74FCT16244ATPAG

Overview

The 74FCT16244ATPAG is a 16-bit buffer and line driver manufactured by Renesas Electronics. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features non-inverting logic with three-state outputs. It utilizes a TSSOP-48 package for surface mount installation. The component supports an operating temperature range from -40°C to +85°C. Propagation delay is specified at 1.5 ns. High-level output current reaches -32 mA, while low-level output current provides 64 mA. Static current consumption is 5 uA.

Feature Summary

• Provides 16-bit buffering and line driving capabilities with non-inverting polarity.
• Features three-state outputs for effective bus management and isolation.
• Supports mixed 3.3V and 5V system environments through compatible input/output levels.

Applications

• Bus-oriented memory address latching
• Clock distribution and buffering
• I/O port expansion in embedded systems

Procurement Notes

Verify the specific suffix 'TPAG' against official Renesas documentation to confirm pinout and package dimensions. Confirm RoHS compliance status via the manufacturer's datasheet. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans. Ensure the ordering part number matches the exact electrical specifications required for the design.

Selection Notes

Select this component when high-speed 16-bit data transfer is required with low power consumption. The FCT logic family offers compatibility with standard TTL inputs while maintaining CMOS noise immunity. Consider the TSSOP-48 package size constraints during PCB layout. Verify that the drive strength meets the load requirements of the connected circuitry.

Part Context

This part belongs to the 74FCT series of high-speed CMOS logic devices. The series is designed for applications requiring fast switching speeds and low power dissipation. It serves as a bridge between older TTL-based designs and modern CMOS systems. The 16244 variant specifically addresses wide data path buffering needs.

Replacement Considerations

Consult official substitution guides for equivalent parts. Verify pin-to-pin compatibility and electrical parameter alignment. Ensure the replacement maintains the same package type and thermal characteristics.
