74FCT16244ATPVCG4

Overview

The Texas Instruments 74FCT16244ATPVCG4 is a CMOS octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device provides high drive capability with output currents of 32 mA at logic high and 64 mA at logic low. It exhibits a propagation delay of 4.8 ns at 5 V. The component is housed in a 48-pin SSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent non-inverting buffers or line drivers
• Three-state output architecture enabling bus-oriented memory and clock driving applications
• High current drive capability suitable for direct interface to CMOS, NMOS, and TTL loads

Applications

• Bus-oriented memory and register implementations
• Clock driver circuits for system timing distribution
• Memory and I/O buffering in industrial control systems

Procurement Notes

Verify the G4 suffix indicates lead-free construction and RoHS compliance during sourcing. Confirm the specific SSOP-48 pinout matches the target PCB footprint design. Ensure the 4.5 V to 5.5 V supply requirement aligns with the system power rails. Check for any recent product change notices regarding manufacturing site transitions.

Selection Notes

Select this component when an octal buffer with three-state control is required for 5 V CMOS logic systems. The FCT series offers faster switching speeds compared to standard 74F logic families. Consider the 48-pin SSOP package constraints for board space limitations. Verify that the 64 mA low-level sink current meets the load requirements of the connected circuitry.

Part Context

This part belongs to the Texas Instruments 74FCT (Fast CMOS) logic family, designed for high-speed digital applications. It serves as an octal buffer variant within the broader 74FCT16244T series. The device complements other FCT components like latches and transceivers in complex digital system designs requiring reliable signal integrity and fast propagation delays.

Replacement Considerations

The CY74FCT16244ATPVCT is a compatible alternative within the same manufacturer portfolio. Verify pin compatibility and electrical specifications before substitution. Cross-reference datasheets to ensure identical package dimensions and thermal characteristics.
