Nexperia USA Inc. 74HCT4075PW,112

Overview

74HCT4075PW,112 from Nexperia is a triple 3-input OR gate logic IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V), 14-pin SO14 (SOT108-1) package, propagation delay of 12 ns typical at 4.5 V/50 pF, and operation across -40 °C to +125 °C for industrial control signal routing.

For engineers reviewing the 74HCT4075PW,112 datasheet, 74HCT4075PW,112 pinout, 74HCT4075PW,112 application, or 74HCT4075PW,112 equivalent, this device serves as a robust, temperature-stable combinational logic element for bus arbitration, enable gating, and status aggregation in mixed-voltage digital systems where TTL-level interfacing is required.

Technical Context

The 74HCT4075PW,112 implements three independent OR gates, each accepting three inputs (nA, nB, nC) and producing one active-high output (nY). Its TTL-compatible input stage ensures reliable interfacing with legacy 5 V logic families while maintaining CMOS power efficiency.

Each gate operates with rail-to-rail output swing (VOH ≥ 3.98 V, VOL ≤ 0.26 V at IO = ±4 mA), supports input clamping diodes for overvoltage tolerance, and exhibits low static current (ICC ≤ 40 μA at 125 °C) and input capacitance (CI = 3.5 pF), enabling high-speed, low-noise signal combining in noise-sensitive environments.

FAQ

Is 74HCT4075PW,112 pin-compatible with 74HC4075 variants?

Yes - both share identical SO14 (SOT108-1) pinout and terminal assignments. However, 74HC4075 uses CMOS input thresholds (VIH = 3.15 V min at 4.5 V), so direct substitution requires verification of driving source compatibility to avoid marginal logic levels.

Can 74HCT4075PW,112 operate at 3.3 V supply?

No - the 74HCT4075 is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds become undefined and output drive degrades significantly; use 74LVC4075 or 74AUP4075 for 3.3 V systems.

What is the maximum capacitive load this device can drive reliably?

The datasheet specifies timing and drive capability up to 50 pF. While it can physically drive >100 pF, propagation delay increases nonlinearly beyond 50 pF (e.g., +15 ns at 100 pF), so maintain ≤50 pF for guaranteed 12 ns performance in timing-critical paths.

Does 74HCT4075PW,112 support hot insertion or live insertion?

No - it lacks hot-swap protection circuitry. Applying VCC before inputs or vice versa may cause latch-up due to internal parasitic SCR structures. Power sequencing must follow VCC-first, then inputs, then outputs to ensure safe operation.
