Nexperia USA Inc. 74HC4075D,653

Overview

74HC4075D,653 from Nexperia is a triple 3-input OR gate in SO14 (SOT108-1) package, operating at 2.0–6.0 V supply, with propagation delay as low as 8 ns at VCC = 6.0 V and CL = 50 pF, CMOS-level input compatibility, and guaranteed operation from -40 °C to +125 °C - used for combinational logic synthesis in industrial control sequencers and digital signal routing.

For engineers reviewing the 74HC4075D,653 datasheet, 74HC4075D,653 pinout, 74HC4075D,653 application, or 74HC4075D,653 equivalent, key selection criteria include input voltage thresholds (VIH = 1.5 V min at VCC = 2.0 V), output drive capability (±4.0 mA at VCC = 4.5 V), thermal derating above 100 °C, and compatibility with 3.3 V/5 V mixed-signal interface domains.

Technical Context

This device implements three independent 3-input OR logic functions using standard CMOS silicon technology. Each gate features input clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used. The logic function follows strict Boolean OR behavior: output is HIGH if ≥1 input is HIGH.

It operates across two compatible families: 74HC4075 (CMOS input thresholds) and 74HCT4075 (TTL-compatible inputs). This part is the HC variant, requiring VIH ≥ 1.5 V at VCC = 2.0 V and offering rail-to-rail output swing with VOH ≥ 1.9 V and VOL ≤ 0.1 V under specified loads.

FAQ

What is the maximum clock frequency supported by the 74HC4075D,653?

The 74HC4075D,653 is a combinational logic gate, not a clocked device, so it has no inherent clock frequency limit. Its usable toggle rate depends on propagation delay and load capacitance: with tpd = 8 ns (typical at VCC = 6.0 V, CL = 50 pF), the maximum reliable data rate is approximately 62.5 MHz for clean pulse transmission. System-level timing must account for worst-case delays up to 30 ns at VCC = 2.0 V.

Can the 74HC4075D,653 drive an LED directly?

No - the 74HC4075D,653 is not rated for direct LED drive. Its absolute maximum output current is ±25 mA, but recommended steady-state drive is ±4.0 mA at VCC = 4.5 V. Driving an LED typically requires 5–20 mA continuously, risking excessive junction heating and violating recommended operating conditions. Use a dedicated driver transistor or buffer stage instead.

Is the 74HC4075D,653 pin-compatible with the 74LS4075?

Yes - the 74HC4075D,653 uses the industry-standard SO14 pinout matching the 74LS4075, including identical assignment of inputs (1A–3C), outputs (1Y–3Y), VCC (pin 14), and GND (pin 7). However, electrical compatibility requires attention: LS inputs draw significant current and expect TTL thresholds, whereas HC inputs are high-impedance CMOS. Direct replacement may cause incorrect logic levels unless driven by compatible sources.

Does the 74HC4075D,653 support mixed-voltage operation (e.g., 3.3 V inputs with 5 V supply)?

Yes - the integrated input clamp diodes allow safe interface of inputs to voltages exceeding VCC when used with appropriate current-limiting resistors. For example, a 3.3 V logic signal can drive a 5 V-supplied 74HC4075D,653 input via a 1 kΩ series resistor, limiting clamp current to <1 mA. This feature enables robust level translation without external components, provided VI < VCC + 0.5 V and IIK limits (±20 mA) are respected.
