Product details
Overview
74HC75D-Q100 from Nexperia is a quad bistable transparent latch with complementary Q/nQ outputs, designed for automotive data latching in control and interface circuits. It features two independent enable inputs (LE12 and LE34), operates across 2.0 V to 6.0 V supply, supports -40 °C to +125 °C ambient, and delivers propagation delays as low as 10 ns at 6.0 V - used in engine control unit (ECU) input signal conditioning.
For engineers reviewing the 74HC75D-Q100 datasheet, 74HC75D-Q100 pinout, 74HC75D-Q100 application, or 74HC75D-Q100 equivalent, key selection criteria include latch enable timing (tsu = 15 ns min at 6.0 V), dual-group enable architecture, AEC-Q100 Grade 1 qualification, and SO16 package compatibility with legacy 74HC logic footprints.
Technical Context
This device implements four independent CMOS transparent latches grouped into two pairs: Latches 1–2 share LE12, while latches 3–4 share LE34. Each latch provides true and complemented outputs (nQ and nQ), enabling direct connection to differential receivers or bus drivers without external inverters.
Its transparent mode allows real-time data tracking when LE is HIGH; on LE HIGH-to-LOW transition, data present one setup time prior is captured and held stable. Input clamp diodes permit safe interfacing to voltages exceeding VCC using current-limiting resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.0 V to 6.0 V - supports mixed-voltage system integration including 3.3 V and 5 V domains. |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood automotive environments per AEC-Q100 Grade 1. |
| Propagation delay (nD→nQ) | 10 ns max at VCC = 6.0 V - enables high-speed sampling of sensor or communication signals before enable edge. |
| Set-up time (tsu) | 15 ns min at VCC = 6.0 V - defines minimum data stability window before LE falling edge for reliable capture. |
| Output drive (IO) | ±4 mA at VCC = 4.5 V - sufficient to drive standard CMOS loads or small LED indicators directly. |
| Power dissipation | 160 μA ICC max at VCC = 6.0 V and -40 °C to +125 °C - ensures low quiescent current in always-on vehicle modules. |
Pinout & Package
74HC75D-Q100 is housed in a plastic small outline package (SO16), SOT109-1, with 16 leads and 3.9 mm body width. Pin 1 is index-marked; VCC (pin 5) and GND (pin 12) occupy center positions to minimize supply noise coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 14, 11, 8 | 1Q, 2Q, 3Q, 4Q | Complementary latch outputs - active-HIGH true outputs for direct logic-level interfacing. |
| 16, 15, 10, 9 | 1Q, 2Q, 3Q, 4Q | Inverted latch outputs - provide differential signaling capability without external inverters. |
| 2, 3, 6, 7 | 1D, 2D, 3D, 4D | Data inputs - accept standard CMOS logic levels; clamped to support overvoltage-safe interfacing. |
| 4 | LE34 | Active-HIGH enable for latches 3 and 4 - decouples timing control between two functional groups. |
| 13 | LE12 | Active-HIGH enable for latches 1 and 2 - enables synchronized latching of related signal pairs (e.g., CAN TX/RX status bits). |
| 5 | VCC | Positive supply - center-pin placement reduces trace inductance and improves power integrity. |
| 12 | GND | Ground reference - adjacent to VCC for optimal decoupling layout in compact PCB designs. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient, meeting stringent reliability and lifetime requirements. |
| Dual independent enable inputs | LE12 and LE34 allow partitioned latching - e.g., isolate safety-critical vs. non-critical signal groups in ADAS subsystems. |
| Complementary Q/nQ outputs per latch | Eliminates need for external inverters in differential bus drivers or fail-safe monitoring circuits. |
| Input clamp diodes | Enable robust interfacing to voltages > VCC (e.g., 12 V sensor lines) using simple series resistors - no level shifters required. |
| Low dynamic power (CPD = 42 pF/latch) | Reduces switching power in high-frequency latching applications such as multiplexed display or ADC sample hold. |
Applications
| Engine Control Unit (ECU) Input Capture | Body Control Module (BCM) Signal Isolation |
|---|---|
Use Scenario: Capturing analog-to-digital converter (ADC) output codes and sensor status flags before microcontroller read cycle. IC Role / Device Role / Timing Role: Transparent latch holding sampled values during CPU interrupt latency; LE12/LE34 timed to match ADC conversion completion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad transparent latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC75DR | Non-automotive grade; rated only to +85 °C; lacks AEC-Q100 qualification and extended temp characterization. | Suitable for industrial or consumer boards where ambient stays below 85 °C and automotive compliance is not required. | Select only if cost sensitivity outweighs environmental ruggedness and long-term reliability validation needs. |
| 74LVC75APWJ | Lower VCC range (1.65 V–3.6 V); higher speed (tpd = 3.2 ns typ at 3.3 V); no complementary outputs - Q only. | Preferred in battery-powered infotainment systems needing ultra-low voltage operation and faster latching, but requires external inverters for differential paths. | Choose when system operates exclusively at 3.3 V and timing budget is tighter than 10 ns, accepting added board area for inversion. |
Compared with SN74HC75DR and 74LVC75APWJ, the 74HC75D-Q100 uniquely combines automotive qualification, full 2–6 V operation, and native complementary outputs - making it the sole option for safety-critical latching in wide-temperature, mixed-voltage automotive ECUs.

FAQ
What is the maximum allowable input voltage when VCC = 5.0 V?
The absolute maximum input voltage is VCC + 0.5 V = 5.5 V, supported by internal clamp diodes. Exceeding this risks permanent damage. For sustained 12 V interfacing, use a series current-limiting resistor calculated to restrict IIK to ≤ ±20 mA per input, as specified in Table 4.
Can LE12 and LE34 be tied together for single-enable operation?
Yes - connecting LE12 and LE34 enables all four latches simultaneously. This configuration maintains full functionality but eliminates independent group control. Ensure combined load capacitance remains within fan-out limits; no additional buffering is required due to CMOS input structure.
Does the device support hot insertion or live swapping?
No - the 74HC75D-Q100 lacks Ioff protection and bus-hold circuitry. Power sequencing must follow VCC before inputs, and inputs must remain within 0 V to VCC during power-up/down. Hot insertion may cause latch-up or undefined output states.
How does the latch behave when LE is held LOW indefinitely?
When LE12 or LE34 is held LOW, the corresponding latches retain their last captured data state indefinitely - outputs remain stable regardless of subsequent changes on D inputs. This behavior enables static signal storage without clocking, ideal for configuration or fault flag retention.
