74FCT162244CTPACT

Overview

The Cypress Semiconductor Corp 74FCT162244CTPACT is a high-speed CMOS bus driver belonging to the FCT logic family. It features sixteen non-inverting outputs organized into four functional blocks of four bits each, housed in a 48-pin TSSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports three-state output control for effective bus management. Designed for surface-mount applications, it provides robust drive capability with specified output currents of 24 mA at both high and low logic states.

Feature Summary

• Provides sixteen non-inverting buffered outputs configured as four independent four-bit drivers
• Features three-state output control to facilitate efficient multi-driver bus architectures
• Utilizes CMOS technology within the FCT series for high-speed signal transmission

Applications

• High-speed data bus buffering in computer systems
• Clock distribution networks requiring precise signal integrity
• Memory interface circuits demanding controlled impedance and drive strength

Procurement Notes

Verify the specific manufacturer designation, as this part number may be associated with Texas Instruments or its acquired entities rather than Cypress directly. Confirm the exact suffix 'TPACT' against current official datasheets to ensure correct packaging and temperature grade specifications before procurement.

Selection Notes

Select this component when designing systems that require sixteen-channel non-inverting buffering with three-state capabilities. Ensure the design environment accommodates the 4.5 V to 5.5 V operating range and the thermal characteristics of the TSSOP-48 package for reliable long-term operation.

Part Context

This component belongs to the broader 74FCT162244 family of bus drivers. Variants within this family typically share identical logical functionality but differ in physical packaging options, such as SSOP or TVSOP, and manufacturing origins across different semiconductor foundries including IDT and Texas Instruments.

Replacement Considerations

Publicly confirmed substitute part numbers include CY74FCT162244TPAC and PI74FCT162244TA. These alternatives offer equivalent logical functions and pinouts, facilitating direct replacement in existing designs where the original component is unavailable.
