Overview
The Texas Instruments 74FCT162244ATPACT is a 16-bit buffer and line driver belonging to the FCT logic series. It features non-inverting outputs with three-state capability, housed in a 48-pin TSSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides high drive strength with output currents of -24 mA for high level and 24 mA for low level. Propagation delay is specified at 4.8 ns at 5 V. Static current consumption is 5 uA, while operating power supply current reaches 6.4 mA. The component supports surface mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Provides 16-channel buffering with non-inverting signal transmission
- Features three-state outputs for bus line management
- Delivers high drive current capability for reliable signal integrity
Applications
- Parallel data bus buffering in computer systems
- Clock distribution networks requiring high fan-out
- Memory interface drivers for data transfer lines
Procurement Notes
Verify the specific suffix 'TPACT' against the official datasheet to confirm tape and reel packaging specifications and moisture sensitivity level. Ensure the order matches the exact pinout and electrical characteristics defined for this variant. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by assembly standards.
Selection Notes
Select this component when a 16-bit wide buffer with three-state control is required for high-speed digital interfaces. The FCT series offers CMOS compatibility with TTL input levels. Consider the TSSOP-48 package constraints for PCB layout. Evaluate the 4.8 ns propagation delay against system timing requirements. Ensure the 5V supply rail aligns with the 4.5V to 5.5V operating range.
Part Context
This device is part of the broader 74FCT family of high-speed CMOS logic products manufactured by Texas Instruments. It serves as a 16-bit variant within the 74FCT244/74FCT162244 functional group. The product represents a transition point in the FCT lineage, offering improved speed over standard FCT devices while maintaining CMOS power efficiency. It is designed for applications demanding fast switching speeds and high noise immunity.
Replacement Considerations
Publicly confirmed substitute part numbers include CY74FCT162244CTPVC and 74FCT162244CTPVCT from Texas Instruments. These alternatives share similar functional characteristics and pinouts. Verify package compatibility and electrical parameter tolerances before substitution.
