Product details
Overview
74CB3Q3257PW-Q100 from Nexperia is a quad 1-of-2 FET bus switch with integrated charge pump, functioning as a high-bandwidth analog multiplexer/demultiplexer in automotive signal routing applications. It supports 0 V to 5 V signal switching at VCC = 3.3 V, delivers 4 Ω typical ON resistance, 3.5 pF OFF-state capacitance, and operates across -40 °C to +85 °C.
For engineers reviewing the 74CB3Q3257PW-Q100 datasheet, 74CB3Q3257PW-Q100 pinout, 74CB3Q3257PW-Q100 application, or 74CB3Q3257PW-Q100 equivalent, key selection criteria include overvoltage switching capability, IOFF partial power-down support, AEC-Q100 Grade 3 qualification, and TSSOP16 package compatibility with high-density PCB layouts.
Technical Context
This device implements four independent SPDT analog switches using NMOS pass transistors enhanced by an internal charge pump that elevates gate drive voltage above VCC. The architecture enables rail-to-rail analog signal handling (0 V to 5 V) while powered from 2.3 V–3.6 V supplies, eliminating level-shifter requirements in mixed-voltage systems.
Each channel features active-Low OE control and single-pole double-throw (1-of-2) selection via S input, with propagation delays under 5.5 ns (VCC = 3.0–3.6 V) and disable times under 6.0 ns. IOFF leakage remains ≤±1 μA at VCC = 0 V, supporting live insertion and hot-swap operation without back-driving powered subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.3 V to 3.6 V - Enables direct interface with 2.5 V/3.3 V logic domains without external regulators. |
| Signal Switching Range | 0 V to 5 V - Allows bidirectional analog/digital signal routing between 5 V sensors and 3.3 V microcontrollers. |
| ON Resistance (RON) | 4 Ω typical at VCC = 3.3 V - Minimizes voltage drop and signal attenuation in high-speed data paths. |
| OFF-State Capacitance | 3.5 pF typical - Reduces crosstalk and maintains signal integrity in multi-channel multiplexed buses. |
| Bandwidth | 0.5 GHz maximum - Supports high-frequency signals including USB 2.0, I²C fast-mode+, and sensor interfaces. |
| Switching Frequency | 20 MHz maximum - Enables rapid channel reconfiguration for time-division multiplexing of multiple sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FET multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3USB30E-Q1 | Single-channel 2:1 USB 2.0 switch; no charge pump; RON = 6 Ω typical; supports only 3.3 V signaling. | Limited to USB data lines; lacks 5 V overvoltage tolerance and quad-channel integration. | Select when only one high-speed USB path requires isolation and board space permits discrete channel implementation. |
| SN74CBT3257QPWRQ1 | Quad 1-of-2 switch without charge pump; RON = 7 Ω typical; requires VCC ≥ 4.5 V for 5 V signal handling. | Cannot operate from 3.3 V supply while switching 5 V signals; higher RON increases insertion loss. | Choose only if system uses 5 V logic rails and thermal budget allows higher power dissipation from elevated RON. |
Compared with TS3USB30E-Q1 and SN74CBT3257QPWRQ1, the 74CB3Q3257PW-Q100 uniquely combines quad-channel density, 3.3 V supply operation with 5 V signal tolerance, and AEC-Q100 Grade 3 qualification-enabling single-component replacement of multiple discrete switches in space-constrained automotive modules.

FAQ
What is the maximum signal voltage this device can switch when powered at 3.3 V?
The 74CB3Q3257PW-Q100 supports 0 V to 5 V analog/digital signal switching with VCC = 3.3 V, enabled by its internal charge pump that boosts NMOS gate voltage beyond VCC. This eliminates the need for external level shifters when interfacing 5 V sensors or actuators with 3.3 V microcontrollers in automotive domains.
Does this part support partial power-down operation?
Yes, the device supports IOFF partial power-down mode: when VCC = 0 V, leakage current per I/O pin remains ≤±1 μA even with 0 V to 5.5 V applied to switch terminals. This prevents back-driving powered subsystems and enables safe hot-swap functionality in modular automotive ECUs.
How does the charge pump improve performance compared to standard bus switches?
The integrated charge pump raises the gate voltage of the NMOS pass transistors above VCC, resulting in lower and flatter ON resistance (4 Ω typical) across the full 0–5 V signal range. This improves signal fidelity, reduces distortion in analog sensor paths, and enables reliable 5 V signal switching from 3.3 V supplies without body diode conduction.
Is this device qualified for automotive use, and what grade applies?
Yes, the 74CB3Q3257PW-Q100 is qualified to AEC-Q100 Grade 3, specifying operation from -40 °C to +85 °C ambient temperature and passing rigorous stress tests for automotive applications. It is intended for use in engine control, body electronics, and ADAS modules-not safety-critical systems like airbag controllers unless separately validated.
