Nexperia USA Inc. 74AHC04PW,118

Overview

74AHC04PW,118 from Nexperia is a high-speed Si-gate CMOS hex inverter with six independent inverting buffers, pin-compatible with LSTTL, operating from 2.0 V to 5.5 V supply, delivering propagation delays as low as 3.0 ns (VCC = 5.0 V, CL = 15 pF), and rated for -40 °C to +125 °C ambient temperature - used in digital logic level translation, clock signal inversion, and bus driving in industrial control systems.

For engineers reviewing the 74AHC04PW,118 datasheet, 74AHC04PW,118 pinout, 74AHC04PW,118 application, or 74AHC04PW,118 equivalent, key selection criteria include CMOS-level input compatibility, balanced tPLH/tPHL timing, TSSOP14 thermal performance, and static drive capability of ±8 mA at VCC = 4.5 V.

Technical Context

This device implements six independent CMOS inverter stages with rail-to-rail output swing and TTL-compatible input thresholds only in the AHCT variant - the AHC version accepts inputs up to VCC + 0.5 V, enabling mixed-voltage interfacing. Input clamping diodes support ESD robustness per HBM >2000 V and CDM >1000 V.

Propagation delay is tightly controlled across voltage and temperature: at VCC = 3.3 V and CL = 15 pF, typical tpd is 4.0 ns with max 8.5 ns over -40 °C to +125 °C; dynamic power dissipation is governed by CPD = 13.5 pF, enabling low-noise switching in high-density PCB layouts.

FAQ

What is the maximum recommended input voltage for 74AHC04PW,118?

The absolute maximum input voltage is VCC + 0.5 V, per Table 4 limiting values. At VCC = 5.5 V, inputs may safely reach 6.0 V. This overvoltage tolerance enables direct interfacing with higher-voltage logic families without external clamping diodes, provided input current remains within ±20 mA limits.

Can 74AHC04PW,118 operate reliably at 3.3 V supply?

Yes - the 74AHC04PW,118 is fully specified from 2.0 V to 5.5 V. At VCC = 3.3 V ±0.3 V, it delivers typical propagation delay of 4.0 ns (CL = 15 pF) and guaranteed VOH ≥ 2.58 V / VOL ≤ 0.36 V under 4 mA load, meeting standard 3.3 V LVTTL and LVCMOS interface requirements.

Is the exposed pad on the TSSOP14 package electrically connected?

No - the thermal pad on SOT402-1 (TSSOP14) is not electrically connected. Per section 5.1, it has no electrical or mechanical requirement to be soldered; if soldered, it must remain floating or tied to GND. It serves only thermal conduction, not signal or power routing.

How does 74AHC04PW,118 differ from 74HC04 in practical design?

The 74AHC04PW,118 offers significantly faster propagation (3.0 ns vs ~15 ns at 5 V), lower ICC (2.0 μA vs ~2 μA but with tighter max spec), and enhanced ESD protection (HBM >2000 V vs ~2000 V). Its input structure also accepts voltages beyond VCC, unlike standard 74HC, enabling safer mixed-voltage node interfacing without added protection circuitry.
