Nexperia USA Inc. 74AHC08PW,112

Overview

74AHC08PW,112 from Nexperia is a quad 2-input AND gate IC in TSSOP14 package, operating from 2.0 V to 5.5 V supply, with CMOS-level inputs, overvoltage-tolerant inputs up to 5.5 V, and specified for -40 °C to +125 °C industrial temperature range. It functions as a logic-level translator in mixed-voltage digital systems such as microcontroller I/O expansion and bus interface conditioning.

For engineers reviewing the 74AHC08PW,112 datasheet, 74AHC08PW,112 pinout, 74AHC08PW,112 application, or 74AHC08PW,112 equivalent, key selection criteria include input voltage tolerance (5.5 V), propagation delay (≤7.5 ns at 5 V/50 pF), output drive capability (±8 mA), Schmitt-trigger input hysteresis, and thermal performance in TSSOP14 (SOT402-1) packaging.

Technical Context

The 74AHC08PW,112 implements four independent 2-input AND gates using advanced CMOS technology, with all inputs featuring Schmitt-trigger action for noise immunity and hysteresis-based signal conditioning. Its overvoltage-tolerant inputs enable safe interfacing between 3.3 V and 5 V domains without level-shifting circuitry.

It operates across a wide supply range (2.0–5.5 V), supports TTL-compatible input thresholds only in the AHCT variant (not applicable here), and maintains balanced propagation delays (tPLH ≈ tPHL) with typical values of 3.0 ns (VCC = 5.0 V, CL = 15 pF) and 4.2 ns (CL = 50 pF), ensuring predictable timing in synchronous logic paths.

FAQ

What is the maximum input voltage the 74AHC08PW,112 can tolerate independently of VCC?

The 74AHC08PW,112 supports input voltages up to 5.5 V regardless of the applied VCC value, as confirmed in Table 4 (Limiting Values) and Section 1 (General Description). This overvoltage tolerance enables direct interfacing with 5 V signals even when powered from 3.3 V or 2.5 V supplies, eliminating external clamping components in mixed-voltage systems.

Does the 74AHC08PW,112 have Schmitt-trigger inputs on all four gates?

Yes, all eight inputs (1A–4B) feature Schmitt-trigger action, as explicitly stated in Section 2 (Features and benefits) and verified in Table 2 (Pin description). This provides hysteresis of approximately 300 mV at VCC = 5 V, improving noise immunity and enabling reliable operation with slow-rising or noisy signals such as mechanical switch debouncing or long-trace sensor outputs.

Can the 74AHC08PW,112 operate reliably at 2.0 V supply voltage?

Yes, the device is fully specified down to 2.0 V supply, with guaranteed VIH = 1.5 V and VIL = 0.5 V at that voltage (Table 6), and propagation delay ≤11.0 ns (Table 7). Static and dynamic parameters remain valid across the entire -40 °C to +125 °C range at 2.0 V, making it suitable for ultra-low-power battery-operated applications where supply headroom is constrained.

Is the exposed thermal pad on the TSSOP14 package electrically connected?

No, the exposed pad on the SOT402-1 (TSSOP14) package is not electrically connected to any internal node. As documented in the package outline (Fig. 7) and consistent with industry-standard TSSOP construction, it serves only as a mechanical and thermal anchor. Nexperia does not require soldering it to GND or any other net; if soldered, it must remain floating or be tied to GND with no electrical functional dependency.
