Nexperia USA Inc. 74AHC04D,118

Overview

74AHC04D,118 from Nexperia is a high-speed Si-gate CMOS hex inverter IC with six independent inverting buffers, pin-compatible with LSTTL, specified per JEDEC 7-A, operating from -40 °C to +125 °C, and featuring CMOS-level inputs (VIH = 3.85 V at VCC = 5.5 V), 5.5 V absolute max supply, and 3.0 ns typical propagation delay at VCC = 5.0 V with 15 pF load.

For engineers reviewing the 74AHC04D,118 datasheet, 74AHC04D,118 pinout, 74AHC04D,118 application, or 74AHC04D,118 equivalent, this device is selected for level-shifting, signal inversion, and waveform shaping in industrial control logic, microcontroller I/O buffering, and mixed-voltage interface circuits where balanced propagation delays and TTL-compatible drive capability are required.

Technical Context

The 74AHC04D,118 implements six independent CMOS inverter stages using silicon-gate technology, each with symmetrical input thresholds and rail-to-rail output swing. Its input structure accepts voltages up to 7.0 V regardless of VCC, enabling robust interfacing across voltage domains.

It operates under JEDEC-standardized conditions with guaranteed performance over -40 °C to +125 °C, supports 15–50 pF capacitive loads, and delivers 8 mA sink/source drive strength while maintaining sub-7 ns max propagation delay at 5.0 V and 50 pF - critical for timing-critical digital signal conditioning.

FAQ

Is 74AHC04D,118 compatible with 5 V TTL logic outputs?

Yes - its inputs tolerate up to 7.0 V and VIH is specified at 3.85 V min when VCC = 5.5 V, allowing direct connection to standard 5 V TTL outputs without level shifting. However, for guaranteed compatibility with marginal TTL high-level voltages (<3.5 V), 74AHCT04D,118 (TTL-input variant) is preferred.

What is the maximum capacitive load the 74AHC04D,118 can drive reliably?

The device is characterized up to 50 pF load capacitance, with tpd remaining within specification (≤7.0 ns max at VCC = 5.0 V). For loads exceeding 50 pF, propagation delay increases linearly and output rise/fall times degrade; use a buffer stage or reduce trace length and stubs to maintain signal integrity.

Does 74AHC04D,118 require external pull-up or pull-down resistors on unused inputs?

No - unused inputs must be tied to VCC or GND to prevent floating states and increased ICC. The device has no internal termination; leaving inputs unconnected risks oscillation, excess power consumption, and ESD susceptibility due to undefined gate voltage.

Can 74AHC04D,118 operate at 2.5 V supply?

Yes - the recommended operating range starts at 2.0 V. At VCC = 2.5 V, VIH is 1.8 V min and VOL is ≤0.36 V max at 4 mA load, supporting interoperability with 2.5 V logic families. Propagation delay increases to ~9.5 ns max (CL = 50 pF), which remains suitable for non-critical timing paths.
