Product details
Overview
74HC157PW-Q100 from Nexperia is an automotive-qualified quad 2-input multiplexer IC with CMOS-level inputs, 16-pin TSSOP package, -40 °C to +125 °C operating range, and 2.0 V–6.0 V supply voltage. It implements four independent data-select functions using a shared select (S) and active-low enable (E), enabling signal routing in engine control units and ADAS domain controllers.
For engineers reviewing the 74HC157PW-Q100 datasheet, 74HC157PW-Q100 pinout, 74HC157PW-Q100 application, or 74HC157PW-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, propagation delay ≤25 ns at 4.5 V, input clamping diodes for overvoltage tolerance, and compatibility with both 3.3 V and 5 V logic systems.
Technical Context
This device integrates four independent 2:1 multiplexers sharing common S and E control lines. Each channel routes either I0 or I1 to its Y output based on S state, while E forces all outputs LOW when HIGH - enabling synchronized channel disable across automotive subsystems.
Input clamping diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The CMOS input structure provides high noise immunity (>40% VCC), and latch-up performance exceeds 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.0 V to 6.0 V - supports direct interface with 3.3 V microcontrollers and legacy 5 V automotive modules |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood and powertrain applications per AEC-Q100 Grade 1 |
| Propagation delay | 13 ns (typ) at VCC = 4.5 V, CL = 50 pF - enables reliable timing in 20+ MHz digital control loops |
| Input voltage thresholds | VIH = 3.15 V, VIL = 1.35 V at VCC = 4.5 V - ensures robust noise margin against automotive electrical transients |
| Output drive strength | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple 74HC inputs or short PCB traces without buffering |
| Power dissipation capacitance | 70 pF - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal design |
| ESD protection | HBM >2000 V, CDM >1000 V - meets stringent automotive board-level ESD requirements |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1); 16 leads; body width 4.4 mm; lead pitch 0.65 mm; exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | S (Select) | Common control input: HIGH selects I1, LOW selects I0 across all four channels |
| 2 | 1I0 | Data input 0 for channel 1 - routed to 1Y when S = LOW |
| 3 | 1I1 | Data input 1 for channel 1 - routed to 1Y when S = HIGH |

| 6 | 2I1 | Data input 1 for channel 2 - routed to 2Y when S = HIGH |
| 7 | 2Y | Non-inverting output for channel 2 |
| 8 | GND | Ground reference (0 V) - must be low-impedance connection for noise immunity |
| 9 | 3Y | Non-inverting output for channel 3 |
| 10 | 3I1 | Data input 1 for channel 3 - routed to 3Y when S = HIGH |
| 11 | 3I0 | Data input 0 for channel 3 - routed to 3Y when S = LOW |
| 12 | 4Y | Non-inverting output for channel 4 |
| 13 | 4I1 | Data input 1 for channel 4 - routed to 4Y when S = HIGH |
| 14 | 4I0 | Data input 0 for channel 4 - routed to 4Y when S = LOW |
| 15 | E (Enable) | Active-HIGH enable: forces all Y outputs LOW regardless of S or input states |
| 16 | VCC | Positive supply rail - decoupling capacitor (100 nF) required within 5 mm |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| 74HCT157PW-Q100 | TTL-compatible inputs (VIH = 2.0 V min), identical pinout and timing | Better interoperability with legacy 5 V TTL logic; slightly higher ICC at 125 °C | Select when interfacing with older 5 V microcontrollers or discrete transistor logic |
| SN74LV157APWR | Lower VCC range (2.0–5.5 V), LV logic family, non-automotive qualified | Lacks AEC-Q100 qualification; lower propagation delay (11 ns typ at 3.3 V) but no extended temp support | Consider only for non-automotive industrial or consumer designs requiring faster switching |
Compared with 74HCT157PW-Q100, this HC variant offers superior noise immunity and wider VCC flexibility; versus SN74LV157APWR, it trades raw speed for guaranteed automotive reliability and broader supply tolerance.

FAQ
Can 74HC157PW-Q100 operate reliably at 125 °C junction temperature?
Yes. The device is fully specified and tested from -40 °C to +125 °C ambient per AEC-Q100 Grade 1. Static parameters (VIH/VIL, VOH/VOL) and dynamic timing (tpd, tt) are guaranteed across this range, and total power dissipation is derated linearly at 8.5 mW/K above 91 °C for the TSSOP16 package.
What is the function of the unconnected thermal pad on the bottom of the TSSOP16 package?
The exposed pad in SOT403-1 is not electrically connected and has no internal bond. Nexperia specifies it may remain floating or be soldered to GND for thermal enhancement, but no electrical requirement exists. If connected, it must not introduce ground loops or compromise signal integrity on adjacent traces.
How does the enable (E) input interact with the select (S) input during operation?
E is asynchronous and dominant: when E = HIGH, all four Y outputs are forced LOW regardless of S state or input values. Only when E = LOW does S determine whether I0 or I1 is passed to each Y output. This allows independent channel gating and global output disable in safety-critical sequences.
Are input clamp diodes present on all 14 signal pins (excluding VCC and GND)?
Yes. All 14 signal pins - S, E, and the eight I0/I1 inputs - include integrated clamp diodes to VCC and GND. This permits safe interface to voltages up to VCC + 0.5 V or down to GND − 0.5 V when used with appropriate series current-limiting resistors, a key feature for automotive sensor signal conditioning.
