What are the key features of CD74FCT541M?
- Octal (8-channel) non-inverting 3-state buffer with dual active-low output enable for unidirectional bus isolation and multiplexing
- BiCMOS FCT technology combines CMOS low power with TTL-compatible drive strength, handling 50 pF loads with fast propagation delays
- 20-pin SOIC package enabling compact SMT assembly with 8 data lines, 2 enable controls, power, and ground in a single device
What is CD74FCT541M used for?
The CD74FCT541M is used as a unidirectional data bus driver and buffer in microprocessor memory interfaces, where the 3-state outputs allow the device to disconnect from the bus during inactive cycles, preventing bus contention. Its dual output enable pins make it straightforward to implement bidirectional data paths by pairing two CD74FCT541M devices with complementary enable logic. The FCT BiCMOS family performance is also well suited for high-speed backplane buffering and address bus driving in VME, PCI, and custom embedded computing designs.

Frequently Asked Questions
How many data channels does the CD74FCT541M buffer, and what is its output state configuration?
The CD74FCT541M provides 8 non-inverting buffer channels with 3-state outputs controlled by 2 active-low output enable pins (OE1 and OE2). When either enable pin is high, all 8 outputs enter a high-impedance state, disconnecting the buffer from the bus. This allows multiple CD74FCT541M devices to share a common 8-bit data bus without contention.
What advantage does the BiCMOS FCT technology in the CD74FCT541M offer over standard CMOS bus drivers?
BiCMOS FCT combines the low quiescent power of CMOS input stages with the higher output drive strength of bipolar transistors, enabling the CD74FCT541M to drive 50 pF bus loads with propagation delays typically under 7 ns at 5 V. Standard HC CMOS buffers at the same load may be 2 to 3 times slower, making FCT preferable in systems where bus cycle time is constrained by propagation delay budgets.
In which embedded or computing bus architectures is the CD74FCT541M most commonly applied?
The CD74FCT541M is commonly used as a data bus buffer in 8-bit microprocessor systems, SRAM memory banks, and address latch interfaces where 3-state isolation is essential. It is also found in VME backplane systems, ISA bus extensions, and FPGA I/O expansion boards where multiple bus masters require orderly, contention-free access to shared 8-bit or wider data paths.
Can two CD74FCT541M devices form a bidirectional bus transceiver, and how would the enable logic be wired?
Yes. Two CD74FCT541M devices oriented in opposite directions, with their OE pins driven by complementary DIR and enable signals, create a functional 8-bit bidirectional bus transceiver. For example, when DIR is low, Device A (A-to-B direction) has OE asserted and Device B is in high-impedance state; when DIR is high, Device B (B-to-A direction) drives the bus. This approach uses standard 5 V logic signals and requires no external pull-up resistors.
