Product details
Overview
74AHCT04BQ,115 from Nexperia is a high-speed CMOS hex inverter with TTL-compatible inputs, operating from 4.5 V to 5.5 V over -40 °C to +125 °C. It provides six independent inverting buffers with balanced propagation delays (typ. 3.0 ns at VCC = 5.0 V, CL = 15 pF), 8 mA output drive, and ESD protection exceeding 2000 V HBM. It is used in digital logic level translation and signal inversion within industrial control I/O modules.
For engineers reviewing the 74AHCT04BQ,115 datasheet, 74AHCT04BQ,115 pinout, 74AHCT04BQ,115 application, or 74AHCT04BQ,115 equivalent, key selection criteria include TTL-level input compatibility, DHVQFN14 thermal performance, guaranteed operation up to +125 °C, and low static current (max 40 μA at VCC = 5.5 V).
Technical Context
The 74AHCT04BQ,115 implements six independent Schmitt-trigger–free CMOS inverters with TTL-input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V). Its output stage delivers symmetrical ±8 mA drive capability under defined load conditions.
It complies with JEDEC Std. 7-A and supports rail-to-rail output swing (VOH ≥ 3.70 V, VOL ≤ 0.55 V at IO = ±8 mA), enabling reliable interfacing with legacy TTL and mixed-voltage 5 V logic systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Hex inverter - six independent A→Y complementing gates |
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and mixed-supply systems |
| Propagation Delay | 3.0 ns (typ) / 8.5 ns (max) at VCC = 5.0 V, CL = 15 pF - enables high-speed timing-critical signal inversion |
| Output Drive | ±8 mA - sufficient to drive multiple LSTTL loads or moderate PCB trace capacitance |
| Operating Temperature | -40 °C to +125 °C - qualified for extended industrial and under-hood applications |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets IEC 61000-4-2 system-level robustness requirements |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees reliable recognition of TTL logic levels |

Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V - eliminates need for external level shifters when interfacing with legacy 5 V TTL |
| Balanced propagation delays | tPLH ≈ tPHL across all six channels - ensures deterministic timing in synchronous bus inversion or clock buffering |
| Thermally enhanced package | DHVQFN14 (SOT762-1) with 9.6 mW/K derating above 98 °C - supports sustained operation in compact, high-density industrial PCBs |
| Low static power | ICC ≤ 40 μA at VCC = 5.5 V, -40 °C to +125 °C - reduces standby power in always-on control subsystems |
| Robust ESD immunity | HBM > 2000 V, CDM > 1000 V - improves manufacturing yield and field reliability without added board-level protection |
Applications
| Industrial PLC I/O Modules | Legacy System Logic Interface |
|---|---|

IC Role / Device Role / Timing Role: Edge-sharpening inverter with low skew and minimal added jitter. Use Value: Reduces pulse-width distortion to <0.5 ns across temperature range, preserving timing fidelity in automated test systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT04PW,118 | TSSOP14 package (4.4 mm width); 7.3 mW/K thermal derating above 81 °C | Lower profile but reduced thermal mass; less suitable for sustained +125 °C operation in high-power density layouts | Select when board space is constrained and thermal load is moderate; avoid in sealed enclosures above 100 °C ambient |
| SN74AHCT04DR | Texas Instruments SOIC-14; wider body (3.9 mm); 10.1 mW/K derating above 100 °C | Higher thermal resistance than DHVQFN; requires larger copper pour for equivalent junction temperature control | Prefer when legacy SOIC footprint compatibility is required and PCB layout allows generous thermal relief |
Compared with 74AHCT04PW,118 and SN74AHCT04DR, the 74AHCT04BQ,115 offers superior thermal performance per unit area and smallest footprint, making it optimal for thermally demanding, space-constrained industrial designs where +125 °C operation is mandatory.

FAQ
Is the 74AHCT04BQ,115 pin-compatible with 74LS04?
Yes - it is fully pin-compatible with 74LS04 and other 14-pin hex inverters in SO14, TSSOP14, and DHVQFN14 packages. All six inputs (Pins 1,3,5,9,11,13) and outputs (Pins 2,4,6,8,10,12) map identically, with GND at Pin 7 and VCC at Pin 14. No PCB redesign is needed for migration.
Can the exposed thermal pad on the DHVQFN14 package be left floating?
Yes - the exposed pad (terminal 1 index area) has no electrical function and may remain unsoldered. If soldered, it must be either left electrically floating or connected to GND; connecting to any other net violates the device's thermal and ESD design intent and may impair reliability.
What is the maximum capacitive load this device can drive reliably?
The device is characterized up to 50 pF (tPD max = 10.0 ns at VCC = 5.0 V). Driving >50 pF increases propagation delay nonlinearly and may cause output rise/fall time degradation. For loads >50 pF, add a series resistor (22–47 Ω) near the output to dampen ringing and maintain signal integrity.
Does this part support partial power-down or I/O retention when VCC = 0 V?
No - the 74AHCT04BQ,115 lacks I/O protection diodes rated for input voltages exceeding VCC, and its inputs are not 5 V tolerant when unpowered. Applying input signals with VCC = 0 V risks forward-biasing internal clamps and damaging the device. Always power VCC before asserting inputs.
