Nexperia USA Inc. 74AHC08PW,118

Overview

74AHC08PW,118 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, balanced propagation delays (typ. 3.0 ns at 5 V/15 pF), and specified for -40 °C to +125 °C. It serves as a logic-level translator and combinatorial gate in mixed-voltage digital control subsystems.

For engineers reviewing the 74AHC08PW,118 datasheet, 74AHC08PW,118 pinout, 74AHC08PW,118 application, or 74AHC08PW,118 equivalent, this page delivers verified pin functions, real-world timing behavior under load, thermal derating data for TSSOP14, input voltage thresholds across temperature, and validated alternatives for level-shifting and logic gating in industrial microcontroller interfaces.

Technical Context

The 74AHC08PW,118 implements four independent AND gates with Schmitt-trigger input action on all inputs, enabling noise-immune signal conditioning. Its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC, supporting bidirectional level translation between 3.3 V and 5 V domains without external components.

It operates across two distinct logic families: 74AHC08 uses CMOS-compatible input thresholds (VIH = 3.85 V min at VCC = 5.5 V), while its AHCT variant uses TTL-compatible thresholds (VIH = 2.0 V min). This part is the AHC version, requiring CMOS-level drive but offering rail-to-rail output swing and sub-10 ns propagation at 5 V.

FAQ

What is the maximum input voltage the 74AHC08PW,118 can tolerate when VCC = 3.3 V?

The 74AHC08PW,118 supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level. When powered at 3.3 V, inputs may safely accept 5 V signals without damage or clamping, enabling direct interfacing with 5 V peripherals - a key differentiator from non-AHC logic families.

Does the TSSOP14 package (SOT402-1) require soldering the exposed pad?

No - the TSSOP14 package used for 74AHC08PW,118 has no exposed thermal pad. Unlike QFN variants (e.g., SOT762-1), the SOT402-1 is a leaded package with 14 gull-wing terminals; thermal management relies on PCB copper area connected to pins 7 (GND) and 14 (VCC), with derating beginning at 81 °C.

How does propagation delay vary with load capacitance and supply voltage?

At VCC = 5.0 V, tpd is 3.0 ns (typ) with 15 pF load and 4.2 ns (typ) with 50 pF load. At VCC = 3.3 V, tpd increases to 4.0 ns (typ) at 15 pF and 5.6 ns (typ) at 50 pF. These values are measured across -40 °C to +125 °C, with worst-case max delays of 7.5 ns (5 V/50 pF) and 11.0 ns (3.3 V/50 pF).

Can the 74AHC08PW,118 be used as a level shifter between 1.8 V and 5 V domains?

No - while inputs tolerate up to 5.5 V, the device requires VCC ≥ 2.0 V to operate. Driving it from a 1.8 V source violates minimum supply specification. For 1.8 V → 5 V translation, use a dedicated level shifter (e.g., TXB0108); for 5 V → 3.3 V or 5 V → 2.5 V, the 74AHC08PW,118 is valid with VCC set to the target domain voltage.
