Product details
Overview
74HCT11D,652 from Nexperia is a triple 3-input AND gate logic IC operating at 4.5 V to 5.5 V supply, delivering TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), propagation delay of 16–36 ns (VCC = 4.5 V), and output drive capability of ±4.0 mA, used in digital control signal conditioning and bus gating in industrial PLC I/O modules.
For engineers reviewing the 74HCT11D,652 datasheet, 74HCT11D,652 pinout, 74HCT11D,652 application, or 74HCT11D,652 equivalent, key selection criteria include TTL-level input compatibility, SO14 package thermal derating (10.1 mW/K above 100 °C), guaranteed operation from –40 °C to +125 °C, and static current draw under 40 μA at max temperature.
Technical Context
This device implements three independent AND gates with diode-clamped inputs enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Each gate performs standard Boolean AND logic: output high only when all three inputs are high.
It operates within JEDEC-compliant voltage ranges (JESD7A, JESD8C), supports HBM ESD protection >2000 V and CDM >1000 V, and maintains specified VOH/VOL across –40 °C to +125 °C with VIH/VIL thresholds fixed for TTL compatibility - not CMOS-ratio dependent.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple 3-input AND gate; each gate outputs HIGH only if all three inputs are HIGH |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with 5 V TTL systems and stable noise margins |
| Propagation Delay | 16–36 ns at VCC = 4.5 V, CL = 50 pF - defines maximum clock/data rate for combinational logic paths |
| Output Drive | ±4.0 mA - sufficient to drive standard TTL loads or multiple 74-series inputs without buffering |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees reliable recognition of legacy TTL logic levels |
| Operating Temperature | –40 °C to +125 °C - validated for under-hood automotive control modules and industrial motor drives |
| Power Dissipation | Max 500 mW (SO14); derates linearly at 10.1 mW/K above 100 °C - constrains PCB thermal design in sealed enclosures |
Pinout & Package
74HCT11D,652 is housed in a plastic small outline package (SO14) per SOT108-1, 14-pin, 3.9 mm body width, with gull-wing leads and pin 1 index marker.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Data input (Gate 1–3 A) | First input per AND gate; clamped to protect against overvoltage transients |
| 1B, 2B, 3B | Data input (Gate 1–3 B) | Second input per gate; shares same clamp diode structure as A/C pins |
| 1C, 2C, 3C | Data input (Gate 1–3 C) | Third input per gate; enables full 3-input Boolean conjunction per channel |
| 1Y, 2Y, 3Y | Data output (Gate 1–3 Y) | Open-drain compatible push-pull output; sinks or sources up to 4 mA |
| VCC | Supply voltage | Positive rail connection; must be decoupled locally with 100 nF ceramic capacitor |
| GND | Ground reference | 0 V return path; requires low-impedance connection to minimize switching noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level input compatibility | Ensures direct interface with legacy 5 V microcontrollers and peripheral ICs without level-shifting |
| Input clamp diodes | Allow safe connection to signals up to VCC + 0.5 V using external current-limiting resistors |
| High noise immunity | Guaranteed 0.4 V noise margin at VCC = 5 V due to tightly specified VIH/VIL thresholds |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient faults |
| Wide temperature range | Validated operation from –40 °C to +125 °C supports deployment in engine control units and power converters |
Applications
| Industrial PLC I/O Conditioning | Automotive Engine Control Unit (ECU) |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT11DR | TI part in SOIC-14; identical VIH/VIL, but tpd = 19–33 ns (VCC = 4.5 V) - ~15% slower typical propagation | Same industrial temp range; lower CPD (15 pF vs 20 pF) reduces dynamic power at high toggle rates | Select for cost-sensitive designs where 3–5 ns timing margin is acceptable and TI supply chain preference applies |
| 74LVC11PW,118 | Nexperia LVC variant in TSSOP-14; 1.65–5.5 V supply, VIH = 0.7×VCC - incompatible with fixed TTL thresholds | Supports mixed-voltage systems (1.8/3.3/5 V), but requires level-aware system design; not drop-in for TTL interfaces | Select only when migrating to scalable voltage domains; avoid in legacy 5 V-only systems requiring strict TTL compatibility |
Compared with SN74HCT11DR, 74HCT11D,652 offers faster propagation and higher noise immunity; versus 74LVC11PW,118, it provides guaranteed TTL-level recognition without supply-voltage dependency - critical for retrofitting into existing 5 V control boards.

FAQ
Is 74HCT11D,652 pin-compatible with 74HC11D?
Yes - both share identical SO14 pinout (SOT108-1), same terminal functions, and mechanical footprint. However, 74HCT11D uses TTL input thresholds (VIH ≥ 2.0 V), while 74HC11D uses CMOS thresholds (VIH ≥ 3.15 V at VCC = 4.5 V), so direct substitution requires verification of driving source logic levels.
What is the maximum recommended capacitive load for 74HCT11D,652 outputs?
The datasheet specifies dynamic characteristics up to 50 pF load capacitance. Driving >50 pF increases propagation delay nonlinearly and may cause ringing; for >100 pF loads, add a series resistor (22–47 Ω) near the output to dampen reflections and maintain signal integrity.
Can 74HCT11D,652 operate at 3.3 V supply?
No - the 74HCT11D variant is specified only for 4.5 V to 5.5 V operation. At 3.3 V, VIH minimum (2.0 V) remains valid, but VOH drops below TTL HIGH threshold requirements and ICC increases disproportionately; use 74LVC11 for 3.3 V systems.
Does 74HCT11D,652 require external pull-up or pull-down resistors on unused inputs?
Unused inputs must be tied to VCC or GND - floating inputs cause increased ICC, unpredictable output states, and potential oscillation. For unused gates, connect all three inputs to VCC (to force HIGH output) or GND (to force LOW), then leave output unconnected or tie to GND via 10 kΩ if noise-sensitive.
