Overview
The CY74FCT2244TSOCTE4 is an octal buffer and line driver from the Texas Instruments FCT logic series. It features non-inverting logic with three-state outputs, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 6.5 ns at 5 V, high-level output current of -15 mA, and low-level output current of 12 mA. Static current is specified at 100 nA, with a maximum operating temperature of +85°C.
Feature Summary
- Octal configuration providing eight independent buffering channels
- Three-state output capability for bus-oriented systems
- Non-inverting signal transmission
- CMOS technology construction
Applications
- Bus-oriented memory and address drivers
- Clock drivers
- Buffering for I/O circuits
Procurement Notes
Verify the specific suffix 'SOCT' against official Texas Instruments documentation to confirm the tape-and-reel packaging variant, as datasheets often list 'TSOC' (tube) as the standard. Ensure the E4 lead-free designation is required for compliance. Cross-reference the Mouser or DigiKey part numbers to confirm current availability status and manufacturing lifecycle stage before finalizing procurement plans.
Selection Notes
Select this component when an octal buffer with three-state outputs is required for 5V CMOS applications. The FCT series offers speed comparable to LS TTL but with CMOS power consumption. Verify that the 20-pin SOIC package fits the PCB footprint and that the 6.5 ns propagation delay meets the system timing requirements. Ensure the input voltage levels are compatible with the driving source.
Part Context
This part belongs to the CY74FCT2244T family of octal buffers. Similar variants include CY74FCT2244TSOC (tube package) and CY74FCT2244TQCT (QSOP package). The family is designed for high-speed digital applications requiring multiple buffered outputs with tri-state control on a single chip.
Replacement Considerations
Direct substitutes may include CY74FCT2244TSOC if tube packaging is acceptable. Other manufacturers offer equivalent octal buffers, such as the 74FCT244ATSOG from Renesas, though pinouts and electrical characteristics must be verified for compatibility.
