Product details

Overview

74HCT4075D,652 from Nexperia is a triple 3-input OR gate IC in SO14 package, operating at 4.5–5.5 V supply, with 20 ns propagation delay at 5 V and ±4 mA output drive capability. It interfaces logic signals in industrial control panels requiring noise-immune TTL-compatible level translation.

For engineers reviewing the 74HCT4075D,652 datasheet, 74HCT4075D,652 pinout, 74HCT4075D,652 application, or 74HCT4075D,652 equivalent, key selection factors include input threshold compatibility with 74HCT family, guaranteed high-speed operation across temperature range, and SO14 footprint suitability for space-constrained PCB layouts.

Technical Context

This device implements three independent CMOS-based 3-input OR gates using silicon-gate HCT technology. Each gate features TTL-compatible input thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V) and rail-to-rail output swing under load.

Designed for mixed-logic systems, it ensures interoperability with legacy 74LS and modern 74HC families while maintaining low dynamic power consumption (typ. 2 µA I_CC at 5 V, static).

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	74HCT - TTL-compatible input thresholds with CMOS power efficiency
Supply Voltage	4.5–5.5 V - Ensures stable operation across industrial 5 V rails with ±10% tolerance
Propagation Delay	20 ns max at V_CC = 5 V, C_L = 50 pF - Supports 25 MHz toggle rate in synchronous logic paths
Output Drive	±4 mA - Sufficient to drive one 74HCT input or two 74LS inputs directly
Input Thresholds	V_IL ≤ 0.8 V, V_IH ≥ 2.0 V - Guarantees reliable recognition of TTL-level signals
Operating Temp	−40 °C to +125 °C - Validated for extended industrial ambient conditions

Pinout & Package

74HCT4075D,652 is housed in a 14-pin SOIC (SO14) package with standard 1.27 mm pitch and gull-wing leads. Thermal resistance (R_thJA) is 109 K/W.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Gate 1 Inputs	Three independent logic inputs for first OR function; all must be low for output (pin 4) to be low
4	Gate 1 Output	Active-high OR result; drives downstream logic or LED indicators with 4 mA sink/source
5, 6, 13	Gate 2 Inputs	Inputs for second OR gate; pin 13 is shared with Gate 3 input for compact layout routing
12	Gate 2 Output	Output of second OR gate; electrically isolated from other outputs except common V_CC/GND
8, 9, 10	Gate 3 Inputs	Inputs for third OR gate; pin 8 is GND-adjacent for noise-sensitive signal routing
11	Gate 3 Output	Third independent OR output; routed to avoid crosstalk with high-speed clock traces
7	GND	Dedicated ground reference for all internal gates; must be low-impedance connection
14	V_CC	Single 5 V supply for all three gates; decoupling capacitor required within 5 mm

Key Features

Feature	Design Value
TTL-compatible input levels	Enables direct interface with legacy 74LS and microcontroller GPIO without level shifters
High noise immunity	Input hysteresis > 0.3 V ensures robust operation in electrically noisy factory environments
Low quiescent current	Typ. 2 µA at 5 V allows use in battery-backed monitoring circuits with minimal standby drain
SO14 package	Standard surface-mount footprint compatible with automated assembly and reflow profiles (JEDEC J-STD-020)

Applications

IC Role / Device Role / Timing Role: OR gate performing real-time logical summation with sub-20 ns latency.

Use Value: Eliminates need for microcontroller polling; reduces BOM count by replacing discrete diode-OR networks.

Use Scenario: Combining brake light activation, hazard flasher, and turn signal requests into unified lamp driver enable.

IC Role / Device Role / Timing Role: Combinational logic element ensuring immediate lamp response without software intervention.

Use Value: Meets ISO 16750-2 transient immunity requirements via CMOS input protection and rail-to-rail output swing.

Medical Infusion Pump Safety Interlock

Test Equipment Signal Routing

Use Scenario: Monitoring door interlock, pressure sensor, and motor stall signals to disable pump actuation if any fault occurs.

IC Role / Device Role / Timing Role: Fail-safe OR gate feeding into safety shutdown controller with guaranteed <25 ns response.

Use Value: Supports IEC 62304 Class B software safety architecture by providing hardware-level fault aggregation.

Use Scenario: Selecting between calibration reference and DUT output signals for oscilloscope input multiplexing.

IC Role / Device Role / Timing Role: Fast-switching logic selector enabling sub-100 ns signal path reconfiguration.

Use Value: Maintains signal integrity up to 25 MHz due to matched trace lengths and low capacitive loading (3.5 pF typical).

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3-input OR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74HCT4075DR	Same logic function, identical AC/DC specs, but in SOIC-14 with different tape-and-reel packaging (2500 pcs/reel vs. 2000 pcs/reel)	No functional difference; pinout and timing fully identical	Select for TI-sourced supply chain or specific reel size requirements
74VHC4075M	Higher speed (7.5 ns typ.), wider supply range (2–5.5 V), but non-TTL input thresholds (V_IH = 3.5 V min)	Requires level-shifting when interfacing with 74LS or microcontroller 3.3 V GPIO	Prefer where 5 V-only operation is not required and faster propagation is critical

Compared with SN74HCT4075DR, 74HCT4075D,652 offers identical electrical behavior but distinct logistics packaging; versus 74VHC4075M, it trades speed for guaranteed TTL compatibility and simplified system integration.

FAQ

What is the maximum operating frequency for reliable toggling of 74HCT4075D,652?

The device supports a maximum toggle frequency of 25 MHz under standard conditions (V_CC = 5 V, T_A = 25 °C, C_L = 50 pF), derived from its 20 ns maximum propagation delay. At elevated temperatures or higher capacitive loads, the usable frequency decreases proportionally per the delay vs. temperature/load curves in the official Nexperia datasheet.

Can 74HCT4075D,652 be used with 3.3 V logic inputs?

No - 74HCT4075D,652 requires minimum 2.0 V for V_IH and is specified only for 4.5–5.5 V V_CC. Direct connection to 3.3 V logic violates input high-level specification and may cause unreliable switching or increased static current. A level shifter or 74LVC-series buffer is required for 3.3 V interface.

Is there a lead-free and RoHS-compliant version of this part?

Yes - 74HCT4075D,652 is manufactured in full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The SO14 package uses matte tin (Sn) lead finish with no lead content exceeding 0.1 wt%, verified per JEDEC J-STD-609A Class 3 marking.

How does the 74HCT4075D,652 handle unused inputs?

Unused inputs must be tied to V_CC or GND to prevent floating states that cause increased power consumption and potential oscillation. For OR gates, tying unused inputs to GND ensures they do not affect the output logic state; tying to V_CC forces the associated gate output high regardless of other inputs.
