Product details
Overview
74CBTLV3245PW-Q10J from Nexperia is an automotive-qualified 8-bit bidirectional bus switch with active-low output enable (OE), rail-to-rail switching, 5 Ω typical ON-resistance at 3.3 V, IOFF partial power-down protection, and operation from −40 °C to +125 °C. It routes high-speed digital signals between A- and B-port data lines in automotive infotainment backplanes and ADAS sensor interface buses.
For engineers reviewing the 74CBTLV3245PW-Q10J datasheet, 74CBTLV3245PW-Q10J pinout, 74CBTLV3245PW-Q10J application, or 74CBTLV3245PW-Q10J equivalent, this device supports low-latency signal routing in hot-swap-capable systems requiring AEC-Q100 Grade 1 qualification, sub-0.3 ns propagation delay, and <10 μA IOFF leakage at 0 V supply.
Technical Context
This device implements eight independent analog/digital transmission gates controlled by a single OE input. Each switch exhibits CMOS-compatible rail-to-rail voltage handling (0 V to VCC), Schmitt-triggered OE input for noise immunity, and IOFF circuitry that disables all channels and blocks backflow current when VCC = 0 V.
Its dynamic behavior is defined by propagation delay ≤0.31 ns (VCC = 3.6 V), enable/disable times ≤8.5 ns, and −3 dB bandwidth of 406 MHz (RL = 50 Ω, VCC = 3.3 V), enabling use in DDR clock distribution and high-speed serial sideband routing where signal integrity must be preserved across voltage domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.3 V to 3.6 V - Enables direct interfacing with 2.5 V and 3.3 V logic families without level translation. |
| ON resistance (RON) | Typ. 4.0 Ω at VCC = 3.3 V, ISW = 64 mA - Ensures minimal voltage drop and signal attenuation in high-current data paths. |
| Propagation delay (tpd) | Max 0.31 ns at VCC = 3.6 V - Supports >1 GHz signal edge rates in timing-critical interconnects. |
| IOFF leakage | ±50 μA at VCC = 0 V, VI/VO = 0–3.6 V - Prevents destructive backfeed during system power sequencing or hot-plug events. |
| Operating temperature | −40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and cockpit electronics. |
| ESD protection | HBM >2000 V, CDM >1000 V - Sustains assembly handling and field operation in automotive manufacturing environments. |
| Switch capacitance (ON) | 14.3 pF - Limits capacitive loading on high-speed buses, preserving rise/fall time integrity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74CBTLV3245BQ-Q100 | DHVQFN20 package (2.5 × 4.5 × 0.85 mm); lower thermal resistance (40 K/W vs. 65 K/W); no leads, side-wettable flanks. | Better suited for space-constrained, thermally demanding modules like radar front-ends where board area and heat dissipation are critical. | Select BQ for new designs prioritizing miniaturization and thermal performance; PW remains optimal for legacy TSSOP footprints and AOI compatibility. |
| SN74CBT3245QPWRQ1 | Texas Instruments part; 5.5 V max VCC; higher RON (6 Ω typ); wider temp range (−40 °C to +125 °C); different pinout (OE on pin 1). | Compatible in function but requires PCB redesign due to pin mismatch and lacks side-wettable flanks for AOI. | Use only if TI supply chain alignment is mandatory; verify layout changes for OE placement and thermal pad connection. |
Compared with 74CBTLV3245BQ-Q100, the PW variant offers proven AOI support and easier rework; versus SN74CBT3245QPWRQ1, it delivers lower RON, tighter propagation delay, and native AEC-Q100-aligned pinout-making it preferable for new automotive signal-routing designs where precision timing and manufacturability are prioritized.

FAQ
Can 74CBTLV3245PW-Q10J operate with 1.8 V logic levels?
No. The device requires VCC between 2.3 V and 3.6 V and does not support 1.8 V supply or input thresholds. Its VIH minimum is 1.7 V at VCC = 2.3–2.7 V and 2.0 V at VCC = 3.0–3.6 V, making it incompatible with 1.8 V core logic without level shifting.
Does the IOFF feature work when only one port is biased?
Yes. IOFF activates whenever VCC = 0 V, regardless of voltage applied to A or B ports. The specification guarantees ±50 μA maximum leakage with VI or VO = 0–3.6 V and VCC = 0 V, preventing backfeed even if one side remains energized.
Is the OE pin 5 V tolerant?
No. OE is not 5 V tolerant. Input voltage must remain within 0 V to VCC (max 3.6 V). Exceeding VCC risks latch-up or permanent damage, as confirmed by limiting values specifying VI max = VCC + 0.5 V only under transient conditions-not steady-state operation.
How does the Schmitt-trigger on OE improve system robustness?
The Schmitt-trigger provides hysteresis (typ. 0.3–0.5 V) on the OE input, rejecting noise spikes and slow-rising control signals. This eliminates false switching during power ramp-up or in electrically noisy automotive environments where GPIO edges may degrade over harness length or connector contact resistance.
