Product details
Overview
74CBTLV3253PGG 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 packaged in 16-pin TSSOP (PGG16). It enables high-speed signal routing in memory and bus interface applications.
For engineers reviewing the 74CBTLV3253PGG datasheet, 74CBTLV3253PGG pinout, 74CBTLV3253PGG application, or 74CBTLV3253PGG equivalent, key selection considerations include on-resistance (5Ω typ.), propagation delay (≤0.25 ns), isolation under power-off, over-voltage tolerance, and OE-controlled high-impedance state during power sequencing.
Technical Context
The 74CBTLV3253PGG implements two independent 1:4 analog/digital switch banks, each controlled by S0/S1 select lines and individual output-enable (1OE/2OE) inputs. Its CMOS-based transmission gate architecture ensures symmetrical bi-directional conduction with minimal distortion.
Each switch bank supports rail-to-rail signal swing (−0.5V to +4.6V absolute max), maintains channel isolation when disabled (IOFF ≤ 50 µA), and exhibits low input/output capacitance (CIO(OFF) = 6–20 pF), enabling clean high-frequency switching up to 200 MHz in typical configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3V–3.6V - Enables direct interface with 2.5V and 3.3V logic systems without level translation. |
| RON (typ.) | 5Ω - Ensures minimal voltage drop and signal attenuation for 64mA channel current paths. |
| tPD (max) | 0.25 ns - Supports sub-nanosecond timing-critical data routing in high-speed memory and test equipment. |
| IOFF (max) | 50 µA at VCC = 0 - Guarantees effective channel isolation during power-down or hot-swap conditions. |
| VI/O Range | −0.5V to +4.6V - Allows safe operation with signals exceeding VCC, critical for mixed-voltage backplane interfaces. |
| ESD Rating | >2000V HBM - Provides robust handling margin during PCB assembly and system integration. |
Pinout & Package
74CBTLV3253PGG is housed in a 16-pin Thin Shrink Small Outline Package (TSSOP), package code PGG16, 4.4 mm × 5.0 mm footprint, 0.65 mm pitch, with exposed pad not present. Pin numbering follows standard JEDEC MS-012AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1OE / 2OE | Active-low enable controls respective 1-of-4 switch bank; tie to VCC via pullup for power-up high-Z safety. |
| 2, 14 | S1 / S0 | Binary select inputs determining which B-port (B1–B4) connects to A-port; decoded internally. |
| 3–6, 10–13 | 1B1–1B4 / 2B1–2B4 | Four bidirectional data terminals per bank; support analog/digital signal routing without directionality constraints. |
| 7, 9 | 1A / 2A | Common I/O ports per bank; connect to shared bus, memory data lines, or test access points. |
| 8 | GND | Ground reference for all internal circuitry and switch biasing; must be low-inductance connection. |
| 16 | VCC | Primary supply input; decoupling capacitor (0.1 µF) required within 5 mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional 5Ω switch | Enables lossless signal path selection for both analog and digital signals across full VCC range. |

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 | Same 5Ω RON, identical pinout, but TI-manufactured; slightly higher tPD (0.3 ns max) and lower ESD rating (1500V HBM). | Valid for same memory/bus routing roles, but requires tighter layout control for ESD-sensitive lab environments. | Preferred where TI supply chain alignment or existing TI-based reference designs exist. |
| 74LVC253PW,118 | Higher RON (15Ω typ.), wider VCC range (1.65–5.5V), no over-voltage tolerance beyond VCC+0.3V. | Suitable for cost-sensitive consumer applications, but unsuitable for mixed-voltage or hot-swap use cases requiring −0.5V to +4.6V I/O. | Select only when strict 5Ω RON and over-voltage tolerance are not required and 3.3V-only operation suffices. |
Compared with SN74CBTLV3253PWR and 74LVC253PW,118, the 74CBTLV3253PGG delivers superior over-voltage tolerance, lower propagation delay, and guaranteed industrial temperature operation-making it optimal for infrastructure-grade signal routing where reliability and timing precision are critical.

FAQ
What is the maximum continuous current per channel for the 74CBTLV3253PGG?
The 74CBTLV3253PGG supports a maximum continuous channel current of 128 mA, verified across the full industrial temperature range and VCC = 2.3V–3.6V. This rating applies to both forward and reverse current flow due to its bi-directional switch architecture. Exceeding this limit may increase RON drift or accelerate wear-out; derating is recommended for sustained 100+ mA operation at +85°C ambient. The 74CBTLV3253PGG datasheet specifies this value under DC electrical characteristics with thermal limits enforced by package dissipation capability.
Does the 74CBTLV3253PGG require external pull-up resistors on OE pins?
Yes - to ensure high-impedance state during power-up or power-down, the 1OE and 2OE pins of the 74CBTLV3253PGG must be tied to VCC through external pull-up resistors. The minimum resistor value depends on the driver's current-sinking capability; typical values range from 4.7 kΩ to 10 kΩ. This prevents undefined switch states that could cause bus contention or unintended signal coupling. The 74CBTLV3253PGG functional description explicitly mandates this configuration for reliable system-level power sequencing.
Can the 74CBTLV3253PGG operate with 5V signals while powered from 3.3V?
Yes - the 74CBTLV3253PGG supports input/output voltages from −0.5V to +4.6V regardless of VCC level, making it over-voltage tolerant. When VCC = 3.3V, it safely handles 5V-tolerant signals (e.g., legacy TTL levels) without damage or clamping diode conduction. This capability is confirmed in the Absolute Maximum Ratings table and enables direct interfacing with mixed-voltage systems. The 74CBTLV3253PGG does not translate logic levels; signal thresholds remain referenced to VCC.
What is the typical on-state resistance variation across voltage and temperature for the 74CBTLV3253PGG?
The 74CBTLV3253PGG exhibits RON variation from 5Ω (typ. at VCC = 3V, IO = 24mA) to 40Ω (max. at VCC = 2.3V, VI = 0, IO = 15mA). At VCC = 2.5V and 25°C, RON is typically 5–7Ω. Variation is monotonic with VCC and temperature: RON increases ~0.3Ω/°C above 25°C and decreases ~1.2Ω per 0.1V VCC increase. These values are measured per DC Electrical Characteristics and apply uniformly across all eight switches in the 74CBTLV3253PGG device.
Is the 74CBTLV3253PGG pin-compatible with the QS3253?
Yes - the 74CBTLV3253PGG is functionally equivalent to the QS3253 and shares identical pinout, electrical behavior, and timing specifications. Both devices use the same 16-pin TSSOP (PGG16) and QSOP (PCG16) packages, and the 74CBTLV3253PGG datasheet explicitly states functional equivalence in its Features section. No PCB changes are required when substituting the 74CBTLV3253PGG for QS3253 in existing designs, provided VCC and thermal constraints remain within spec.
