74FCT162245CTPVCT

Overview

The Texas Instruments 74FCT162245CTPVCT is a 16-bit bidirectional bus transceiver in the FCT series. It operates at VCC = 5V ± 10% and supports an industrial temperature range of –40°C to +85°C. The device features balanced output drivers with 24 mA sink and source currents, reducing system switching noise and typical VOLP (ground bounce) to less than 0.6V at 5V. It provides propagation delays up to 4.1 ns and output skew of 0.5 ns. Packaged in a 48-lead SSOP (O48), it includes Ioff for partial-power-down mode.

Feature Summary

• Balanced 24 mA output drivers reduce system switching noise and ground bounce
• Ioff circuitry supports partial-power-down mode operation by disabling outputs
• Edge-rate control circuitry improves noise characteristics
• Configurable as two independent octals or a single 16-bit transceiver

Applications

• Bidirectional synchronous communication between buses
• Driving transmission lines
• Partial-power-down applications

Procurement Notes

Verify the package type matches the O48 48-Lead (300-Mil) SSOP specification. Confirm the operating temperature range meets the industrial requirement of –40°C to +85°C. Ensure the supply voltage aligns with the 5V ± 10% standard. Check that the specific suffix PVCT corresponds to the required reel packaging format.

Selection Notes

Select this component when low ground bounce and reduced switching noise are critical requirements. The balanced 24 mA drivers make it suitable for driving transmission lines without external terminating resistors. Choose this over the 16245 variant if lower VOLP is needed rather than higher drive current. Verify compatibility with 5V logic levels and industrial temperature constraints.

Part Context

This part belongs to the CY74FCT162245T family of 16-bit transceivers manufactured by Texas Instruments. It shares the same functional block diagram and pin configuration with the CY74FCT16245T and CY74FCT162H245T variants. The primary distinction lies in its balanced output driver specifications compared to the high-drive or bus-hold features of other family members.

Replacement Considerations

CY74FCT162245ATPVCT offers similar functionality with a 4.5 ns speed grade. CY74FCT162245TPACT provides a TSSOP package option. Cross-reference with IDT74FCT162245CTPAG for equivalent performance in different packages.
