74FCT166244ATPVG

Buffers, Drivers, Receivers, Transceivers Overview

The IDT74FCT166244ATPVG is a high-speed, low-power CMOS bus driver within the 74FCT logic series. It features four independent functions, each handling four bits of data, totaling 16 channels in a 48-pin Cerpack package. The device operates with true (non-inverting) outputs and supports supply voltages ranging from 4.5 V to 5.5 V. Designed as a replacement for ABT functions, it utilizes 0.5-micron CMOS technology to deliver high performance with low power consumption.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• High-speed, low-power CMOS technology provides a direct replacement for legacy ABT functions.
• Features balanced output drivers capable of sourcing -32mA and sinking 64mA.
• Includes power-off disable functionality to permit safe live insertion into systems.
• Offers low input and output leakage currents, typically less than or equal to 1µA.

• Memory address latching
• I/O port buffering
• Bus driver implementations

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type upon ordering, as datasheets indicate availability in SSOP, TSSOP, TVSOP, and Cerpack variants. Confirm that the 'V' suffix corresponds to the required ceramic flatpack configuration rather than plastic packages. Ensure compatibility with the 4.5 V to 5.5 V operating range and check for lead-free compliance requirements against the specific manufacturing date code.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit bidirectional buffer with high drive capability is required. It is suitable for applications needing balanced output drivers and power-off protection. Consider alternative packages like TSSOP if space constraints preclude the use of the larger Cerpack format. Verify that the system voltage aligns with the specified 4.5 V to 5.5 V range.
