Product details
Overview
SN74HCS153QDRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive dual 4-to-1 CMOS multiplexer with Schmitt-trigger inputs, operating from 2 V to 6 V supply, delivering ±7.8-mA output drive at 6 V, and consuming only 100 nA typical ICC. It performs asynchronous data routing in vehicle body control modules, infotainment I/O expansion, and sensor signal selection circuits.
For engineers reviewing the SN74HCS153QDRQ1 datasheet, SN74HCS153QDRQ1 pinout, SN74HCS153QDRQ1 application, or SN74HCS153QDRQ1 equivalent, key selection criteria include its dual-channel independent strobe control (1G/2G), Schmitt-trigger noise immunity (ΔVT = 0.6 V min at 6 V), automotive temperature range (–40°C to +125°C), and WQFN wettable flank package for AOI-compatible solder joint inspection.
Technical Context
The SN74HCS153QDRQ1 implements two independent 4:1 multiplexers sharing common address inputs (A, B) but featuring separate active-low strobe terminals (1G, 2G) that force respective outputs (1Y, 2Y) low regardless of address state. Its Schmitt-trigger inputs provide hysteresis (VT+ = 2.1 V, VT– = 1.2 V at 6 V), enabling robust operation with slow-rising signals and noise rejection up to ±0.6 V peak-to-peak.
It uses balanced CMOS push-pull outputs capable of sourcing/sinking ±7.8 mA at 6 V while maintaining VOL ≤ 0.33 V and VOH ≥ 5.4 V under load. The device operates asynchronously with propagation delays as low as 6 ns (typ) at 6 V and CL = 50 pF, and supports full rail-to-rail input voltage range (0 V to VCC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 6 V - enables direct interface with 3.3 V and 5 V automotive subsystems without level shifting |
| Operating Temperature | –40°C to +125°C (Grade 1) - qualified for engine bay, transmission control, and ADAS ECU environments |
| Output Drive Strength | ±7.8 mA at 6 V - sufficient to drive multiple CMOS loads or small LEDs without external buffers |
| Input Hysteresis (ΔVT) | 0.6 V (min) at 6 V - rejects noise spikes up to 600 mVpp and tolerates slow input edges (>1 µs rise/fall) |
| Quiescent Supply Current | 100 nA (typ) - supports ultra-low-power always-on monitoring functions in battery-backed systems |
| Propagation Delay | 7 ns (typ) at 6 V - ensures timing-critical signal routing in real-time vehicle networks |
| Input Leakage Current | ±100 nA (max) - minimizes current draw on high-impedance sensor lines and pull-up/pull-down networks |
Pinout & Package
SN74HCS153QDRQ1 is packaged in a 16-pin WQFN (WBQB) with wettable flanks (3.60 mm × 2.60 mm body), thermal pad (connected to GND or left floating), and lead pitch of 0.4 mm - optimized for automated optical inspection (AOI) and high-density automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1G, 15 (2G) | Active-low strobe input per channel | Forces 1Y or 2Y low independently - enables channel gating without changing address logic |
| 2, 14 (A, B) | Binary address select inputs | Shared by both multiplexers - selects one of four data inputs (C0–C3) per channel simultaneously |
| 3–6, 10–13 (1C0–1C3, 2C0–2C3) | Data inputs | Eight total inputs - each channel accepts four independent digital sources (e.g., sensor outputs, switch states) |
| 7 (1Y), 9 (2Y) | CMOS push-pull outputs | Drive downstream logic or indicators directly - no external pull-ups required |
| 8 (GND), 16 (VCC) | Power terminals | Decoupling capacitor (0.1 µF) must be placed adjacent to VCC/GND pins to suppress switching noise |
| Thermal Pad | Exposed bottom pad | Improves thermal dissipation - recommended connection to GND plane for enhanced reliability in hot environments |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-to-1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCS153PWQ1 | TSSOP-16 package (5.00 mm × 4.40 mm); no wettable flanks; RθJA = 141.2°C/W | Better suited for prototyping or legacy board designs with larger pad spacing; less suitable for AOI-reliant high-volume production | Select when manual rework or through-hole compatibility is prioritized over automated inspection capability |
| SN74HCS153DQ1 | SOIC-16 package (9.90 mm × 3.90 mm); higher thermal resistance (RθJA = 122.2°C/W); no wettable flanks | Preferred for industrial-grade non-automotive applications where footprint size is secondary to ease of hand-soldering | Choose for cost-sensitive applications where AEC-Q100 qualification is retained but WQFN-specific manufacturability is not required |
Compared with SN74HCS153PWQ1 and SN74HCS153DQ1, the SN74HCS153QDRQ1 offers superior thermal performance (RθJA = 97.3°C/W), AOI-compatible wettable flanks, and smallest footprint - making it optimal for space-constrained, high-reliability automotive modules requiring zero-defect solder joint verification.

FAQ
What is the maximum clock frequency supported by SN74HCS153QDRQ1?
The SN74HCS153QDRQ1 achieves a maximum switching frequency of 29 MHz at 6 V and –40°C to +125°C ambient. This specification is measured with CL = 50 pF and accounts for worst-case propagation delay (tpd = 14 ns max at 6 V). The actual usable frequency in a design depends on load capacitance, trace impedance, and supply stability - values exceeding 50 pF will reduce achievable speed.
Does SN74HCS153QDRQ1 require external pull-up resistors on its inputs?
No, SN74HCS153QDRQ1 does not require external pull-up resistors on its inputs due to integrated Schmitt-trigger architecture. However, unused inputs must be terminated to VCC or GND to prevent floating states. A 10-kΩ resistor is recommended if dynamic control is needed, but direct connection is acceptable for static configuration - this avoids leakage-induced logic instability and ensures deterministic operation.
Can SN74HCS153QDRQ1 drive LED indicators directly?
Yes, SN74HCS153QDRQ1 can drive standard 5-mm LEDs directly when operated at 5 V or 6 V supply. With ±7.8-mA output drive capability and VOL ≤ 0.33 V at 6 V, it supports series resistor calculations yielding ~5 mA forward current (e.g., 470 Ω with 2.1 V LED drop at 6 V). Ensure total output current per channel remains within absolute maximum ratings (±35 mA continuous) and derate for ambient temperature.
How does the wettable flank feature benefit SN74HCS153QDRQ1 in automotive manufacturing?
The wettable flank feature on SN74HCS153QDRQ1 enables reliable side-fillet formation during reflow soldering, allowing automated optical inspection (AOI) systems to verify solder joint integrity on all four sides of the WQFN package. This eliminates manual visual inspection, reduces field failure risk from voided joints, and supports zero-defect quality requirements mandated by IATF 16949 for Tier-1 automotive suppliers.
Is SN74HCS153QDRQ1 compatible with 1.8-V logic systems?
No, SN74HCS153QDRQ1 is not compatible with 1.8-V logic systems. Its minimum specified supply voltage is 2 V, and input thresholds (VT+ = 0.7 V min at 2 V) are not guaranteed to function correctly below that level. Attempting operation at 1.8 V may result in undefined output states, increased ICC, or failure to meet timing specifications - use TI's SN74LVC153 or similar 1.65–3.6-V logic family for 1.8-V interfaces.
