74FCT162244CTPVCT

Overview

The CY74FCT162244CTPVCT is a high-speed CMOS octal buffer and line driver manufactured by Cypress Semiconductor Corp. It features four non-inverting buffers, each handling four bits of data, housed in a 48-pin TSSOP package. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. It provides three-state outputs with series resistors for controlled signal integrity.

Feature Summary

• Provides four independent non-inverting buffer channels for parallel data transmission
• Features three-state outputs allowing multiple drivers on shared buses without contention
• Incorporates series output resistors to minimize signal reflections and ringing

Applications

• High-speed parallel bus buffering in computer systems
• Clock distribution networks requiring low skew
• Data acquisition systems needing signal isolation

Procurement Notes

Verify the manufacturer designation carefully, as Cypress Semiconductor was acquired by Infineon Technologies. Ensure the specific suffix matches the required pinout and electrical characteristics. Confirm RoHS compliance status through official documentation, as legacy parts may have varying environmental declarations depending on production date.

Selection Notes

Select this component when designing systems requiring robust buffering for wide parallel data paths. The FCT logic family offers a balance between speed and power consumption suitable for 5V applications. Consider the thermal performance of the TSSOP package if high current drive or dense PCB layouts are involved.

Part Context

This part belongs to the 74FCT logic family, designed for fast clocked systems. It serves as a direct replacement for older 74FCT equivalents in existing designs. The device is integral to maintaining signal integrity in high-frequency digital interfaces where noise immunity is critical.
