Product details
Overview
74CBTLV3253D-Q100 from Nexperia is an automotive-qualified dual 1-of-4 CMOS bus switch with two independent 4-channel multiplexer/demultiplexer sections, 5 Ω typical ON-resistance at 3.3 V, -40 °C to +125 °C operating range, and IOFF partial power-down protection - used for high-speed signal routing in ADAS sensor interfaces and infotainment data buses.
For engineers reviewing the 74CBTLV3253D-Q100 datasheet, 74CBTLV3253D-Q100 pinout, 74CBTLV3253D-Q100 application, or 74CBTLV3253D-Q100 equivalent, key selection criteria include rail-to-rail analog switching capability, sub-0.25 ns propagation delay, Schmitt-trigger control inputs for noise immunity, and AEC-Q100 Grade 1 qualification for under-hood automotive use.
Technical Context
This device implements two independent bidirectional analog/digital multiplexers sharing common select lines (S0, S1) and separate output enable inputs (1OE, 2OE), enabling simultaneous channel selection across both sections. Each section routes one A-port to one of four B-ports (1B1–1B4 or 2B1–2B4) when its OE is LOW.
IOFF circuitry actively disables all switches during power-down, blocking backflow current even when VCC = 0 V and I/O voltages remain active up to VCC + 0.5 V. Schmitt-trigger inputs on S0, S1, 1OE, and 2OE ensure clean switching with input rise/fall times up to 200 ns/V across the full 2.3 V–3.6 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.3 V to 3.6 V - supports direct interface with 2.5 V and 3.3 V logic domains without level translation |
| ON-resistance (RON) | 4.0 Ω typical at VCC = 3.3 V, ISW = 64 mA - enables low-loss signal pass-through for analog and digital signals up to 302 MHz bandwidth |
| Propagation delay (tpd) | 0.15 ns typical - negligible timing impact in high-speed parallel bus or sensor data path applications |
| Enable/disable time (ten/tdis) | 1.0 ns min, 4.4 ns max at VCC = 3.3 V - ensures fast channel reconfiguration for dynamic signal routing |
| IOFF leakage | ±10 μA max at VCC = 0 V - prevents damaging back-current during hot-swap or partial power-down sequences |
| ESD rating | HBM >2000 V, CDM >1000 V - robust handling in automated PCB assembly and automotive service environments |
| Operating temperature | -40 °C to +125 °C - qualified for engine compartment and transmission control unit mounting locations |
Pinout & Package
74CBTLV3253D-Q100 uses the SO16 plastic small outline package (SOT109-1), 16-pin, 3.9 mm body width, with standard gull-wing lead form suitable for reflow and wave soldering. Pin 1 index located at top-left corner with notch marking.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1OE, 2OE | Active-LOW output enable inputs - independently disable each 4-channel mux section; must be pulled HIGH via resistor during power-up to guarantee OFF-state |
| 2, 14 | S1, S0 | Binary select inputs - determine which of four B-ports connects to corresponding A-port (1A/2A); Schmitt-triggered for slow-edge tolerance |
| 3–6, 10–13 | 1B1–1B4, 2B1–2B4 | B-side bidirectional I/O terminals - connect to peripheral buses, sensors, or memory banks; rail-to-rail voltage swing support |
| 7, 9 | 1A, 2A | A-side bidirectional I/O terminals - serve as common signal ports routed to microcontroller GPIOs, ADC inputs, or DAC outputs |
| 8 | GND | Ground reference - low-impedance return path for switch current and logic control; decoupling capacitor required near VCC pin |
| 16 | VCC | Supply voltage input - powers internal logic and switch driver; requires local 100 nF ceramic bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 1-of-4 mux/demux | Enables concurrent routing of two separate data streams (e.g., camera + radar sensor data) using shared address lines |
| 5 Ω typical ON-resistance | Minimizes insertion loss and signal distortion in analog video, audio, and high-speed digital traces up to 302 MHz |
| IOFF partial power-down | Prevents reverse current flow when VCC is off but I/O lines remain live - critical for fail-safe operation in domain controller architectures |
| Rail-to-rail analog switching | Supports full VCC-to-GND signal swing without clipping - suitable for unbuffered sensor outputs and legacy analog interfaces |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from -40 °C to +125 °C ambient - meets requirements for powertrain, chassis, and ADAS ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 1-of-4 bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBT3253QPWRQ1 | Higher ON-resistance (7 Ω typ at 3.3 V), wider supply range (4.5 V–5.5 V), no IOFF circuitry | Requires external power sequencing for safe hot-swap; limited to 5 V systems only | Select only if 5 V compatibility is mandatory and partial power-down is not required |
| 74LVC1G3157DP-Q100 | Single-channel SPDT switch, lower integration density, 6 Ω RON, same AEC-Q100 Grade 1 rating | Requires two devices to match dual 1-of-4 functionality; increases board space and routing complexity | Choose when space constraints allow discrete channel expansion and design favors modular scalability |
Compared with SN74CBT3253QPWRQ1 and 74LVC1G3157DP-Q100, the 74CBTLV3253D-Q100 delivers superior signal fidelity (4.0 Ω RON), built-in IOFF protection for mixed-power-domain systems, and native 2.3–3.6 V operation - making it optimal for modern 3.3 V automotive domain controllers requiring compact, robust, and low-distortion signal routing.

FAQ
What is the maximum signal frequency supported by the 74CBTLV3253D-Q100?
The device supports up to 302 MHz (-3 dB bandwidth) when configured in ON-state with 50 Ω load and 3.3 V supply, as verified by measurement per Figure 17 in the datasheet. This makes it suitable for high-speed digital interfaces like MIPI D-PHY clock lanes and LVDS pixel clocks, provided trace impedance and layout parasitics are controlled.
How should the output enable (OE) pins be handled during power-up?
Both 1OE and 2OE must be held HIGH via external pull-up resistors during power-up and power-down to ensure all switches remain in high-impedance OFF-state. The minimum resistor value is determined by the current-sinking capability of the OE input - typically 10 kΩ to VCC suffices for most automotive applications with <100 µA leakage.
Does the 74CBTLV3253D-Q100 support analog signal switching?
Yes - it provides rail-to-rail analog switching capability with 5 Ω typical ON-resistance and <20 pF ON-state capacitance, enabling distortion-free transmission of analog video, audio, and sensor signals within the 0 V to VCC range. Its CMOS architecture ensures symmetrical turn-on/turn-off characteristics for bidirectional analog paths.
Can this device be used in hot-swap applications?
Yes - the integrated IOFF circuitry actively disables all switches and limits power-off leakage to ±10 µA when VCC = 0 V, preventing damaging back-current flow from live I/O lines into the unpowered device. This satisfies hot-swap requirements in modular automotive ECUs and diagnostic tools per ISO 11898-2 and J1939-14.
