What are the key features of SN74BCT2241DWRE4?
- Octal 3-state buffer with integrated 33-ohm series resistors on each output to dampen bus reflections and reduce EMI
- Dual enable inputs (active-high and active-low) provide flexible bus control for bidirectional bus arbitration in multi-master systems
- BCT family BiCMOS logic combines high-speed TTL-compatible inputs with CMOS output drive for mixed-logic system integration
- 20-pin SOIC package with 50pF rated load capacitance supports high fan-out bus driving in memory and peripheral interface designs
What is SN74BCT2241DWRE4 used for?
The SN74BCT2241DWRE4 is used as a bus buffer and line driver in microprocessor address and data bus expansion circuits where signal integrity over backplane or long PCB traces is required. Its integrated 33-ohm series resistors make it suitable for high-speed bus designs where unterminated lines would produce reflections and setup time violations. It also serves in memory interface circuits, PCI/ISA bus interfaces, and industrial control backplanes that require robust 3-state bus management.

Frequently Asked Questions
How does SN74BCT2241DWRE4 support bus signal integrity?
SN74BCT2241DWRE4 includes 33 ohm series output resistors and a 50 pF load capacitance rating, helping manage ringing on unidirectional bus lines.
Which package and pin-count details should layout teams verify?
The fetched context identifies a 20-pin SOIC small-outline package, so PCB designers should confirm the R-PDSO-G20 footprint and routing clearance.
What logic-control behavior matters when replacing this bus driver?
This octal bus driver has 3-state outputs with enable low/high control behavior, so replacements must preserve the 8-channel function and enable scheme.
Which compliance detail is available for procurement review?
The fetched data lists Pbfree Code as Yes, and buyers should still verify traceability, date code, and 20-pin SOIC packaging before production release.
