Nexperia USA Inc. 74AHC2G08DP,125

Overview

74AHC2G08DP,125 from Nexperia is a dual 2-input AND gate logic IC in TSSOP8 package, operating from 2.0 V to 5.5 V supply, with overvoltage-tolerant inputs up to 5.5 V, CMOS-level input compatibility, and guaranteed operation from –40 °C to +125 °C - used for level translation and signal gating in mixed-voltage digital interfaces.

For engineers reviewing the 74AHC2G08DP,125 datasheet, 74AHC2G08DP,125 pinout, 74AHC2G08DP,125 application, or 74AHC2G08DP,125 equivalent, key selection criteria include propagation delay (≤8.0 ns at VCC = 5.0 V, CL = 15 pF), output drive strength (±8 mA), input voltage tolerance, static power consumption (≤40 μA at VCC = 5.5 V), and thermal reliability across automotive-grade temperature range.

Technical Context

This device implements two independent AND logic functions with symmetrical output impedance and balanced propagation delays between rising and falling edges. Each gate accepts two inputs (1A/1B, 2A/2B) and drives one output (1Y/2Y), with all inputs tolerant to 5.5 V regardless of VCC level - enabling direct interfacing between 3.3 V logic and 5 V subsystems without external level shifters.

It complies with JEDEC JESD78 Class II Level A latch-up immunity (>100 mA), supports HBM ESD protection >2000 V and CDM >1000 V, and maintains valid logic thresholds across its full operating temperature range (–40 °C to +125 °C) under specified supply and load conditions.

FAQ

Is 74AHC2G08DP,125 pin-compatible with 74AHCT2G08DP,125?

Yes - both share identical TSSOP8 (SOT505-2) pinout, package dimensions, and thermal characteristics. The only functional difference lies in input threshold levels: AHC uses CMOS-compatible VIH/VIL (e.g., VIH = 3.85 V at VCC = 5.5 V), while AHCT uses TTL-compatible thresholds (VIH = 2.0 V). No PCB redesign is needed for substitution.

Can 74AHC2G08DP,125 operate reliably at 2.0 V supply?

Yes - it is fully specified down to 2.0 V supply, with guaranteed VOH ≥1.5 V and VOL ≤0.5 V at IO = ±4 mA, and propagation delay ≤12.0 ns (max) at CL = 50 pF. Input thresholds scale with VCC, maintaining noise margin >30% across the entire 2.0–5.5 V range.

Does this device require external pull-up or pull-down resistors on unused inputs?

No - unused inputs may be tied directly to VCC or GND. The device has no internal weak pull-ups/pull-downs, but its CMOS inputs draw <0.1 μA leakage current, so hard-wiring ensures stable logic state without additional components or board space.

What is the maximum capacitive load this device can drive without signal degradation?

It is characterized up to 50 pF load capacitance with guaranteed timing (tpd ≤10.5 ns at VCC = 5.5 V). For loads exceeding 50 pF, propagation delay increases linearly; slew rate remains controlled due to symmetrical output impedance, but designers should verify setup/hold margins in high-fanout or long-trace scenarios using SPICE simulation.
