Product details
Overview
74LVC157APW-Q100 from Nexperia is an automotive-grade quad 2-input multiplexer with active-low enable (E), common select input (S), and true (non-inverted) outputs (1Y–4Y). It operates from 1.2 V to 3.6 V, tolerates 5 V inputs, and functions across –40 °C to +125 °C. Used in mixed-voltage data routing, such as selecting between two register banks for four parallel output buses in automotive control modules.
For engineers reviewing the 74LVC157APW-Q100 datasheet, 74LVC157APW-Q100 pinout, 74LVC157APW-Q100 application, or 74LVC157APW-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, 5 V-tolerant inputs enabling 3.3 V/5 V level translation, propagation delay down to 2.5 ns at 3.0–3.6 V, and TSSOP16 package with side-wettable flanks for AOI-compatible solder joint inspection.
Technical Context
This device implements four independent 2:1 multiplexers sharing one select (S) and one enable (E) control line. Each channel routes either I0 or I1 to its corresponding Y output based on S state, with E overriding all selections when HIGH to force all outputs LOW - a synchronous disable function critical for bus arbitration and power-aware signal gating.
Its CMOS design supports direct TTL-level interfacing and complies with JEDEC standards JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V). Input clamping and ESD protection (HBM >2000 V, CDM >1000 V) ensure robustness in automotive environments where voltage transients and electrostatic discharge are common.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - enables operation in ultra-low-power microcontroller domains and compatibility with modern 1.8 V/2.5 V/3.3 V logic rails. |
| Input Voltage Tolerance | Up to 5.5 V - allows safe interfacing with legacy 5 V logic without external level shifters in mixed-voltage systems. |
| Propagation Delay (tpd) | 2.5 ns typical at VCC = 3.0–3.6 V - ensures minimal timing skew in high-speed data path selection for real-time control loops. |
| Operating Temperature | –40 °C to +125 °C - meets automotive under-hood and engine-control unit (ECU) thermal requirements per AEC-Q100 Grade 1. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive standard CMOS loads and short PCB traces without buffering. |
| Power Dissipation Capacitance (CPD) | 15.9 pF at VCC = 3.0–3.6 V - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal budgeting in dense ECUs. |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1), 16 leads, body width 4.4 mm, with side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Common data select input | Controls which input (I0 or I1) is routed to all four outputs; logic HIGH selects I1, LOW selects I0. |
| 2 (1I0), 3 (1I1), 4 (1Y) | Channel 1 data inputs and output | 1I0 and 1I1 feed first multiplexer; 1Y delivers selected input - identical structure replicated for channels 2–4 (pins 5–7, 9–11, 12–14). |
| 15 (E) | Enable input (active LOW) | When HIGH, forces all outputs LOW regardless of S or data inputs - provides global output disable for bus contention avoidance. |
| 16 (VCC), 8 (GND) | Power supply terminals | VCC supplies core logic; GND is reference for all I/O - decoupling near these pins is required for noise immunity in automotive switching environments. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive applications with operating temperature range –40 °C to +125 °C and rigorous stress testing. |
| 5 V tolerant inputs | Accepts 5 V logic signals while powered from 1.2–3.6 V supply - eliminates need for discrete level translators in mixed-voltage designs. |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joints on bottom-terminated TSSOP package - improves manufacturing yield and field reliability. |
| Low dynamic power consumption | CPD = 15.9 pF and ICC < 40 μA at VCC = 3.6 V - reduces heat generation and extends battery life in always-on vehicle subsystems. |
| JEDEC-compliant voltage interfaces | Meets JESD8-7A, JESD8-5A, and JESD8-C/JESD36 standards - guarantees interoperability with industry-standard 1.8 V, 2.5 V, and 3.3 V logic families. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC157APWR | Non-automotive grade; rated –40 °C to +85 °C; no AEC-Q100 qualification; identical electrical specs and pinout. | Lacks extended temperature and stress validation required for under-hood or safety-related automotive use. | Select only for non-automotive industrial or consumer applications where cost sensitivity outweighs qualification needs. |
| 74LVC157ABQ-Q100 | DHVQFN16 package (2.5 × 3.5 × 0.85 mm); same AEC-Q100 Grade 1 rating and electrical performance; no leads, side-wettable flanks. | Better thermal dissipation and smaller footprint than TSSOP16; requires reflow profile optimization for QFN mounting. | Prefer for space-constrained, thermally demanding automotive modules where board area and thermal resistance are critical. |
Compared with SN74LVC157APWR, the 74LVC157APW-Q100 adds AEC-Q100 qualification and extended temperature support without sacrificing speed or voltage flexibility; versus 74LVC157ABQ-Q100, it trades compactness and thermal efficiency for easier manual inspection and legacy TSSOP assembly compatibility.

FAQ
What is the maximum input voltage the 74LVC157APW-Q100 can tolerate on its I/O pins?
The device supports 5 V tolerant inputs: any input pin (S, E, I0, I1) accepts voltages up to 5.5 V regardless of VCC setting (1.2–3.6 V), enabling seamless integration with legacy 5 V peripherals without external level-shifting circuitry - verified per datasheet Table 4 and Section 1. General description.
How does the enable (E) pin function, and what happens when it is asserted HIGH?
Pin E is active LOW: when driven HIGH, all four outputs (1Y–4Y) are forced LOW irrespective of S state or input values - this hard-disable behavior prevents bus contention during system reset or power sequencing. The function table in Section 6 confirms E=H → nY=L for all channels.
Is the 74LVC157APW-Q100 compatible with 1.8 V logic systems, and what are the VIH/VIL thresholds at that supply?
Yes - at VCC = 1.8 V (within 1.65–1.95 V range), VIH = 0.65 × VCC = 1.17 V min and VIL = 0.35 × VCC = 0.63 V max, ensuring reliable recognition of 1.8 V logic HIGH/LOW levels. These values are specified in Table 6 (Static characteristics) and align with JESD8-7A compliance.
Does the TSSOP16 package of the 74LVC157APW-Q100 support automated optical inspection (AOI), and how is this achieved?
Yes - the SOT403-1 package features side-wettable flanks (SWF), where solder wets vertically along the package edge during reflow, creating a reflective surface visible to AOI cameras. This enables 100% solder joint inspection without X-ray, as confirmed in Section 2 Features and benefits and Figure 11 package outline.
