Overview
The CY74FCT16827ATPACT is a 20-bit buffer and line driver manufactured by Texas Instruments. It belongs to the FCT logic series and features non-inverting outputs with three-state capability. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 56-pin TSSOP package. It provides high drive currents of -32 mA for high-level output and 64 mA for low-level output, ensuring robust signal integrity across its sixteen channels.
Feature Summary
- Provides 20-bit buffering with two independent 10-bit elements
- Features three-state outputs for bus-oriented applications
- Delivers high drive current capability for reliable signal transmission
Applications
- Bus-oriented memory and logic systems
- Clock drivers and buffer circuits
- High-density data acquisition systems
Procurement Notes
Verify the specific suffix 'TPACT' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and temperature grade. Ensure compatibility with existing PCB footprints for the 56-lead TSSOP package. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental information page before finalizing procurement orders.
Selection Notes
Select this component when designing systems requiring 20-bit unidirectional buffering with three-state control. The FCT technology offers faster switching speeds compared to standard CMOS alternatives. Verify that the system power supply remains within the 4.5 V to 5.5 V operating range to maintain specified electrical characteristics and propagation delays.
Part Context
This part is part of the CY74FCT16827 family of 20-bit buffers. It serves as a high-performance solution for digital signal routing in complex electronic architectures. The device complements other FCT series components like the CY74FCT16244T, providing scalable buffering options for large-scale integration projects requiring precise timing and signal conditioning.
Replacement Considerations
The CY74FCT16827ATPVCG4 is a verified lead-free replacement variant within the same functional family. Both parts share identical pinouts and electrical specifications, allowing for direct substitution in designs where lead-free compliance is required.
