CD74FCT162244ETMT

Buffers, Drivers, Receivers, Transceivers Overview

The CD74FCT162244ETMT is a high-speed CMOS bus driver from the FCT series, manufactured by Harris Corporation. It features four independent 4-bit drivers with true output polarity and three-state outputs equipped with series resistors. The device operates within a supply voltage range of 4.5 V to 5.5 V, typically at 5 V. It utilizes a 48-pin Thin Shrink Small Outline Package (TSSOP) with a .3 mm pitch. The component supports an extended commercial temperature range from -40°C to +85°C and includes bus hold inputs to eliminate external pull-up resistors.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Bus hold inputs eliminate the need for external pull-up resistors
• Three-state outputs with integrated series resistors
• High drive capability suitable for system memory addressing

Buffers, Drivers, Receivers, Transceivers Applications

• System memory addressing
• Clock drivers
• Buffering and bus-oriented connections

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix ETMT confirms the TSSOP-48 package and industrial/commercial temperature grade. Confirm RoHS status as datasheets may indicate non-compliance for older Harris batches. Ensure the ordering part number matches the exact pinout and electrical characteristics required for the target design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad 4-bit buffer with true logic is required. The inclusion of bus hold inputs simplifies circuit design by removing external pull-ups. Verify that the 48-pin TSSOP footprint fits the PCB layout constraints and that the 5V CMOS logic levels are compatible with the connected system components.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Harris FCT (Fast CMOS) family, designed as a high-speed, low-power replacement for earlier ABT functions. The FCT series offers improved performance over standard TTL while maintaining CMOS power efficiency. The CD74FCT162244 variant specifically provides four independent buffers with true output polarity.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Cross-reference with IDT74FCT162244ETMT or IDT74FCT162244ATMT for equivalent functionality from Integrated Device Technology. Verify pin compatibility and electrical specifications before substitution.
