Product details
Overview
74HCT151PW-Q100 from Nexperia is an automotive-grade 8-input digital multiplexer with TTL-compatible inputs, complementary outputs (Y and Y), active-low enable (E), and three binary select lines (S0–S2). It operates from 4.5 V to 5.5 V across –40 °C to +125 °C, delivers propagation delays as low as 16 ns (E→Y at VCC = 4.5 V), and features side-wettable flanks in its TSSOP16 package for AOI-capable solder joint inspection.
For engineers reviewing the 74HCT151PW-Q100 datasheet, 74HCT151PW-Q100 pinout, 74HCT151PW-Q100 application, or 74HCT151PW-Q100 equivalent, this device is selected for deterministic signal routing in engine control units, ADAS sensor data aggregation, and infotainment I/O expansion where AEC-Q100 Grade 1 qualification, low propagation skew, and robust noise immunity are required.
Technical Context
The 74HCT151PW-Q100 implements a single-pole, 8-throw analog/digital switch function using standard CMOS logic gates with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5 V). Its internal architecture routes one of eight data inputs (I0–I7) to the true output (Y) and inverted output (Y) based on the 3-bit binary code applied to S0–S2, while E forces both outputs into fixed states (Y = LOW, Y = HIGH) when asserted.
It uses non-inverting data path logic with clamp diodes on all inputs for overvoltage tolerance, supports dynamic power calculation via CPD = 40 pF, and meets JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) interface standards - enabling interoperability with mixed-voltage automotive subsystems without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 5.5 V - Ensures compatibility with 5 V automotive power rails and stable operation under load dump or cold-crank conditions. |
| Operating Temperature | –40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and transmission control module deployment. |
| Propagation Delay (E→Y) | 16 ns (typ) at VCC = 4.5 V - Enables real-time enable/disable control in time-critical sensor arbitration paths. |
| Input Thresholds | VIH = 2.0 V, VIL = 0.8 V - Matches legacy TTL logic families without external biasing or translation. |
| Output Drive Strength | ±4 mA at VCC = 4.5 V - Sufficient to drive multiple 74-series inputs or small capacitive loads (<50 pF) directly. |
| Power Dissipation Capacitance | CPD = 40 pF - Allows accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal budgeting in dense PCB layouts. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - Supports handling and assembly in standard automotive manufacturing environments. |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1), 16-pin, body width 4.4 mm, side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 12, 13, 14, 15 (I0–I7) | Data inputs | Eight independent digital inputs routed selectively to Y/Y; accept TTL-level signals and include clamp diodes for overvoltage protection. |
| 5 (Y) | True output | Active-HIGH selected data path output; sinks/source up to ±4 mA; complements Y output state. |
| 6 (Y) | Inverted output | Active-LOW complement of Y; enables differential signaling or direct connection to NOR/NAND gate inputs. |
| 7 (E) | Enable input (active LOW) | Asynchronous global disable: forces Y = LOW and Y = HIGH regardless of select inputs - critical for bus isolation. |
| 8 (GND) | Ground reference | Primary 0 V return path; must be low-impedance and decoupled locally to suppress switching noise coupling. |
| 9, 10, 11 (S2, S1, S0) | Select address inputs | 3-bit binary control determining which Ix drives Y/Y; latched internally with no metastability risk at valid transition rates. |
| 16 (VCC) | Supply voltage | Positive rail input (4.5–5.5 V); requires local 100 nF ceramic decoupling adjacent to pin for high-frequency transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from –40 °C to +125 °C in automotive powertrain and chassis systems. |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 4.5 V - eliminates need for external level-shifting when interfacing with legacy microcontrollers or sensors. |
| Side-wettable flanks (SWF) | Enables 100% automated optical inspection (AOI) of solder fillets on all 16 terminals - improves manufacturing yield traceability in Tier-1 production. |
| Complementary dual outputs (Y/Y) | Provides simultaneous true and inverted signals for driving differential receivers or reducing external inverters in feedback loops. |
| Clamp diode protected inputs | Allows safe interfacing to voltages up to VCC + 0.5 V or down to –0.5 V using current-limiting resistors - simplifies front-end protection 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 |
|---|---|---|---|
| 74HC151PW-Q100 | CMOS-level inputs (VIH = 3.15 V min at VCC = 4.5 V), higher propagation delay (22 ns E→Y typ), wider VCC range (2.0–6.0 V) | Suitable for mixed-voltage systems with 3.3 V/5 V coexistence; less tolerant of legacy TTL outputs | Select when interfacing with 3.3 V logic families or requiring extended supply flexibility beyond 5 V nominal. |
| SN74LV151AQPWRQ1 | Lower VCC range (2.0–5.5 V), LV logic family (VIH = 1.7 V min), faster tpd (13 ns E→Y typ), same AEC-Q100 Grade 1 rating | Better suited for 3.3 V–dominant domains; not TTL-compatible but offers lower dynamic power (CPD = 25 pF) | Prefer for new designs targeting 3.3 V supply rails and tighter timing budgets, especially in ADAS domain controllers. |
Compared with 74HC151PW-Q100, the 74HCT151PW-Q100 provides guaranteed TTL input compatibility at the cost of slightly higher propagation delay, while SN74LV151AQPWRQ1 trades TTL support for lower voltage operation and improved speed - making each optimal for distinct automotive subsystem voltage and timing architectures.

FAQ
Is the 74HCT151PW-Q100 pin-compatible with the standard 74HCT151 in SO16 or DHVQFN packages?
Yes - the 74HCT151PW-Q100 shares identical pin numbering and functional assignment with the SO16 (74HCT151D-Q100) and DHVQFN16 (74HCT151BQ-Q100) variants. All three use the same I0–I7, Y, Y, E, S0–S2, GND, and VCC pin mapping per the SOT403-1, SOT109-1, and SOT763-1 outlines defined in the datasheet.
What is the maximum clock/data toggle rate supported by the 74HCT151PW-Q100?
The device does not operate on a clock; it is combinatorial. Its maximum usable data rate is governed by propagation delay and transition time: with tpd = 16 ns (E→Y) and tt = 7 ns (Y/Y), reliable operation is confirmed up to 30 MHz input switching frequency under CL = 50 pF loading and VCC = 4.5 V, per dynamic characterization in Table 7.
Can the 74HCT151PW-Q100 drive a 50 pF load directly without external buffering?
Yes - the output drive capability (±4 mA at VCC = 4.5 V) and measured transition times (7 ns typ for Y/Y at CL = 50 pF) confirm direct drive capability for standard PCB traces and typical logic fan-out. No external buffer is required unless trace lengths exceed 10 cm or additional capacitive loading (>75 pF) is present.
Does the side-wettable flank (SWF) feature require special stencil or reflow profile adjustments?
No - SWF is a physical package modification only; standard TSSOP16 stencil apertures and IPC/JEDEC J-STD-020D reflow profiles apply. The flank geometry enables AOI visibility of solder fillets but imposes no changes to paste volume, placement accuracy, or thermal ramp rates during SMT assembly.
