NXP Semiconductors 74HC4075D,652

Overview

74HC4075D,652 from Nexperia is a triple 3-input OR gate in SO14 (SOT108-1) package, operating at 2.0–6.0 V supply with CMOS-level inputs, 10 ns typical propagation delay at 4.5 V, and -40 °C to +125 °C temperature range. It implements combinational logic for bus arbitration, enable gating, and status merging in industrial control and digital interface circuits.

For engineers reviewing the 74HC4075D,652 datasheet, 74HC4075D,652 pinout, 74HC4075D,652 application, or 74HC4075D,652 equivalent, this device supports high-noise-margin logic design, input clamping for overvoltage-tolerant interfacing, and low-power static operation with <2 μA ICC at 6 V - critical for battery-backed and thermally constrained systems.

Technical Context

The 74HC4075D,652 integrates three independent 3-input OR gates on a single die, each with diode-clamped inputs enabling safe interfacing to signals exceeding VCC when used with current-limiting resistors. Its CMOS architecture ensures rail-to-rail output swing and symmetrical drive capability (±4 mA at 4.5 V).

Propagation delay is tightly specified across voltage and temperature: 10 ns (typ) at VCC = 4.5 V, 25 °C; 25 ns (max) over -40 °C to +85 °C; and 30 ns (max) up to +125 °C. Input transition rate support extends to 139 ns/V at 4.5 V, ensuring robust timing under fast-edge conditions.

FAQ

Can 74HC4075D,652 operate reliably at 3.3 V?

Yes. The 74HC4075D,652 is fully specified down to 2.0 V supply, with guaranteed VIH = 1.35 V and VOL ≤ 0.26 V at VCC = 3.3 V and IO = 4 mA. Propagation delay remains ≤ 15 ns (max) across -40 °C to +125 °C, making it suitable for 3.3 V embedded systems without level shifting.

What is the maximum capacitive load this device can drive?

The 74HC4075D,652 is characterized with CL = 50 pF in dynamic testing and supports up to 50 pF load capacitance while maintaining tpd ≤ 20 ns (max) at VCC = 4.5 V. For heavier loads (>75 pF), output rise/fall times increase linearly, and layout decoupling becomes critical to avoid ringing or false triggering.

Does this part include Schmitt-trigger inputs?

No. The 74HC4075D,652 features standard CMOS inputs without hysteresis. Its input thresholds are VIH = 3.15 V and VIL = 1.35 V at VCC = 4.5 V, giving ~1.8 V noise margin but no built-in waveform shaping. For noisy environments, external RC filtering or a dedicated Schmitt-trigger buffer (e.g., 74HC14) is recommended upstream.

Is there a lead-free and halogen-free version available?

Yes. The 74HC4075D,652 is manufactured in compliance with RoHS Directive 2011/65/EU and is both lead-free and halogen-free, with homogeneous material declarations confirming <900 ppm bromine and <900 ppm chlorine. Full compliance documentation is available upon request for IPC-1752A reporting.
