Overview
The CY74FCT16374TPVCT is a 16-bit edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a working temperature range of -40°C to +85°C. The device features two independent 8-bit registers housed in a 48-SSOP package. Key electrical characteristics include a maximum static current of 500 µA, an input capacitance of 4.5 pF, and output drive capabilities of 32 mA high and 64 mA low.
Feature Summary
- Contains two independent 8-bit D-type flip-flops for dual-channel data storage
- Provides 3-state outputs to facilitate bus-oriented memory operations
- Edge-triggered architecture ensures precise timing control via positive edge triggering
Applications
- Bus-oriented memory implementations
- Register applications requiring high-speed data latching
- Buffering circuits for parallel data transmission
Procurement Notes
Verify the specific suffix 'TPVCT' against official Texas Instruments documentation to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with existing PCB footprints for the 48-SSOP form factor. Cross-reference RoHS compliance requirements with project specifications before finalizing procurement orders.
Selection Notes
Select this component when designing systems requiring dual 8-bit register functionality with tri-state bus interfacing. Consider the 48-SSOP package constraints for space-limited designs. Evaluate the 5.5 V maximum supply voltage limit against system power rails to ensure safe operation margins are maintained.
Part Context
This part belongs to the FCT logic family, designed for high-speed CMOS performance with TTL-compatible inputs. It serves as a specialized variant within the 74FCT series, offering enhanced switching speeds compared to standard logic families while maintaining robust noise immunity for digital signal processing tasks.
Replacement Considerations
The SN74LVC16374ADLR is listed as a manufacturer-recommended substitute. Verify pinout compatibility and voltage level differences between the FCT and LVC families before implementing any cross-family replacement strategies.
