QS74FCT162240ATPA

Buffers, Drivers, Receivers, Transceivers Overview

The QS74FCT162240ATPA is a CMOS bus driver from the FCT series, manufactured by Quality Semiconductor Inc. It features four functional units, each handling four bits, resulting in a total of sixteen input and output lines. The device provides inverted outputs with three-state capability and includes series resistors for drive control. It operates within a voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40 °C to +85 °C. The component is housed in a 48-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transfer between two ports using four independent 4-bit functions.
• Features inverted logic polarity with three-state outputs controlled by a common direction signal.
• Incorporates hysteresis on all inputs to improve noise immunity during signal transitions.

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data bus architectures requiring level shifting or buffering.
• Memory interface circuits utilizing standard CMOS logic families.
• General-purpose digital systems needing isolated bidirectional data paths.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as Quality Semiconductor Inc, distinct from IDT or Cypress variants. Confirm the specific suffix 'TPA' corresponds to the SSOP-48 package type. Check RoHS compliance status, as some sources indicate non-compliance for this specific manufacturer part number. Ensure the inverted output characteristic matches the system design requirements compared to non-inverting alternatives.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit bidirectional buffer with inverted logic is required. The FCT series offers compatibility with standard TTL and CMOS levels at 5V operation. Consider the SSOP-48 package constraints for PCB layout. Verify that the common control direction mechanism aligns with the system's timing requirements for data flow management.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Fast CMOS (FCT) logic family, designed for high-speed applications. It serves as a direct replacement for older 74FCT series components while offering improved switching speeds. The 16-bit configuration reduces component count in wide-bus designs compared to 8-bit counterparts.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Cross-reference with IDT74FCT162240 or CY74FCT162240 equivalents. Verify pinout compatibility and electrical characteristics such as output drive strength and propagation delay before substitution.
