Product details

Overview

74HC151D-Q100/AUJ from Nexperia is an 8-input digital multiplexer IC with 3-bit select lines, active-low enable (E̅), complementary outputs (Y and Y̅), and TTL-compatible inputs. It operates from 2.0 V to 6.0 V, delivers ±5.2 mA output drive at V_CC = 4.5 V, and supports automotive-grade temperature range (−40 °C to +125 °C). It is used in data routing within automotive body control modules.

For engineers reviewing the 74HC151D-Q100/AUJ datasheet, 74HC151D-Q100/AUJ pinout, 74HC151D-Q100/AUJ application, or 74HC151D-Q100/AUJ equivalent, key selection criteria include input voltage compatibility, propagation delay under automotive supply conditions, output drive strength for fan-out loading, and AEC-Q100 qualification status.

Technical Context

This device implements a standard 8:1 data selector logic function using CMOS technology. Its three address inputs (A, B, C) decode one of eight data inputs (I₀–I₇) to the true output (Y), while the complement appears at Y̅. The E̅ input enables or disables both outputs simultaneously.

Propagation delays are specified as t_PHL/t_PLH ≤ 21 ns at V_CC = 4.5 V and T_A = 25 °C. Input thresholds meet TTL levels (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V), ensuring interoperability with legacy logic families in mixed-signal automotive subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	8-input multiplexer with 3-bit binary address decoding and active-low enable
Supply Voltage Range	2.0 V to 6.0 V - supports 3.3 V and 5 V automotive domains without level translation
Output Drive	±5.2 mA at V_CC = 4.5 V - sufficient to drive 10 LS-TTL loads or 20 HC loads
Propagation Delay	≤21 ns (max) at V_CC = 4.5 V - enables reliable timing in sub-50 MHz control paths
Operating Temperature	−40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood applications
Input Thresholds	V_IL ≤ 0.8 V, V_IH ≥ 2.0 V - ensures robust noise margin with TTL-level sources

Pinout & Package

Supplied in 16-pin SOIC package (SO16, body width 3.9 mm, pitch 1.27 mm), compliant with JEDEC MS-012AC.

Pin/Terminal	Circuit Role	Design Meaning
1 (E̅)	Active-low enable input	Disables all outputs (Y = Y̅ = high-impedance) when logic high
2–4 (A, B, C)	Address select inputs	Binary-encoded selection of I₀–I₇; A = LSB, C = MSB
5–12 (I₀–I₇)	Data inputs	Eight parallel digital inputs routed to Y/Y̅ based on address state
13 (Y̅)	Inverted output	Complement of selected input; active-high logic polarity
14 (Y)	True output	Exact copy of selected input; active-high logic polarity
16 (V_CC)	Positive supply	Connects to main system rail (2.0–6.0 V); decoupling required
8 (GND)	Ground reference	Common return path for all logic and output currents

Key Features

Feature	Design Value
AEC-Q100 qualified	Grade 1 (−40 °C to +125 °C) qualification confirmed - suitable for engine control, lighting, and gateway ECUs
CMOS technology	Low static current (I_CC ≤ 2 µA at V_CC = 6 V) - reduces quiescent power in always-on modules
High noise immunity	Typical noise margin > 1.0 V at V_CC = 4.5 V - improves reliability in electrically noisy vehicle environments
Wide V_CC range	Operates across 2.0–6.0 V - simplifies integration into 3.3 V microcontroller interfaces and 5 V sensor signal chains

Applications

Automotive Body Control Unit

Instrument Cluster Signal Routing

Use Scenario: Consolidating switch inputs (door locks, window switches, mirror controls) into a single MCU GPIO port.

IC Role / Device Role / Timing Role: Data selector routing up to eight mechanical inputs to one MCU interrupt-capable pin via address encoding.

Use Value: Reduces MCU pin count and PCB trace routing complexity while maintaining deterministic response latency (<21 ns).

Use Scenario: Dynamically selecting between analog sensor signals (fuel level, coolant temp, battery voltage) for ADC sampling.

IC Role / Device Role / Timing Role: Analog multiplexing enabler - used with external buffer to condition and route signals before ADC input.

Use Value: Enables shared ADC resource across multiple sensors without dedicated converters, lowering BOM cost.

LED Driver Address Decoding

Diagnostic Test Point Selection

Use Scenario: Selecting one of eight LED driver enable lines in adaptive lighting control modules.

IC Role / Device Role / Timing Role: Digital enable gate controlling individual LED string drivers based on CAN message payload bits.

Use Value: Provides precise, glitch-free activation sequencing with no additional timing components required.

Use Scenario: Routing internal ECU test signals (CAN TX/RX, LIN, reset, watchdog) to a single debug header pin.

IC Role / Device Role / Timing Role: Diagnostic access multiplexer enabling field service tools to monitor different internal buses selectively.

Use Value: Eliminates need for manual jumper configuration during validation and repair, improving test repeatability.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 8:1 multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74HC151QPWRQ1	TI part; identical logic function, same AEC-Q100 Grade 1 rating, but uses TSSOP-16 package (4.4 mm width)	Requires PCB footprint redesign due to narrower body and different thermal pad layout	Preferred when board space is constrained and TSSOP assembly capability exists
MC74HC151ADTR2G	ON Semiconductor part; same pinout and function, but rated only to +105 °C (non-AEC-Q100)	Not approved for under-hood use; limited to cabin or infotainment modules	Acceptable for cost-sensitive interior applications where full automotive qualification is not mandated

Compared with SN74HC151QPWRQ1 and MC74HC151ADTR2G, the 74HC151D-Q100/AUJ offers drop-in compatibility in SO16 footprints with guaranteed AEC-Q100 Grade 1 performance, making it optimal for new designs targeting broad automotive deployment without package conversion effort.

FAQ

Is the 74HC151D-Q100/AUJ pin-compatible with standard 74HC151 devices?

Yes - it shares identical pinout, logic function, and electrical specifications with industry-standard 74HC151 devices, including the non-automotive 74HC151D. The "-Q100" suffix denotes AEC-Q100 qualification and enhanced process controls, not pin or functional changes.

What is the maximum clock frequency supported for address switching?

The device does not operate on a clock; it is combinational logic. Maximum reliable address transition rate is governed by propagation delay (≤21 ns) and setup/hold timing of input signals. For clean operation, address changes should be stable ≥5 ns before data input transitions in synchronous systems.

Does the 74HC151D-Q100/AUJ support 3.3 V-only operation?

Yes - it functions correctly across 2.0 V to 6.0 V, including 3.3 V nominal supplies. Input thresholds remain compatible with 3.3 V logic families, and output VOH/VOL meet HC specifications at V_CC = 3.3 V, enabling direct interface with 3.3 V microcontrollers.

Can Y and Y̅ outputs drive LEDs directly?

No - while output drive is ±5.2 mA, the outputs are designed for logic-level interfacing, not current sourcing/sinking to LEDs. Direct LED connection risks exceeding absolute maximum ratings and violates recommended operating conditions; an external transistor or LED driver IC is required.
