Product details
Overview
74CBTLV3253QG8 from Renesas Electronics is a low-voltage dual 1-of-4 multiplexer/demultiplexer IC with bi-directional 5Ω switches, operating from 2.3V to 3.6V supply, supporting industrial temperature range (−40°C to +85°C), and housed in a 16-pin QSOP package. It enables high-speed signal routing in compact digital systems requiring minimal propagation delay and power-off isolation.
For engineers reviewing the 74CBTLV3253QG8 datasheet, 74CBTLV3253QG8 pinout, 74CBTLV3253QG8 application, or 74CBTLV3253QG8 equivalent, key selection criteria include on-state resistance (≤8Ω typical), propagation delay (≤0.25ns), OE-controlled high-impedance state, over-voltage tolerance, and QSOP package compatibility with space-constrained PCB layouts.
Technical Context
The 74CBTLV3253QG8 implements two independent 1:4 analog/digital multiplexer/demultiplexer banks, each controlled by S0/S1 select lines and individual output-enable (1OE/2OE) inputs. Its CMOS-based switch architecture delivers rail-to-rail signal handling with no DC bias requirement.
Each switch exhibits 5Ω typical on-resistance at VCC = 3.3V and IO = 24mA, supports bidirectional signal flow, and maintains channel isolation when powered down (IOFF ≤ 50µA). Control inputs tolerate voltages up to 4.6V regardless of VCC level.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3V to 3.6V - Enables direct interface with 2.5V and 3.3V logic families without level shifters. |
| RON (Typ.) | 5Ω at VCC = 3V, IO = 24mA - Ensures minimal insertion loss and signal distortion for high-fidelity analog/digital switching. |
| tPD (Max) | 0.25ns - Supports sub-nanosecond timing-critical applications such as high-speed bus gating and test access routing. |
| IOFF (Max) | 50µA at VCC = 0V - Guarantees robust channel isolation during power sequencing or hot-swap conditions. |
| VI/O Tolerance | −0.5V to +4.6V - Allows safe interfacing with higher-voltage peripherals without external protection circuitry. |
| Operating Temp | −40°C to +85°C - Qualified for industrial control, motor drives, and factory automation environments. |
| ESD Rating | >2000V HBM, >200V MM - Reduces susceptibility to handling damage during assembly and field operation. |
Pinout & Package
74CBTLV3253QG8 is packaged in a 16-pin Quarter-Size Small Outline Package (QSOP, PCG16), 3.9mm × 4.9mm body, 1.27mm pitch, with exposed pad not present. Pin numbering follows standard top-view orientation with Pin 1 marked by notch or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15, 16 | GND, VCC, 1OE | Ground reference, supply input, and first bank output enable - tying 1OE to VCC via pullup ensures power-up high-Z state. |
| 2, 3, 4, 5 | 1B1–1B4 | First bank B-side data terminals - bidirectional I/O ports connected to selected channel when 1OE = LOW and S0/S1 decoded. |
| 6, 7, 9, 10 | 2B1–2B4 | Second bank B-side data terminals - independently controlled by 2OE, S0, S1; electrically isolated from Bank 1. |
| 11, 14 | 1A, 2A | A-side common ports - serve as multiplexed inputs (mux mode) or demultiplexed outputs (demux mode) per bank. |
| 12, 13 | S0, S1 | Binary select inputs - determine active B-port (1B1–1B4 or 2B1–2B4) per bank; L/L selects B1, H/H selects B4. |
| 8 | 2OE | Second bank output enable - active LOW; must be pulled HIGH during power-up to prevent unintended conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional 5Ω Switch | Enables transparent signal routing in either direction without polarity constraints, ideal for shared bus architectures. |
| Power-Off Isolation | IOFF ≤ 50µA ensures no leakage path between A and B ports when VCC = 0V, critical for system-level power management. |
| Over-Voltage Tolerance | VI/O rated −0.5V to +4.6V allows safe connection to 5V-tolerant signals even when VCC = 2.5V, eliminating external clamping diodes. |
| Industrial Temp Support | Guaranteed operation from −40°C to +85°C meets EN 60068-2 environmental stress requirements for industrial deployment. |
| Low Propagation Delay | tPD ≤ 0.25ns minimizes timing skew in high-speed clock/data gating, supporting >1GHz effective switching rates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 1-of-4 multiplexer/demultiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBTLV3253PWR | TSSOP-16 package (PGG16); identical electrical specs and pinout; RoHS-compliant tape-and-reel delivery. | No thermal or mechanical differentiation; same industrial temp support and switching performance. | Select when automated SMT placement and volume procurement require TSSOP packaging and reel format. |

FAQ
What is the maximum continuous current rating per channel of the 74CBTLV3253QG8?
The 74CBTLV3253QG8 supports a continuous channel current of 128mA per switch, verified under DC conditions with VCC = 3.3V and ambient temperature at 25°C. This rating applies to both directions of signal flow and remains valid across the full industrial temperature range when derated per thermal limits specified in the datasheet's absolute maximum ratings table.
Does the 74CBTLV3253QG8 support hot-swap or live-insertion scenarios?
Yes, the 74CBTLV3253QG8 supports hot-swap operation due to its over-voltage tolerant I/O pins (−0.5V to +4.6V), power-off isolation (IOFF ≤ 50µA), and latch-up immunity exceeding 100mA. These features prevent damage or unintended conduction when inserted into a live backplane or when peripheral voltages are applied before VCC stabilization.
Can the 74CBTLV3253QG8 be used to route analog signals such as audio or sensor outputs?
Yes, the 74CBTLV3253QG8 is suitable for analog signal routing including audio, thermocouple, and resistive sensor outputs due to its 5Ω typical on-resistance, rail-to-rail voltage handling, and bidirectional operation. Its low RON and minimal charge injection ensure minimal THD and signal attenuation, provided source/load impedances remain within recommended drive capability limits.
What is the recommended pull-up resistor value for 1OE and 2OE on the 74CBTLV3253QG8?
The datasheet recommends tying 1OE and 2OE to VCC through a pullup resistor whose minimum value is determined by the current-sinking capability of the driving source. For standard CMOS drivers, a 10kΩ resistor is commonly used; lower values (e.g., 4.7kΩ) improve noise immunity but increase static current draw - always verify against the driver's VOH/IOL specifications.
Is the 74CBTLV3253QG8 pin-compatible with the QS3253 device?
Yes, the 74CBTLV3253QG8 is functionally equivalent to the QS3253 and shares identical pin configuration, electrical behavior, and functional block diagram. Both devices use the same 16-pin QSOP/TSSOP footprint and support identical control logic, making the 74CBTLV3253QG8 a drop-in replacement for QS3253 in existing designs without layout changes.
