Frequently Asked Questions
How does the SN74CBTD3861DGVR support mixed 3.3V and 5V logic?
The SN74CBTD3861DGVR uses FET-based switching that tolerates supply voltages from 3.3V to 5V on each port independently. Its integrated diodes clamp bus voltage, allowing direct connection between 3.3V and 5V logic without level-shift circuitry.
What is the typical ON-resistance of the SN74CBTD3861DGVR and why does it matter?
Typical ON-resistance is around 5–10Ω, which minimizes signal degradation and power dissipation across the switch. Lower RON is critical in high-speed data buses to maintain signal integrity and reduce propagation delay.
Which package does SN74CBTD3861DGVR use and what is the pin count?
It comes in a 24-pin TSSOP (Thin Shrink Small-Outline Package) with 0.65mm pitch, making it well-suited for space-constrained PCB layouts in portable and embedded applications.
What are common substitutes or alternatives for SN74CBTD3861DGVR?
Compatible alternatives include the SN74CBT3861 (5V-only variant), SN74CBTLV3861 (1.8V/2.5V low-voltage version), and NXP 74CBTD3861 which shares pin-compatible TSSOP-24 footprint and equivalent bus switch functionality.
Is SN74CBTD3861DGVR RoHS compliant and suitable for lead-free assembly?
Yes, the DGVR suffix denotes a lead-free, RoHS-compliant package. It is compatible with standard lead-free soldering processes (SAC305 alloy) and meets environmental compliance requirements for export markets.
