Nexperia USA Inc. 74AHC04PW,112

Overview

74AHC04PW,112 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, featuring 3.0 ns typical propagation delay at 5 V/15 pF, and rated for -40 °C to +125 °C ambient temperature. It serves as a level-shifting signal conditioner in digital logic interfacing between mixed-voltage subsystems.

For engineers reviewing the 74AHC04PW,112 datasheet, 74AHC04PW,112 pinout, 74AHC04PW,112 application, or 74AHC04PW,112 equivalent, this device is selected for low-power, high-noise-immunity inversion in industrial control I/O expansion, microcontroller peripheral buffering, and clock signal conditioning where balanced tPLH/tPHL and TTL/CMOS input compatibility are required.

Technical Context

The 74AHC04PW,112 implements six independent unbuffered CMOS inverters with rail-to-rail output swing and symmetrical propagation delays (tPLH ≈ tPHL). Its inputs accept voltages up to 7.0 V independent of VCC, enabling robust level translation across 3.3 V and 5 V domains.

It complies with JEDEC Standard No. 7-A and supports operation across full industrial and extended temperature ranges (-40 °C to +125 °C), with static input thresholds defined at VIH = 3.85 V (min) and VIL = 1.65 V (max) at VCC = 5.5 V, ensuring reliable noise margins in noisy environments.

FAQ

Is the 74AHC04PW,112 compatible with 3.3 V and 5 V logic systems simultaneously?

Yes - its inputs tolerate up to 7.0 V regardless of VCC, allowing direct connection of 5 V signals into a 3.3 V-powered device. Outputs swing rail-to-rail, so a 3.3 V VCC yields 0–3.3 V outputs compatible with downstream 3.3 V receivers. This enables seamless bidirectional level translation without external components.

What is the maximum capacitive load the 74AHC04PW,112 can drive while maintaining specified propagation delay?

The datasheet specifies tpd at CL = 15 pF and CL = 50 pF loads. At 5.0 V supply, tpd remains within spec (≤5.5 ns typ) up to 15 pF; at 50 pF, tpd increases to ≤7.5 ns. For reliable timing closure beyond 50 pF, add series termination or reduce trace length - the device is not characterized for >50 pF loads.

Does the 74AHC04PW,112 require external pull-up or pull-down resistors on unused inputs?

No - unused inputs must be tied HIGH or LOW to prevent floating states that cause increased ICC and potential oscillation. The device has no internal pull-ups; leaving inputs unconnected violates recommended operating conditions and risks erratic behavior or excessive power draw due to metastable input voltage.

How does the thermal performance of the TSSOP14 package compare to SO14 for continuous operation at 125 °C ambient?

The SOT402-1 (TSSOP14) package derates total power linearly at 7.3 mW/K above 81 °C ambient, reaching ~210 mW at 125 °C. In contrast, the SO14 (SOT108-1) derates at 10.1 mW/K above 100 °C, yielding ~250 mW at 125 °C. Thus, SO14 supports ~19% higher power at max ambient, but TSSOP offers superior board-level thermal conduction via exposed pad variants (not applicable to this part).
