74FCT16244ETPV

Overview

The IDT74FCT16244ETPV is a high-speed, low-power CMOS bus driver belonging to the FCT series. It features four independent 4-bit drivers with true outputs and 3-state capability. The device operates within a supply voltage range of 4.5V to 5.5V and supports bidirectional data transfer. It utilizes 0.5-micron CMOS technology to provide performance comparable to ABT functions while consuming significantly less power. The component is housed in a 48-pin SSOP package.

Feature Summary

• Provides high-speed signal buffering and line driving capabilities for digital systems
• Features 3-state outputs that permit live insertion and system isolation during power-off conditions
• Offers high drive strength with specified output current capabilities for reliable signal integrity

Applications

• High-speed data bus buffering in computer architectures
• Clock distribution networks requiring low skew and high drive
• Memory interface circuits for address and data lines

Procurement Notes

Verify the specific suffix 'ETPV' against the manufacturer's official datasheet to confirm the exact package type (SSOP) and tape-and-reel configuration. Ensure the component meets the required RoHS compliance status for your assembly process, as older batches may differ. Cross-reference the pinout diagram with your PCB footprint to prevent orientation errors during placement.

Selection Notes

Select this component when designing systems requiring fast switching speeds with low power consumption compared to legacy TTL or standard CMOS logic. It is suitable for applications needing isolated outputs to protect downstream devices during power transitions. Consider the 48-pin SSOP package constraints regarding thermal dissipation and board space availability for dense layouts.

Part Context

This part belongs to the Integrated Device Technology FCT (Fast CMOS) family, designed to replace faster Bipolar transistor-transistor logic (ABT) functions. The series emphasizes reduced power dissipation while maintaining high-speed performance characteristics essential for modern digital communication interfaces and processing units.

Replacement Considerations

Check for direct equivalents from Texas Instruments such as the CY74FCT16244 series, which shares similar electrical characteristics and pinouts. Verify functional compatibility regarding output drive strength and propagation delay before substituting.
