The CY74FCT2244ATQC from Cypress Semiconductor is a 2-channel inverting buffer with 3-state outputs, part of the 74FCT high-speed logic family. It operates from 4.75V to 5.25V, providing 15mA source and 12mA sink current. The 3-state outputs enable bus sharing and high-impedance control. Packaged in a 20-SSOP, it is designed for 5V systems requiring fast signal buffering, inversion, and bus interfacing in computing, telecom, and industrial applications.
- High-Speed 74FCT Logic: Minimizes propagation delay for critical timing in 5V systems.
- 3-State Outputs: Allows multiple devices to share a bus without contention.
- 15mA Source / 12mA Sink: Drives capacitive loads and multiple inputs reliably.
- Compact SSOP-20 Package: Saves board space while providing robust thermal performance.
High-Speed 5V Bus Buffering
The 74FCT family is designed for fast propagation delays. Use this inverting buffer to drive address or data buses in 5V microprocessor systems, ensuring signal integrity at high clock rates.
Memory Address Line Driving
With 15mA source capability, it can drive multiple memory chips. The 3-state outputs allow easy bus sharing when multiple memory banks are selected via output enable signals.
Signal Inversion in Control Logic
When a control signal needs inversion, this buffer provides both inversion and fan-out. It can replace discrete inverter gates while adding drive strength for downstream logic.
Backplane Interfacing
In telecom or server backplanes, 3-state buffers are essential. This IC buffers signals between boards, with the high-impedance state preventing bus contention during hot-swap.
Industrial PLC I/O Modules
Programmable logic controllers use 5V logic. This buffer conditions sensor inputs and drives output modules, with the -40°C to 85°C range covering most industrial environments.
Test Equipment Signal Routing
In automated test equipment, 3-state buffers route test signals to different measurement points. The inverting function can be used to generate complementary test patterns.
