Product details
Overview
74CBTLV6800PGG from Renesas Electronics is a low-voltage 10-bit bus switch IC with precharged outputs, designed for high-speed 3.3V bus isolation and live-insertion noise suppression. It features 5Ω on-state resistance, 2.3V–3.6V supply range, industrial temperature operation (−40°C to +85°C), and bi-directional A/B switching controlled by a single OE input.
For engineers reviewing the 74CBTLV6800PGG datasheet, 74CBTLV6800PGG pinout, 74CBTLV6800PGG application, or 74CBTLV6800PGG equivalent, key selection criteria include precharge-enabled B-port biasing (BIASV), power-off isolation, over-voltage tolerance, and TSSOP-24 package compatibility in industrial bus architectures.
Technical Context
The 74CBTLV6800PGG implements a single 10-bit bi-directional switch array with CMOS-compatible control logic and integrated 10-kΩ precharge path to BIASV. Its architecture enables deterministic high-impedance state during power sequencing when OE is tied to VCC via pull-up resistor.
Each switch exhibits low RON (5Ω typical at VCC = 3V), sub-0.25 ns propagation delay, and robust isolation (IOFF ≤ 50 µA at VCC = 0). The device supports live-insertion by precharging B-port to user-defined BIASV (1.3V to VCC), minimizing transient noise during hot-swap events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3V–3.6V - Enables direct interface with 2.5V/3.3V logic without level translation |
| RON | 5Ω typical - Minimizes voltage drop and signal distortion across active bus paths |
| tPD | 0.25 ns max at 3.3V - Supports >3 GHz effective bus switching rates in high-speed backplanes |
| BIASV Range | 1.3V to VCC - Allows configurable precharge level to match system reference or reduce ground bounce |
| IOFF | 50 µA max at VCC = 0 - Ensures true power-off isolation between A and B ports |
| ESD Rating | 2000V HBM / 200V MM - Meets industrial handling requirements without external protection |
| Operating Temp | −40°C to +85°C - Qualified for extended industrial environments without derating |
Pinout & Package
TSSOP-24 package (PGG24 code), 0.65 mm pitch, 7.8 mm × 4.4 mm body, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 | A1–A10 | Input/output port A - Bi-directional data path connected to upstream bus or controller |
| 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 | B1–B10 | Input/output port B - Bi-directional data path connected to downstream peripheral or slot |
| 21 | OE | Output enable - Active-low control; drives switch ON (A↔B) when low, OFF + B-precharge when high |
| 22 | BIASV | Bias voltage input - Sets precharge level for B-port during high-impedance state |
| 23 | VCC | Supply voltage - Powers internal logic and switch circuitry; must be decoupled locally |
| 24 | GND | Ground reference - Return path for all signals and supply current |
Key Features
| Feature | Design Value |
|---|---|
| Precharged B-port output | Reduces live-insertion transients by actively pulling B-lines to BIASV (not floating or weak-pull) |
| Power-off isolation | Maintains >1 MΩ isolation between A and B when VCC = 0, preventing backfeeding |
| Over-voltage tolerant I/O | Withstands −0.5V to +4.6V on A/B pins independent of VCC, enabling mixed-voltage interconnects |
| Low on-resistance matching | RON variation < ±1Ω across all 10 channels ensures uniform timing and skew control |
| Industrial latch-up immunity | Exceeds 100 mA per JEDEC JESD78, eliminating risk under ESD or surge stress |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBTLV6800PWR | Same 10-bit function, identical RON and timing, but TI's TSSOP-24 has different thermal pad layout and moisture sensitivity level (MSL3 vs MSL1) | Compatible in schematic; requires PCB footprint review due to thermal pad geometry and solder mask definition | Select when sourcing from TI-authorized channels or when legacy TI design reuse is required |
| 74CBTLV6800QG | Identical electrical specs and pinout, but QSOP-24 package (PCG24) - 1.0 mm pitch, 8.7 mm × 3.9 mm body, higher profile | Direct functional replacement; requires board-level mechanical validation for height clearance and connector alignment | Select when QSOP footprint already exists or when manual assembly/rework is prioritized over density |
Compared with SN74CBTLV6800PWR and 74CBTLV6800QG, the 74CBTLV6800PGG offers identical switching performance in a lower-profile, finer-pitch TSSOP package optimized for automated SMT lines and space-constrained industrial modules.

FAQ
What is the maximum allowable BIASV voltage for the 74CBTLV6800PGG?
The 74CBTLV6800PGG specifies BIASV range as 1.3V to VCC. With VCC up to 3.6V, BIASV may be set as high as 3.6V. Exceeding VCC risks forward-biasing internal protection diodes. For optimal precharge noise suppression in 3.3V systems, BIASV = 3.0V is commonly used and validated in Renesas application notes.
Does the 74CBTLV6800PGG require external pull-up resistors on OE?
Yes - to guarantee high-impedance state during power-up/power-down, OE must be pulled to VCC. Renesas recommends a 10 kΩ pull-up resistor, sized based on the driver's sink capability. Without it, OE may float, causing undefined switch states and potential bus contention during sequencing.
Can the 74CBTLV6800PGG operate reliably at 2.3V supply?
Yes - the 74CBTLV6800PGG is fully specified down to VCC = 2.3V. At this minimum, RON increases to 8Ω (max), tPD remains ≤0.15 ns, and IOFF stays ≤50 µA. All DC and AC parameters meet datasheet limits across the full −40°C to +85°C range at 2.3V.
Is the 74CBTLV6800PGG pin-compatible with the older QS3800 device?
Yes - the 74CBTLV6800PGG is functionally equivalent to QS3800 and shares identical pinout, electrical behavior, and package dimensions in TSSOP-24. Renesas explicitly states functional equivalence in the datasheet, enabling drop-in replacement where QS3800 was previously used.
What is the thermal resistance (θJA) of the 74CBTLV6800PGG in TSSOP-24 package?
Renesas specifies θJA = 120°C/W for the 74CBTLV6800PGG in standard JEDEC High-K board conditions (2S2P). With typical ICC < 10 µA and channel current < 128 mA, self-heating remains negligible (<0.1°C rise) under normal operation, making thermal derating unnecessary in most industrial layouts.
