The CD74FCT16827ATSM is a high-speed, non-inverting buffer from Harris Corporation, designed for 5V logic systems. It provides 2 channels of signal buffering with 3-State outputs, enabling bus isolation and high-current drive. Operating from 4.5V to 5.5V, it offers asymmetric output drive of 32mA source and 64mA sink, making it ideal for driving high-capacitance loads and bus lines. This buffer is well-suited for clock distribution, memory addressing, and industrial control applications.
- High Sink Current (64mA): Drives heavy loads and long traces with ease, ensuring signal integrity.
- 3-State Outputs: Provides bus isolation and allows multiple drivers on the same line.
- 74FCT High-Speed Logic: Minimizes propagation delay for timing-critical applications.
- Compact 56-BSSOP Package: Saves board space while providing robust performance.
Driving High-Capacitance Loads
Use the CD74FCT16827ATSM to drive high-capacitance loads such as long PCB traces or multiple IC inputs. The 64mA sink capability ensures fast signal transitions.
Bus Signal Buffering
Buffer signals on a 5V bus to prevent signal degradation. The 3-State outputs allow the buffer to be disconnected, enabling other devices to drive the bus.
Clock Signal Distribution
Distribute clock signals to multiple destinations with minimal skew. The high drive current maintains signal integrity across multiple fan-outs.
Memory Address Driving
Drive address lines to multiple memory devices. The buffer reduces the load on the memory controller and improves signal timing.
Industrial Actuator Control
In industrial systems, use this buffer to drive control signals to actuators or relays. The robust output stage can handle the inductive loads with proper protection.
Test and Measurement Equipment
In ATE systems, buffer test signals to a DUT. The 3-State outputs allow the test system to release the DUT pins when not in use.
