5 package dimensions if board space is constrained, noting the body width of 1.25 mm.

Part Context

This part belongs to the Nexperia 74AHC/AHCT1G08-Q100 family of single 2-input AND gates. The family includes variants such as the 74AHC1G08-Q100 for CMOS level inputs and other package options like SC-74A (GV) and XSON5 (GZ). All members share the same functional description and automotive qualification but differ in input voltage thresholds and physical footprint.

Replacement Considerations

The 74AHC1G08GW-Q100,1 serves as a functional alternative if CMOS input levels are acceptable instead of TTL. Other package variants within the same family, such as 74AHCT1G08GV-Q100 or 74AHCT1G08GZ-Q100, offer different mechanical footprints while retaining identical electrical specifications.
