Frequently Asked Questions
What type of bus switch is the SN74CBTD3384PWLE?
The SN74CBTD3384PWLE is a 5-bit TTL-compatible unidirectional bus switch in the CBT/FST/QS family. It uses an active-low enable control signal and supports 50 pF load capacitance, providing reliable bus isolation for high-speed digital data paths.
What package does the SN74CBTD3384PWLE use?
The SN74CBTD3384PWLE is housed in a 24-pin thin shrink small outline package (TSSOP), JEDEC code R-PDSO-G24. This surface-mount package offers a compact footprint suitable for high-density PCB designs in embedded and communication systems.
Is the SN74CBTD3384PWLE RoHS compliant?
No, based on the Pbfree Code being listed as No, this particular part variant is not lead-free. Engineers designing for RoHS-compliant production should verify the exact variant code and consult Texas Instruments for a lead-free alternative part number.
What are common applications for the SN74CBTD3384PWLE?
Common applications include memory bus switching, backplane isolation, processor data bus multiplexing, and signal routing in data acquisition and industrial control boards. The unidirectional architecture and TTL compatibility make it versatile for 3.3 V and 5 V mixed-voltage systems.
How does the enable control work on the SN74CBTD3384PWLE?
The SN74CBTD3384PWLE uses an active-low enable input. When the enable pin is pulled low, the bus switch is open and data passes from input to output. When the enable pin is high, the switch is disabled and the outputs are in a high-impedance state, isolating the bus.
