Frequently Asked Questions
How many bits can the SN74CBTD3861PWRE4 switch, and in which direction?
The SN74CBTD3861PWRE4 is a 10-bit bidirectional bus switch, meaning it can pass data in either direction between its A and B ports. The active-low enable pin controls whether the switch is conducting or in the high-impedance 3-state condition, making it easy to multiplex multiple sources onto a shared 10-bit bus.
Is SN74CBTD3861PWRE4 suitable for automotive designs requiring qualification standards?
Yes, the E4 suffix indicates AEC-Q100 automotive qualification, making SN74CBTD3861PWRE4 appropriate for use in automotive body electronics, infotainment, and ADAS modules. The device operates reliably across the extended temperature range and meets the quality and reliability demands of automotive-grade production.
What package does SN74CBTD3861PWRE4 use, and how many pins does it have?
The SN74CBTD3861PWRE4 is housed in a 24-pin TSSOP (R-PDSO-G24) package, which is a thin small-outline package with fine-pitch leads. This package is well suited for high-density PCB layouts where board space is limited, such as automotive ECU boards and compact industrial controllers.
How does the CBT family's near-zero propagation delay benefit high-speed bus designs?
The CBT (complementary bus technology) family achieves near-zero propagation delay by using FET pass transistors rather than logic gates to route signals, resulting in typical delays below 0.25 ns. This makes SN74CBTD3861PWRE4 transparent to timing budgets in 50 pF loaded bus environments, unlike conventional buffer-based solutions that add gate delay.
Can SN74CBTD3861PWRE4 replace an 8-bit bus switch when 10-bit coverage is needed?
Yes, when a design requires 10 bidirectional bus lines, SN74CBTD3861PWRE4 eliminates the need for one 8-bit switch plus additional discrete switches. It provides all 10 bits in a single 24-pin TSSOP package, reducing component count and board area while maintaining TTL-compatible input thresholds and 50 pF drive capability.
