74FCT162244ATPVG

Overview

The IDT 74FCT162244ATPVG is a high-speed, low-power CMOS bus driver belonging to the FCT series. It features four independent drivers, each handling four bits of data, providing true (non-inverting) output logic. The device operates within a supply voltage range of 4.5V to 5.5V and utilizes a 48-pin Thin Shrink Small Outline Package (TVSOP). Designed as a replacement for older ABT functions, it offers balanced output drivers with specified current capabilities and low input leakage characteristics suitable for industrial temperature ranges.

Feature Summary

• Provides four independent 4-bit non-inverting buffer channels for signal driving applications
• Utilizes advanced 0.5 micron CMOS technology for high-speed operation and low power consumption
• Features balanced output drivers capable of sourcing and sinking significant current loads
• Includes power-off disable functionality to permit live insertion without system interference

Applications

• Memory address latching in computer systems
• I/O port buffering and expansion
• Bus driver implementations in high-speed digital circuits
• Temporary storage and transmission of data across system buses

Procurement Notes

Verify the specific package designation TVSOP-48 against your PCB footprint requirements. Confirm that the operating temperature range meets your environmental specifications. Check for RoHS compliance status relevant to your manufacturing standards. Ensure pinout compatibility if replacing existing components on a board.

Selection Notes

Select this component when a quad 4-bit non-inverting buffer is required for high-speed data lines. Consider the TVSOP-48 package for space-constrained surface mount designs. Evaluate the drive strength requirements against the balanced output capabilities. Compare propagation delay specifications with other FCT series alternatives for timing-critical paths.

Part Context

This part belongs to the IDT FCT (Fast CMOS) family, designed to replace faster but more expensive ABT logic families. The 74FCT162244 variant specifically provides non-inverting buffering. Similar parts in the lineup include inverted versions or different package options like SSOP and TSSOP, offering flexibility for various design constraints while maintaining core electrical performance.

Replacement Considerations

Cross-reference with Texas Instruments CY74FCT162244 variants for potential equivalents. Verify functional compatibility with Renesas Electronics counterparts. Check Diodes Incorporated PI74FCT162244 models for alternative sourcing options.
