74FCT16245ETPVG

Buffers, Drivers, Receivers, Transceivers Overview

The IDT74FCT16245ETPVG is a 16-bit bidirectional bus transceiver from the 74FCT logic series, manufactured by Integrated Device Technology. It features two independent 8-bit channels with non-inverting outputs and TTL-compatible input/output levels. The device operates within a supply voltage range of 2.7V to 3.6V or 4.5V to 5.5V. Key electrical parameters include a maximum propagation delay of 5ns at 50pF load capacitance, a high-level output current of -32mA, and a low-level output current of 64mA. It supports an extended commercial operating temperature range from -40°C to +85°C and is housed in a 48-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ETPVG' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering code matches the required SSOP package variant. Cross-reference the voltage range specifications with your system's power rails to confirm operation within the 2.7V-3.6V or 4.5V-5.5V limits. Confirm lead time requirements as manufacturing schedules may vary.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit bidirectional interface is needed with high drive strength and low power consumption. It serves as a direct replacement for older ABT family functions while offering improved speed and lower leakage. Consider the 48-pin SSOP package constraints for PCB layout. Verify that the TTL input thresholds are compatible with the driving logic sources in the design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the IDT 74FCT series, which utilizes 0.5-micron CMOS technology to provide high-speed performance comparable to bipolar devices but with CMOS power efficiency. The series is designed to replace legacy ABT logic families. The 74FCT16245 specifically addresses applications requiring wide voltage flexibility and robust ESD protection for reliable operation in noisy environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers include IDT74FCT16245ETE and IDT74FCT16245ETPV8. These variants share the same logical function and pinout but differ in packaging type, such as Cerpack or standard SSOP configurations. Verify mechanical dimensions and thermal characteristics before substituting.
