Overview
The Nexperia 74AHCT2G08GD,125 is a dual 2-input AND gate in the AHCT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input levels. The device provides two independent AND gates with overvoltage tolerant inputs up to 5.5 V. Propagation delay is specified at 6.2 ns maximum (CL=15 pF) and 7.9 ns maximum (CL=50 pF) at 5.0 V. Input leakage current is limited to 2.0 μA maximum across the operating temperature range of -40 °C to +125 °C.
Feature Summary
- Dual 2-input AND gate configuration
- TTL compatible input switching levels
- Overvoltage tolerant inputs up to 5.5 V
- Balanced propagation delays
Applications
- Mixed voltage environment translation
- Digital signal processing logic gating
- General purpose logic applications
Procurement Notes
Verify the specific ordering suffix GD against the manufacturer's current product data sheet to confirm package type and availability. Confirm RoHS compliance status and environmental declarations directly from official documentation before procurement. Ensure the component matches the required temperature range and electrical specifications for the intended application design.
Selection Notes
Select this component when TTL-level interface compatibility is required within a 5 V system. The AHCT series ensures CMOS performance with TTL input thresholds. Verify that the 5.5 V input tolerance aligns with the source signal levels. Consider the SOT996-2 package dimensions for PCB layout constraints.
Part Context
This part belongs to the Nexperia 74AHC(AHCT)2Gxx single-function logic family. These devices are designed for high-speed digital applications requiring low power consumption. The AHCT variant specifically targets systems interfacing with legacy TTL logic standards while maintaining modern CMOS electrical characteristics.
Replacement Considerations
Check for direct substitutes such as the 74AHCT2G08DC or 74AHCT2G08DP if the GD package is unavailable. Verify pinout compatibility and electrical parameter equivalence before substitution.
