Frequently Asked Questions
What is the maximum operating voltage for the 74CBT1G125DBVRG4?
The 74CBT1G125DBVRG4 operates with a supply voltage (VCC) range of 2.3V to 3.6V, making it compatible with 3.3V bus systems. It also supports 5V-tolerant inputs and outputs, allowing it to interface between 3.3V and 5V logic systems without additional level-shifting components.
What is the propagation delay of the 74CBT1G125DBVRG4 bus switch?
The 74CBT1G125DBVRG4 provides near-zero propagation delay, typically around 0.1ns, which is characteristic of CBT-series bus switches. This ultra-low delay is achieved because the device operates as a pass-gate switch rather than a buffered logic gate, making it ideal for high-speed bus switching applications.
How is the output enable (OE) pin used on the 74CBT1G125DBVRG4?
The 74CBT1G125DBVRG4 features an active-low output enable (OE#) pin. When OE# is driven LOW, the bus switch is enabled and the A and B ports are connected. When OE# is driven HIGH, the switch is disabled and both ports are placed in a high-impedance state, effectively isolating the connected buses.
What package does the 74CBT1G125DBVRG4 come in and what are its dimensions?
The 74CBT1G125DBVRG4 is packaged in a 5-pin SOT-23 (DBV) package with tape and reel (R4) packaging for automated assembly. The SOT-23 package is extremely compact, measuring approximately 2.9mm x 1.6mm, making it suitable for space-constrained PCB designs in portable and handheld devices.
Is the 74CBT1G125DBVRG4 RoHS compliant and lead-free?
Yes, the 74CBT1G125DBVRG4 is RoHS compliant and lead-free, as indicated by the 'G4' suffix in the part number and the JESD-609 Code e4. Texas Instruments manufactures this device using a lead-free soldering process, making it suitable for applications requiring compliance with environmental regulations such as RoHS and WEEE directives.
