Product details
Overview
74HCT4075PW-Q100 from Nexperia is an automotive-qualified triple 3-input OR gate in TSSOP14 package, operating from −40 °C to +125 °C with TTL-level inputs, 4.5 V–5.5 V supply range, and propagation delay of 12 ns (typ) at VCC = 4.5 V. It enables logic-level aggregation in vehicle body control modules requiring robust noise immunity and AEC-Q100 Grade 1 compliance.
For engineers reviewing the 74HCT4075PW-Q100 datasheet, 74HCT4075PW-Q100 pinout, 74HCT4075PW-Q100 application, or 74HCT4075PW-Q100 equivalent, key selection criteria include input voltage thresholds (VIH = 2.0 V min), output drive capability (±4.0 mA), ESD robustness (HBM >2000 V), and thermal derating behavior for under-hood deployment.
Technical Context
This device implements three independent CMOS-based OR gates with integrated input clamp diodes, enabling safe interfacing to signals exceeding VCC when used with current-limiting resistors. Its TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V at VCC = 4.5–5.5 V) ensure direct compatibility with legacy 5 V logic families without level translation.
Designed for automotive environments, it meets AEC-Q100 Grade 1 qualification and JEDEC JESD7A standards. Static and dynamic characteristics-including propagation delay (tpd ≤ 36 ns max at 125 °C), transition time (tt ≤ 22 ns max), and power dissipation capacitance (CPD = 32 pF)-are fully specified across the full temperature range.
Key Specifications

FAQ
What is the maximum operating temperature for the 74HCT4075PW-Q100?
The 74HCT4075PW-Q100 is qualified per AEC-Q100 Grade 1 and operates from −40 °C to +125 °C ambient temperature. This rating is validated across all electrical parameters in the datasheet, including propagation delay, output drive, and input thresholds-ensuring reliable function in under-hood environments where ambient temperatures exceed 105 °C.
Does the 74HCT4075PW-Q100 support 3.3 V logic inputs?
No, the 74HCT4075PW-Q100 has TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) and is not guaranteed to recognize 3.3 V logic HIGH levels reliably. For 3.3 V systems, use the 74HC4075PW-Q100 variant or add a level-shifting buffer. The 74HCT4075PW-Q100 requires VCC = 4.5–5.5 V to meet its specified input voltage windows.
What is the purpose of the input clamp diodes in the 74HCT4075PW-Q100?
The input clamp diodes in the 74HCT4075PW-Q100 allow safe interfacing to input signals exceeding VCC-such as sensor outputs or legacy bus voltages-when used with external current-limiting resistors. They conduct excess voltage to VCC or GND, preventing damage from overvoltage transients up to ±20 mA, as defined in the absolute maximum ratings table for the 74HCT4075PW-Q100.
Can the 74HCT4075PW-Q100 drive an LED directly?
No, the 74HCT4075PW-Q100 is not designed for direct LED driving. Its output drive capability is ±4.0 mA under specified VOH/VOL conditions-not sufficient for typical indicator LEDs requiring 5–20 mA. Using it to source/sink LED current risks violating VOL/VOH specs and degrading timing performance. For LED control, pair the 74HCT4075PW-Q100 with a dedicated driver transistor or buffer IC.
Is the 74HCT4075PW-Q100 pin-compatible with non-automotive versions like 74HCT4075PW?
Yes, the 74HCT4075PW-Q100 shares identical pinout, package (TSSOP14/SOT402-1), and electrical functionality with industrial-grade 74HCT4075PW. The "-Q100" suffix denotes AEC-Q100 qualification and extended temperature screening-but does not alter pin assignment, logic behavior, or DC/AC characteristics. Layout reuse is fully supported; only qualification documentation differs.
