Product details
Overview
TC7MBL3253CFK from Toshiba Electronic Devices & Storage Corporation is a dual 1-of-4 CMOS FET multiplexer/demultiplexer operating from 1.65 V to 3.6 V, featuring 9 Ω typical on-resistance at 3.0 V, 13 pF typical ON-capacitance, and high-impedance isolation when OE is high. It enables bidirectional signal routing in low-voltage digital interfaces such as USB 2.0 data switching and mobile baseband I/O expansion.
For engineers reviewing the TC7MBL3253CFK datasheet, TC7MBL3253CFK pinout, TC7MBL3253CFK application, or TC7MBL3253CFK equivalent, key selection criteria include its VSSOP16 package, sub-10 Ω RON, 6 ns enable/disable timing at 3.3 V, and power-down protection for all control inputs (OE, S1, S0) and I/O terminals.
Technical Context
The TC7MBL3253CFK integrates two independent 4:1 analog switches sharing common select (S1/S0) and output-enable (OE) inputs. Each switch supports bidirectional signal flow with rail-to-rail voltage handling (0 to VCC) and exhibits minimal propagation delay due to low RON–CI/O product.
Its power-down protection ensures input pins remain high-impedance during power-off conditions, preventing back-driving of upstream logic. The device operates across –40 °C to +85 °C and maintains stable RON and CI/O over its full 1.65–3.6 V supply range, making it suitable for battery-powered portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 3.6 V - supports single-supply operation in 1.8 V and 3.3 V logic domains without level translation. |
| RON (typ.) | 9 Ω @ VCC = 3.0 V - enables low-loss analog/digital signal routing with <100 mV voltage drop at 15 mA. |
| CI/O (ON) | 13 pF @ VCC = 3.0 V - minimizes signal distortion and crosstalk in high-speed data paths up to 100 MHz. |
| tPZL/tPLZ | 6 ns max @ VCC = 3.3 V - ensures fast channel enable/disable for dynamic reconfiguration in real-time I/O systems. |
| Operating Temp | –40 °C to +85 °C - qualified for industrial-grade embedded applications including handheld instrumentation and IoT edge nodes. |
| Input Leakage | ±1.0 µA max - reduces standby current and prevents false triggering in high-impedance sensor interface circuits. |
Pinout & Package
Package: VSSOP16 (US16), 3.0 mm × 4.4 mm, 0.5 mm pitch, 0.02 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable | Active-low global enable: drives all switches into high-Z state when high, overriding S1/S0. |
| 2 (S1), 3 (S0) | Select Inputs | Binary address lines selecting one of four Bn paths per mux; compatible with standard CMOS logic thresholds. |
| 4–7 (B1–B4) | Channel Outputs/Inputs | Four bidirectional switch terminals per mux; support analog/digital signals up to VCC. |
| 8 (GND) | Ground | Reference return path for all internal circuitry and switch conduction; must be low-inductance connection. |
| 9 (A1), 10 (A2) | Common Inputs/Outputs | Dual independent common ports - each connects to its respective B1–B4 bank under OE and S1/S0 control. |
| 11–14 (B1–B4) | Channel Outputs/Inputs | Second set of four bidirectional terminals for second mux; electrically isolated from first B-bank. |
| 15 (VCC) | Supply Voltage | Single positive supply input; decoupling capacitor (0.1 µF) required within 5 mm for noise immunity. |
| 16 (NC) | No Connect | Internally unconnected pin; must remain floating or grounded per layout best practices to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Low-Voltage Operation | Functional down to 1.65 V - enables direct integration with 1.8 V microcontrollers and LPDDR I/O without level shifters. |
| Power-Down Protection | Prevents back-current flow on OE, S1, S0, and I/O pins during power sequencing - eliminates need for external isolation diodes. |
| Bidirectional Switching | Supports signal flow in either direction between A and Bn - simplifies PCB routing in shared-bus architectures like camera module interfaces. |
| ESD Protection | Integrated HBM protection >2 kV on all pins - reduces external TVS requirements in compact portable designs. |
| Small Footprint | VSSOP16 package occupies 13.2 mm² area - ideal for space-constrained applications such as smartphone PMIC subsystems and wearable sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 1-of-4 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBT3253PWR | Higher RON (15 Ω typ. @ 3.3 V), wider VCC range (4.5–5.5 V), no power-down protection on I/O. | Requires level-shifting for 1.8 V systems; not suitable for battery-powered devices with aggressive power sequencing. | Choose when interfacing legacy 5 V logic or where higher drive strength outweighs leakage and size constraints. |
| 74LVC2G53DP | Single 2:1 mux (not dual 4:1), smaller X2SON8 package, lower RON (6 Ω typ.), but lacks shared S1/S0 and OE control. | Needs two ICs and additional logic to replicate TC7MBL3253CFK functionality - increases layout complexity and BOM count. | Prefer for ultra-low-power, space-limited designs where only one 2:1 path is needed per instance. |
Compared with SN74CBT3253PWR and 74LVC2G53DP, the TC7MBL3253CFK uniquely delivers dual 4:1 switching with unified control, sub-10 Ω RON, and integrated power-down protection - making it optimal for compact, low-voltage, dynamically reconfigurable I/O systems.

FAQ
What is the maximum signal voltage that can pass through the TC7MBL3253CFK switches?
The TC7MBL3253CFK supports rail-to-rail analog/digital signal switching from 0 V to VCC. With VCC rated up to 3.6 V, the maximum allowable signal voltage is 3.6 V peak-to-peak. Exceeding this violates the absolute maximum rating for switch I/O voltage (–0.5 V to VCC + 0.5 V), risking latch-up or permanent damage. Always ensure signal sources stay within the VCC domain of the TC7MBL3253CFK.
Does the TC7MBL3253CFK require external pull-up or pull-down resistors on its control inputs?
No, the TC7MBL3253CFK does not require external pull-up or pull-down resistors on OE, S1, or S0. Its CMOS inputs have defined VIH/VIL thresholds (0.7×VCC and 0.3×VCC) and internal protection circuits. However, unused control inputs must be tied to either VCC or GND per the datasheet to prevent floating states that could cause erratic switching or increased ICC.
Can the TC7MBL3253CFK be used in bidirectional USB 2.0 data line switching?
Yes, the TC7MBL3253CFK is suitable for bidirectional USB 2.0 D+/D– switching. Its 13 pF ON-capacitance, 9 Ω RON, and 6 ns enable/disable timing meet USB 2.0 full-speed (12 Mbps) and high-speed (480 Mbps) signal integrity requirements when properly terminated and routed. The device's low crosstalk and matched channel characteristics preserve differential signaling integrity.
What is the thermal resistance (θJA) of the TC7MBL3253CFK in its VSSOP16 package?
The TC7MBL3253CFK datasheet does not specify θJA for the US16 (VSSOP16) package. However, based on industry-standard VSSOP16 thermal models and its 180 mW maximum power dissipation rating, typical θJA is approximately 220 °C/W on a 1-layer JEDEC test board. For accurate thermal design, refer to Toshiba's application notes on VSSOP thermal layout or perform board-specific simulation using the device's 10 µA quiescent current and worst-case RON power loss.
Is the NC pin (Pin 16) on the TC7MBL3253CFK required to be left unconnected?
Yes, Pin 16 is designated NC (No Connect) and must remain unconnected - neither bonded nor wired internally. While grounding or leaving it floating is electrically permissible, Toshiba recommends leaving it unconnected to avoid unintended coupling or noise injection. PCB layout should omit any trace or pad connection to Pin 16 to maintain signal integrity and comply with the manufacturer's mechanical and electrical specifications for the TC7MBL3253CFK.
