Product details
Overview
74HC253BQ-Q100 from Nexperia is an automotive-qualified dual 4-input multiplexer IC with 3-state outputs, shared S0/S1 select lines, independent nOE controls per channel, and CMOS-level input compatibility. It operates from 2.0 V to 6.0 V across –40 °C to +125 °C and routes one of four binary inputs (e.g., sensor data streams) to each output (1Y/2Y) in vehicle body control modules.
For engineers reviewing the 74HC253BQ-Q100 datasheet, 74HC253BQ-Q100 pinout, 74HC253BQ-Q100 application, or 74HC253BQ-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, DHVQFN16 package with side-wettable flanks for AOI, propagation delay ≤26 ns at VCC = 6.0 V, and separate enable control per multiplexer channel.
Technical Context
This device implements two independent 4:1 multiplexers sharing common select inputs (S0, S1), enabling synchronized routing of two parallel 4-source data paths. Each channel features active-low output enable (1OE, 2OE), non-inverting logic, and high-impedance OFF-state when enabled low.
Input clamping diodes allow safe interfacing with voltages exceeding VCC using current-limiting resistors. The DHVQFN16 package (SOT763-1) provides thermal enhancement and supports automated optical inspection via side-wettable flanks - critical for automotive PCB assembly traceability.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low output enable for multiplexer 1 - drives 1Y to high-impedance when HIGH. |
| 2 | S1 | MSB select input shared by both multiplexers - determines bit position for input selection (00–11). |
| 3 | 1I3 | Data input 3 for channel 1 - selected when S1S0 = 11; routed to 1Y if 1OE = LOW. |
| 4 | 1I2 | Data input 2 for channel 1 - selected when S1S0 = 10; non-inverting path to 1Y. |
| 5 | 1I1 | Data input 1 for channel 1 - selected when S1S0 = 01; TTL/CMOS-compatible input threshold. |
| 6 | 1I0 | Data input 0 for channel 1 - selected when S1S0 = 00; clamped diode allows overvoltage-safe interfacing. |
| 7 | 1Y | Output for multiplexer 1 - 3-state, non-inverting, capable of driving bus loads up to ±7.8 mA. |

Applications
| Body Control Module Data Routing | Instrument Cluster Signal Multiplexing |
|---|---|
Use Scenario: Aggregating door lock status, window position, mirror adjustment, and lighting control signals from distributed sensors into a central BCM MCU. IC Role / Device Role / Timing Role: Dual 4:1 multiplexer selects active sensor group per cycle; S0/S1 synchronized across channels ensures deterministic timing alignment. Use Value: Reduces MCU GPIO count by 8 pins while maintaining independent control of two signal groups - lowers firmware complexity and PCB layer count. | Use Scenario: Consolidating speedometer, tachometer, fuel gauge, and warning lamp signals from multiple ECUs onto a single SPI or CAN-FD interface path to the instrument cluster display controller. IC Role / Device Role / Timing Role: Routes analog or digital sensor outputs to shared ADC or digital input pins; 3-state outputs prevent bus contention during idle cycles. Use Value: Enables time-division multiplexing of four analog gauges using one ADC channel - cuts component cost and improves layout density in space-constrained dashboards. |
| ADAS Camera Interface Switching | Powertrain Diagnostic Bus Sharing |
Use Scenario: Selecting between forward-facing, rear-view, and blind-spot camera video data streams before feeding to image processing SoC. IC Role / Device Role / Timing Role: Acts as high-speed analog switch for LVDS or sub-LVDS pixel data; propagation delay <26 ns preserves timing margins in 30+ fps video pipelines. Use Value: Provides glitch-free source switching without external clock domain synchronization - avoids frame tearing or sync loss during camera handoff. | Use Scenario: Sharing a single diagnostic test port (e.g., UDS over CAN) among engine, transmission, and battery management ECUs during factory end-of-line testing. IC Role / Device Role / Timing Role: Enables sequential access to diagnostic lines via 1OE/2OE gating; S0/S1 selects which ECU's response line connects to tester interface. Use Value: Eliminates need for mechanical relays or dedicated test harnesses - accelerates production line throughput and reduces test fixture maintenance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4:1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT253BQ-Q100 | TTL-compatible inputs (VIH = 2.0 V min); identical pinout and function. | Better suited for interfacing with legacy 5 V TTL logic; slightly higher ICC at VCC = 5.5 V. | Select when integrating with older microcontrollers or discrete transistor logic where input thresholds must match TTL levels. |
| SN74LV253AQPWRQ1 | TI's AEC-Q100 Grade 1 dual 4:1 mux; lower VCC range (1.65–5.5 V); 14 ns tpd at 3.3 V. | Optimized for 3.3 V systems; lacks side-wettable flanks - limits AOI capability in high-reliability automotive lines. | Prefer for cost-sensitive 3.3 V-only designs where AOI is not mandated; verify thermal derating above 106 °C. |
Compared with 74HCT253BQ-Q100, the HC variant offers superior noise immunity and wider voltage flexibility; versus SN74LV253AQPWRQ1, it delivers stronger 5 V drive, guaranteed side-wettable flank inspection, and broader temperature margin - making it optimal for mixed-voltage, high-integrity automotive control units.

FAQ
What is the maximum clock frequency supported by the 74HC253BQ-Q100?
The 74HC253BQ-Q100 does not operate on a clock; it is a combinational logic device. Its usable data rate depends on propagation delay and system setup/hold timing. With tpd ≤ 26 ns at VCC = 6.0 V and tt ≤ 15 ns, it reliably handles asynchronous signal switching up to ~15 MHz in well-terminated 50 pF loads - verified per JEDEC JESD7A and JESD8C standards.
Can the exposed thermal pad on the DHVQFN16 package be grounded?
No - the exposed pad (terminal 1 index area) is not internally connected to GND or any internal node. Per Nexperia's datasheet, it may remain electrically floating or be connected to VCC; grounding it is not recommended and could compromise thermal performance or cause unintended biasing of internal structures.
Does the 74HC253BQ-Q100 support hot insertion or live swapping?
No - the device lacks hot-swap protection circuitry such as slew-rate limiting or back-drive prevention. Applying VCC or signals while other rails are unpowered risks latch-up or ESD damage due to internal clamp diode conduction. Power sequencing per recommended operating conditions (VCC established before inputs) is mandatory.
How does the input clamping diode affect interfacing with 12 V sensors?
The integrated input clamping diodes allow safe interface with voltages up to VCC + 0.5 V. To connect a 12 V sensor, a series current-limiting resistor must be used to restrict IIK to ≤ ±20 mA (per absolute max rating). For VCC = 5 V, a minimum 350 Ω resistor ensures compliance - enabling direct integration without external protection diodes.
