Product details
Overview
74CBTLV1G125GF,132 from Nexperia is a single high-speed CMOS bus switch with active-low output enable (OE), 5 Ω typical ON-resistance at 3.3 V, rail-to-rail signal switching, and IOFF partial power-down protection. It operates from 2.3 V to 3.6 V across –40 °C to +125 °C and is used in low-voltage data path isolation for portable computing and industrial I/O expansion.
For engineers reviewing the 74CBTLV1G125GF,132 datasheet, 74CBTLV1G125GF,132 pinout, 74CBTLV1G125GF,132 application, or 74CBTLV1G125GF,132 equivalent, key selection criteria include guaranteed sub-0.25 ns propagation delay at 3.3 V, <5 μA ICC supply current, Schmitt-trigger input tolerance for slow edges, IOFF leakage <10 μA during power-off, and compatibility with JEDEC JESD8-5/JESD8C voltage standards.
Technical Context
This device implements a bidirectional analog/digital signal switch controlled by a single active-low OE input. Its CMOS transmission gate architecture enables rail-to-rail operation on A and B ports without level-shifting, while the integrated IOFF circuit disables both ports when VCC = 0 V to block backflow current.
The Schmitt-trigger input on OE provides hysteresis (typ. 0.3 V) for noise immunity against slow-rising control signals, and the 5 Ω ON-resistance ensures minimal insertion loss for high-speed data lines up to 263 MHz (-3 dB bandwidth at 3.3 V/50 Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.3 V to 3.6 V - supports dual-voltage I/O domains in mixed-supply systems |
| ON-resistance (RON) | 4.2 Ω typ. at VCC = 3.0 V, ISW = 64 mA - enables low-loss signal routing for USB 1.1, I²C, and GPIO expansion |
| Propagation delay (tpd) | 0.16 ns typ. at VCC = 3.3 V - preserves signal integrity in >100 MHz digital buses |
| 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 - meets industrial-grade robustness requirements without external protection |
| Operating temperature | –40 °C to +125 °C - qualified for under-hood automotive modules and industrial PLCs |
| Switch capacitance (Csw) | 10.3 pF typ. (ON-state) - minimizes capacitive loading on high-impedance source drivers |
Pinout & Package
XSON6 package (SOT886): plastic extremely thin small outline, no leads, 6 terminals, body size 1.0 × 1.45 × 0.5 mm. Pin 1 index located at lower-left corner below marking code "bM".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output enable input | Active-low control: logic LOW connects A↔B; logic HIGH places both ports in high-Z state |
| 2 (A) | Data port A | Bidirectional I/O terminal - accepts/receives rail-to-rail signals from 0 V to VCC |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry and switch current; must be low-impedance |
| 4 (B) | Data port B | Bidirectional I/O terminal - electrically identical to A; fully symmetrical switch path |
| 5 (n.c.) | No-connect terminal | Internally unconnected; must remain floating - no PCB trace or solder mask opening required |
| 6 (VCC) | Supply voltage | Primary power rail (2.3–3.6 V); powers internal logic and switch driver; decoupling capacitor mandatory |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports full 0 V to VCC signal swing on A/B ports - eliminates need for level shifters in mixed-voltage interconnects |
| IOFF partial power-down | Blocks current flow between A and B when VCC = 0 V - enables safe live-insertion in modular backplanes and hot-plug peripherals |
| Schmitt-trigger OE input | Input hysteresis ≥0.3 V - tolerates slow-rising enable signals from microcontrollers or RC networks without oscillation |
| Low ON-resistance flatness | RON variation <±2 Ω over 0–3.3 V input range - maintains consistent signal attenuation across logic levels |
| JEDEC-compliant voltage interface | Validated per JESD8-5 (2.3–2.7 V) and JESD8C (2.7–3.6 V) - ensures interoperability with legacy and next-gen logic families |
Applications
| USB 1.1 Data Line Isolation | I²C Bus Multiplexing |
|---|---|
|
Use Scenario: Isolating D+ and D− lines between host controller and peripheral port during enumeration or fault recovery. IC Role / Device Role / Timing Role: Bidirectional analog switch enabling/disabling USB signal path under firmware control via OE. Use Value: Prevents bus contention during hot-plug events; 5 Ω RON adds <0.1 dB insertion loss at 12 MHz, preserving USB 1.1 eye diagram integrity. |
Use Scenario: Expanding a single I²C master to drive multiple slave address domains using time-multiplexed channel selection. IC Role / Device Role / Timing Role: Low-capacitance (10.3 pF) bidirectional switch isolating SDA/SCL segments during arbitration. Use Value: Enables 400 kHz operation with <10 ns added propagation delay; IOFF blocks cross-talk when channels are disabled. |
| GPIO Expansion Interface | Industrial Sensor Signal Routing |
|
Use Scenario: Sharing limited MCU GPIO pins among multiple sensors or actuators via software-controlled signal gating. IC Role / Device Role / Timing Role: High-speed, low-leakage switch connecting sensor outputs to ADC inputs only when sampled. Use Value: Reduces system standby current by blocking leakage paths; Schmitt-trigger OE allows direct connection to open-drain GPIOs. |
Use Scenario: Routing analog outputs from multiple pressure/temperature transducers to a shared signal conditioning chain in PLC modules. IC Role / Device Role / Timing Role: Rail-to-rail analog switch handling 0–3.3 V sensor outputs without clipping or distortion. Use Value: 5 Ω RON introduces <0.02% gain error at 10 kΩ load; –40 °C to +125 °C rating matches industrial ambient requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBTLV1G125DBVR | Same 5-pin SOT-23 package; 6.5 Ω max RON at 3.3 V (vs. 7 Ω max for 74CBTLV1G125GF,132); higher ICC (20 μA vs. 10 μA) | Higher thermal resistance (210 K/W vs. 190 K/W) limits continuous current in compact layouts | Select for legacy SOT-23 footprint compatibility where board space permits slightly higher ON-resistance |
| 74LVC1G3157GW,125 | Lower VCC range (1.65–5.5 V); 8 Ω max RON at 3.3 V; no IOFF circuitry | Lacks power-off isolation - unsuitable for partial-power-down systems requiring backflow prevention | Choose for wider supply flexibility in non-hot-swap designs where IOFF is not required |
Compared with SN74CBTLV1G125DBVR and 74LVC1G3157GW,125, the 74CBTLV1G125GF,132 delivers superior power-down safety (IOFF), lower static current, and tighter RON matching - making it optimal for thermally constrained, hot-pluggable industrial interfaces.

FAQ
What is the maximum recommended operating frequency for the 74CBTLV1G125GF,132?
The device supports signal switching up to 263 MHz (–3 dB bandwidth at 3.3 V with 50 Ω load), verified per Figure 11 test circuit. For digital logic applications, propagation delay of 0.25 ns max ensures reliable operation at data rates exceeding 100 MHz, provided PCB layout minimizes trace inductance and maintains controlled impedance.
Can the 74CBTLV1G125GF,132 be used with 1.8 V logic systems?
No - the absolute minimum supply voltage is 2.3 V per Table 6, and VIH/VIL thresholds are specified only for 2.3–3.6 V operation. At 1.8 V, the OE input lacks sufficient noise margin, and RON increases significantly (>15 Ω), degrading signal integrity. Use 74LVC1G3157 or similar 1.65 V–5.5 V switches instead.
Is a pull-up resistor required on the OE pin during power-up?
Yes - to guarantee high-impedance OFF-state during VCC ramp-up, OE must be held HIGH via a pull-up to VCC. The datasheet specifies current-sinking capability determines minimum resistor value; for typical 20 μA sink, a 100 kΩ resistor suffices. This prevents unintended A-B conduction before firmware initializes OE.
Does the 74CBTLV1G125GF,132 support hot-swap operation in backplane applications?
Yes - its IOFF circuit actively disables the switch and limits leakage to ±10 μA when VCC = 0 V, preventing backflow current from live backplane rails into unpowered slots. This meets IEC 61000-4-2 Level 3 ESD robustness and enables safe insertion/removal in modular industrial systems.
