- BiCMOS technology combines TTL-compatible inputs with low-power CMOS drive capability for mixed-logic interfaces
- SSOP package (DBR) reduces board area by up to 50% compared to standard DIP solutions in high-density designs
Applications
The SN74BCT25244DBR is suited for data bus buffering and signal isolation in microprocessor memory interfaces, bus expansion circuits, and industrial control systems operating on 5 V TTL logic. Its 3-state outputs enable multiple devices to share a common 8-bit data bus without contention. The BiCMOS technology makes it ideal for bridging between CMOS peripheral devices and legacy TTL backplanes in embedded and telecommunications equipment.

Frequently Asked Questions
How does the SN74BCT25244DBR's 3-state output enable multi-device bus sharing in 5 V systems?
The SN74BCT25244DBR provides 3-state outputs on all 8 channels, allowing the device to disconnect its outputs from a shared data bus when the output enable pin is deasserted. This is essential for bus architectures where multiple 8-channel buffers drive a common 5 V TTL data bus, preventing bus contention and signal corruption between competing drivers.
What supply voltage range does the SN74BCT25244DBR support and how does this affect compatibility with TTL systems?
The SN74BCT25244DBR operates from a 4.5 V to 5.5 V supply voltage range, making it fully compatible with standard 5 V TTL logic levels. The BiCMOS input stage accepts TTL-threshold signals while the CMOS output stage delivers sufficient drive current across all 8 channels to interface with downstream TTL and CMOS loads in backplane or memory bus designs.
For a high-density PCB design, what board space advantage does the SN74BCT25244DBR's SSOP package offer over DIP alternatives?
The SN74BCT25244DBR in the SSOP (DBR) surface-mount package occupies approximately 30 mm² compared to over 100 mm² for a 20-pin DIP equivalent, enabling denser PCB layouts for 8-channel bus buffer applications. The small-pitch SSOP package is also compatible with standard SMD pick-and-place assembly, reducing manufacturing cost versus through-hole DIP options in high-volume production.
