74FCT16245TPV

Buffers, Drivers, Receivers, Transceivers Overview

The IDT74FCT16245TPV is a 16-bit bidirectional transceiver utilizing 0.5-micron CMOS technology, designed for synchronous communication between two buses (A and B). It operates at VCC = 5.0V ±10% with an industrial temperature range of -40°C to +85°C. The device provides high drive outputs (-32mA IOH, 64mA IOL) and features power-off disable capability for live insertion. It supports TTL input levels (VIH min 2V, VIL max 0.8V) and includes hysteresis on all inputs. Propagation delay ranges from 1.5ns to 4.6ns depending on the specific grade.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Bidirectional data flow control via xDIR and xOE pins allows operation as one 16-bit or two independent 8-bit transceivers.
• Power-off disable outputs permit safe live insertion into backplanes without bus contention.
• High-current output drivers are optimized for driving low-impedance backplanes and high-capacitance loads.
• Input hysteresis improves noise margins for reliable signal reception in noisy environments.

Buffers, Drivers, Receivers, Transceivers Applications

• Synchronous communication interfaces between system buses
• Backplane driver applications requiring live insertion support
• High-capacitance load driving in industrial systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package suffix 'PVG' corresponds to the Shrink Small Outline Package (SSOP) variant. Confirm the temperature grade matches the required industrial range (-40°C to +85°C). Ensure the ordering code aligns with the specific speed grade (e.g., ET, CT, AT) if propagation delay specifications are critical for the design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 5V logic interface with high drive strength is required. The FCT16245 series offers balanced drive options; ensure the specific sub-model (ET, CT, AT) meets the timing requirements. Consider the CERPACK option only if military temperature ratings (-55°C to +125°C) are necessary, as the TPV indicates the standard industrial SSOP version.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the IDT 74FCT family of Fast CMOS transceivers. It serves as a high-speed, low-power replacement for older ABT functions. The device integrates direction and output enable controls to manage data flow between Bus A and Bus B, providing flexibility in system architecture design.
