Product details
Overview
74CBTLV3253PGG8 from Renesas Electronics is a low-voltage dual 1-of-4 multiplexer/demultiplexer IC with bi-directional 5Ω switches, 2.3V–3.6V supply operation, −40°C to +85°C industrial temperature range, and TSSOP-16 package. It enables high-speed signal routing in FPGA I/O expansion, memory address selection, and test access multiplexing.
For engineers reviewing the 74CBTLV3253PGG8 datasheet, 74CBTLV3253PGG8 pinout, 74CBTLV3253PGG8 application, or 74CBTLV3253PGG8 equivalent, key selection criteria include on-resistance (5Ω typ), propagation delay (0.15–0.25 ns), isolation under power-off, over-voltage tolerance, and dual-bank independent enable control.
Technical Context
The 74CBTLV3253PGG8 implements two independent 1:4 analog/digital switch banks, each with dedicated S0/S1 select lines and OE enable. Each bank routes one A-port signal to one of four B-port channels (B1–B4) or vice versa, supporting bidirectional data flow without direction control.
Switch operation is governed by CMOS transmission-gate topology with rail-to-rail voltage handling (−0.5V to +4.6V), enabling interoperability across mixed-supply systems. Power-off isolation and latch-up immunity (>100 mA) ensure robustness during hot-swap and system initialization sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3V–3.6V - supports modern low-voltage logic domains including 2.5V and 3.3V systems |
| RON (typ) | 5Ω - minimizes insertion loss and signal distortion for high-fidelity analog/digital switching |
| tPD (max) | 0.25 ns - enables sub-nanosecond timing-critical routing in high-speed interface bridging |
| IOFF (max) | 50 µA at VCC = 0 - ensures signal isolation when powered down, preventing back-drive damage |
| VI/O Range | −0.5V to +4.6V - allows over-voltage tolerant operation beyond VCC, easing level-shifting design |

Pinout & Package
TSSOP-16 (PGG16) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad not present, RoHS-compliant green finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15, 16 | GND / VCC / 1OE | Ground reference, supply rail, and output-enable for Bank 1 - tie 1OE to VCC via pullup for safe power-up state |
| 2, 3, 4, 5 | 1B1–1B4 | Bank 1 bidirectional channel terminals - connect to peripheral signals requiring dynamic routing |
| 6, 7, 10, 11 | 2B1–2B4 | Bank 2 bidirectional channel terminals - operate independently from Bank 1 with separate S0/S1/2OE |
| 8, 14 | 1A / 2A | Common input/output ports per bank - serve as multiplexed data hubs for address/data buses |
| 9, 12, 13 | S0 / S1 / 2OE | Select address bits and Bank 2 enable - synchronous control allows glitch-free channel switching |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional 5Ω switch | Enables transparent signal coupling in both directions without polarity constraints or level translation |
| Power-off isolation | Maintains high-impedance between ports when VCC = 0, preventing unintended current paths during sequencing |

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 function, 5Ω RON, but TI package code PWR = TSSOP-16 with different thermal pad and moisture sensitivity level | Identical pinout and logic behavior; differs only in JEDEC packaging specs and tape/reel orientation | Drop-in replacement if moisture sensitivity and reflow profile match manufacturing process |
| 74LVC253PW,118 | Higher RON (15Ω typ), slower tPD (3.5 ns max), 1.65V–3.6V VCC - lower speed, higher power efficiency | Not suitable for sub-ns timing paths; better for cost-sensitive, lower-frequency logic routing | Select when nanosecond timing is unnecessary and wider VCC range or lower static current is prioritized |
Compared with SN74CBTLV3253PWR and 74LVC253PW,118, the 74CBTLV3253PGG8 delivers superior high-speed performance (0.25 ns tPD vs. 3.5 ns) and lower on-resistance (5Ω vs. 15Ω), making it optimal for timing-critical FPGA and memory interface applications where signal fidelity and latency are critical.

FAQ
What is the maximum operating voltage for the 74CBTLV3253PGG8?
The 74CBTLV3253PGG8 supports a supply voltage range of 2.3V to 3.6V for normal operation. Its absolute maximum ratings allow input/output voltages from −0.5V to +4.6V regardless of VCC, enabling over-voltage tolerant interfacing with higher-voltage peripherals without level shifters. This specification is confirmed in the Absolute Maximum Ratings table of the official Renesas datasheet DSC-5397/9.
Does the 74CBTLV3253PGG8 support bidirectional signal flow?
Yes, the 74CBTLV3253PGG8 supports fully bidirectional signal routing within each of its two independent 1:4 switch banks. The CMOS transmission-gate architecture imposes no directionality - signals pass equally well from A to B or B to A. This is verified in the Functional Block Diagram and Simplified Schematic sections, where no directional diodes or asymmetrical circuitry are present.
How does the 74CBTLV3253PGG8 behave during power-down?
During power-down (VCC = 0V), the 74CBTLV3253PGG8 maintains high-impedance isolation between all ports, with IOFF ≤ 50 µA. This prevents back-driving or leakage currents from live signal lines into unpowered subsystems. The datasheet explicitly states "Isolation under power-off conditions" as a core feature and confirms this behavior in the DC Electrical Characteristics table under IOFF test conditions.
What is the typical on-resistance of the 74CBTLV3253PGG8 switches?
The typical on-resistance (RON) of the 74CBTLV3253PGG8 switches is 5Ω, measured at VCC = 3V, IO = 24mA, and VI = 2.4V. This value is specified in the DC Electrical Characteristics table and applies across both banks. Lower RON reduces voltage drop and signal attenuation, making the 74CBTLV3253PGG8 suitable for analog and high-speed digital signal routing where impedance matching matters.
Is the 74CBTLV3253PGG8 pin-compatible with the QS3253?
Yes, the 74CBTLV3253PGG8 is functionally equivalent to the QS3253 and shares identical pinout, electrical behavior, and logic functionality. The datasheet explicitly states "Functionally equivalent to QS3253" in the Features section and confirms matching pin configuration and function table. Both devices use TSSOP-16 (PGG16) and QSOP-16 (PCG16) packages with identical terminal assignments.
