74FCT162245ATPVCT

Overview

The Texas Instruments 74FCT162245ATPVCT is a 16-bit bidirectional bus transceiver featuring balanced output drivers. It operates within a voltage range of 4.5V to 5.5V and supports data rates up to 70MHz. The device provides symmetric drive currents of ±24mA for both high and low states, ensuring minimal system switching noise. It utilizes a 48-pin TVSOP package and functions across an extended commercial temperature range from -40°C to +85°C.

Feature Summary

• Balanced output drivers providing symmetric current capabilities
• Reduced system switching noise through matched drive strengths
• Power-off disable functionality enabling live insertion

Applications

• High-speed data bus interfaces in computing systems
• Memory bus architectures requiring balanced signal integrity
• Industrial control systems operating in extended temperature environments

Procurement Notes

Verify the specific suffix 'TVCT' against official Texas Instruments documentation to confirm the exact package type (TVSOP) and tape-and-reel orientation. Ensure compatibility with existing board layouts regarding pin pitch and thermal requirements. Cross-reference the manufacturer's latest datasheet for any recent product change notifications or lifecycle status updates before finalizing procurement plans.

Selection Notes

Select this component when balanced drive strength is critical for minimizing electromagnetic interference and signal reflections on parallel buses. It serves as a direct replacement for standard FCT16245 devices where symmetrical rise and fall times are required. Consider the TVSOP package constraints for PCB space and thermal management during the design phase.

Part Context

This device belongs to the Fast CMOS (FCT) logic family, designed as a high-speed, low-power alternative to older ABT technologies. It integrates two independent 8-bit transceivers into a single 16-bit configuration. The technology ensures high noise immunity and fast propagation delays suitable for demanding digital communication applications.

Replacement Considerations

Officially documented substitutes include the CY74FCT162245T and IDT74FCT162245ETE. Verify pinout compatibility and electrical specifications such as drive current and operating voltage before implementing any cross-manufacturer replacements.
