74FCT16501ATPAG

Universal Bus Functions Overview

The IDT 74FCT16501ATPAG is an 18-bit registered bus transceiver housed in a 56-pin TSSOP package. It operates within a voltage range of 4.5V to 5.5V and supports industrial temperatures from -40°C to +85°C. The device features non-inverting logic with independent output enable controls for each direction, ensuring balanced ±24mA drive strength. Built on 0.5-micron CMOS technology, it offers low power consumption and high-speed performance suitable for complex digital systems.

Universal Bus Functions Feature Summary

• Provides 18-bit bidirectional data transfer capability with registered outputs
• Features independent control for each direction to manage data flow precisely
• Utilizes advanced 0.5-micron CMOS technology for high speed and low power operation

Universal Bus Functions Applications

• Memory address latching in computer systems
• I/O port buffering for peripheral interfaces
• Bus driver applications requiring registered data storage

Universal Bus Functions Procurement Notes

Verify the specific suffix 'TPAG' confirms the TSSOP-56 package and lead-free status. Ensure compatibility with existing PCB footprints and soldering profiles. Confirm RoHS compliance requirements against project specifications. Validate that the industrial temperature range meets environmental operating conditions. Check for any obsolete status or lifecycle notices from the manufacturer before finalizing procurement plans.

Universal Bus Functions Selection Notes

Select this component when an 18-bit width is required for registered bus interfacing. The independent direction control allows flexible data routing without external logic. Consider the TSSOP-56 package for space-constrained designs needing surface-mount assembly. Verify that the 5V logic level matches the system voltage rails. Evaluate the propagation delay characteristics against the target clock speeds of the application.

Universal Bus Functions Part Context

This part belongs to the FCT (Fast CMOS) family, designed as a high-speed, low-power replacement for older bipolar technologies. It integrates registration capabilities directly into the bus transceiver function, reducing board complexity. The series is widely used in legacy and modern digital systems requiring reliable data storage and transmission across parallel buses.

Universal Bus Functions Replacement Considerations

Check for direct pin-compatible alternatives such as the 74FCT16500 series if unregistered functionality suffices. Verify equivalent parts from Renesas Electronics, which acquired IDT's logic business. Ensure substitute components maintain the same 56-pin TSSOP footprint and electrical specifications.
