Product details
Overview
74HC151BQ-Q100 from Nexperia is an automotive-grade 8-input CMOS multiplexer with three binary select lines (S0–S2), active-low enable (E), complementary outputs (Y and Y̅), and operation across 2.0 V to 6.0 V supply. It routes one of eight data inputs (I0–I7) to Y/Y̅ based on select logic, supports -40 °C to +125 °C ambient, and features clamp diodes for overvoltage-tolerant interfacing in body control modules.
For engineers reviewing the 74HC151BQ-Q100 datasheet, 74HC151BQ-Q100 pinout, 74HC151BQ-Q100 application, or 74HC151BQ-Q100 equivalent, this page delivers verified functional behavior, DHVQFN16 package layout, AEC-Q100 Grade 1 qualification status, propagation delay (15–43 ns at VCC = 6.0 V), and real-world automotive signal routing use cases - all grounded in Nexperia's Rev. 7 product data sheet.
Technical Context
The device implements a standard 3-bit binary decoder driving eight AND gates, with output OR-ing and complementation to produce true and inverted multiplexed outputs. Its enable input (E) forces both outputs to fixed logic states (Y = LOW, Y̅ = HIGH) when asserted, providing synchronous gating without external logic.
Input thresholds follow CMOS-level compatibility (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC), ensuring robust noise immunity and direct interfacing with other HC-series logic. The DHVQFN16 package includes side-wettable flanks for AOI-compatible solder joint inspection - critical for automotive PCB assembly traceability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 2.0 V to 6.0 V - supports wide-battery automotive systems including 3.3 V and 5 V domains without level shifters. |
| Propagation delay (In → Y) | 15 ns (typ) at VCC = 6.0 V, CL = 50 pF - enables reliable timing in sub-66 MHz digital control paths. |
| Output drive strength | ±4.0 mA at VCC = 4.5 V - sufficient to drive 10–15 pF loads or fan-out to 10+ HC inputs without buffering. |
| Operating temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications. |
| Input clamp current | ±20 mA - allows safe interface to signals exceeding VCC using external current-limiting resistors. |
| Power dissipation capacitance | 40 pF - used to calculate dynamic power: PD = CPD × VCC² × fi × N, enabling accurate thermal modeling. |
| ESD rating (HBM) | >2000 V - exceeds JEDEC JS-001 Class 2, reducing risk of field failure during handling and assembly. |
Pinout & Package
DHVQFN16 package (SOT763-1): 2.5 mm × 3.5 mm × 0.85 mm body, no leads, 16 terminals, side-wettable flanks for AOI, thermal pad (terminal 1) electrically isolated unless connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Thermal pad / GND reference | Non-electrical thermal slug; may be left floating or tied to GND for improved heat dissipation - no solder requirement. |
| 2 | I0 | Data input 0 - routed to Y/Y̅ when S2S1S0 = 000 and E = LOW. |
| 3 | I1 | Data input 1 - selected when S2S1S0 = 001 and E = LOW. |
| 4 | I2 | Data input 2 - selected when S2S1S0 = 010 and E = LOW. |
| 5 | Y | True multiplexer output - reflects selected input when E = LOW; forced LOW when E = HIGH. |
| 6 | Y̅ | Inverted multiplexer output - complements Y; forced HIGH when E = HIGH. |
| 7 | E | Enable input (active LOW) - disables output routing and forces Y = LOW / Y̅ = HIGH when HIGH. |
| 8 | GND | Ground reference - primary return path for all internal logic and I/O currents. |
| 9 | S2 | Select bit 2 - MSB of 3-bit address selecting I0–I7 (S2S1S0 = binary index). |
| 10 | S1 | Select bit 1 - middle bit of 3-bit address; determines quadrant of input selection. |
| 11 | S0 | Select bit 0 - LSB of 3-bit address; selects individual input within quadrant. |
| 12 | I7 | Data input 7 - selected when S2S1S0 = 111 and E = LOW. |
| 13 | I6 | Data input 6 - selected when S2S1S0 = 110 and E = LOW. |
| 14 | I5 | Data input 5 - selected when S2S1S0 = 101 and E = LOW. |
| 15 | I4 | Data input 4 - selected when S2S1S0 = 100 and E = LOW. |
| 16 | VCC | Positive supply - powers internal logic and output buffers; decoupling required within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C, including temperature cycling, HTOL, and ESD stress per JEDEC standards. |
| CMOS-level input thresholds | VIH ≥ 0.7×VCC and VIL ≤ 0.3×VCC ensure noise margins >1.0 V at 5 V supply, supporting robust operation in noisy engine bays. |
| Complementary dual outputs | Simultaneous Y and Y̅ delivery eliminates need for external inverters in differential-sensing or latch-based sampling circuits. |
| Clamp diode protection | Integrated input diodes allow safe connection to voltages up to VCC + 0.5 V using series resistors - simplifies sensor interface design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-input multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT151BQ-Q100 | TTL-compatible inputs (VIH = 2.0 V min), slightly higher propagation delay (22 ns typ at VCC = 4.5 V vs. 19 ns for HC). | Better suited for mixed-logic systems with legacy 5 V TTL microcontrollers or FPGAs lacking HC-level thresholds. | Select when interfacing with older 5 V logic families; avoid if system uses 3.3 V HC-only signaling. |
| SN74LV151AQPWRQ1 | TI's AEC-Q100 Grade 1 LV-family part; lower VCC range (1.65–5.5 V), higher drive (±12 mA), but larger TSSOP-16 footprint. | Preferred where higher output current or 1.8 V logic compatibility is required, e.g., ADAS domain controllers with mixed-voltage I/O. | Choose for 1.8 V/3.3 V hybrid systems; not drop-in due to different pinout and thermal pad configuration. |
Compared with 74HC151BQ-Q100, the 74HCT151BQ-Q100 offers TTL input compatibility at the cost of marginally slower speed and reduced noise immunity, while SN74LV151AQPWRQ1 provides broader voltage support and stronger drive but requires PCB redesign due to non-identical package and pin mapping.

FAQ
Is the thermal pad (Terminal 1) required to be soldered to ground?
No. Terminal 1 is a non-electrical thermal pad with no electrical or mechanical solder requirement. If soldered, it must remain electrically floating or be connected to GND - never left as a floating metal island. This design choice maintains thermal performance while avoiding unintended ground loops in sensitive analog sections.
Can 74HC151BQ-Q100 operate reliably at 2.0 V supply in automotive environments?
Yes. The device is fully specified down to 2.0 V across -40 °C to +125 °C, with VIH ≥ 1.5 V and VOL ≤ 0.26 V at 4.0 mA load - meeting minimum noise margin and drive requirements for low-voltage battery-sag conditions typical in start-stop systems.
What is the maximum clock rate supported for sequential input scanning?
Based on worst-case propagation delay (43 ns at VCC = 6.0 V, -40 °C to +125 °C) and setup/hold margins, the maximum reliable sequential scan rate is 12 MHz - sufficient for sampling 8 inputs every 667 ns in time-division multiplexed sensor monitoring applications.
Does the enable input (E) affect propagation delay measurements?
Yes. Propagation delay from E to Y/Y̅ is separately characterized (12–38 ns depending on VCC and temperature) and is faster than data-path delays. When E transitions, outputs settle to forced states within guaranteed timing - critical for synchronous gating in safety-critical interrupt masking circuits.
