74FCT162500CTPVCT

Overview

The Texas Instruments 74FCT162500CTPVCT is an 18-bit registered bus transceiver in a 56-lead SSOP package. It operates at VCC = 5V ± 10% with an industrial temperature range of −40°C to +85°C. The device features FCT-C speed with a maximum propagation delay of 4.6 ns and balanced 24 mA output drivers. It supports partial-power-down mode via Ioff circuitry, which disables outputs to prevent backflow current. The component includes edge-rate control for improved noise characteristics and typical ground bounce (VOLP) less than 0.6V.

Feature Summary

• Supports transparent, latched, or clock modes through D-type latch and flip-flop combinations
• Includes Ioff circuitry for partial-power-down applications to prevent damaging current backflow
• Features edge-rate control circuitry to improve noise characteristics
• Provides balanced 24 mA output drivers with internal current limiting resistors

Applications

• Driving transmission lines
• Partial-power-down system applications
• Universal bus transceiver circuits

Procurement Notes

Verify the specific ordering code matches the required speed grade and package type. Confirm that the SSOP variant aligns with PCB footprint requirements. Ensure the industrial temperature rating meets environmental specifications. Check for RoHS compliance status if required by manufacturing standards. Validate pinout compatibility during integration planning.

Selection Notes

Select this component when 18-bit data width and registered functionality are required. Choose the CT speed grade for 4.6 ns performance. Consider the balanced 24 mA drivers for transmission line driving needs. Verify voltage levels match the 5V logic family requirements. Evaluate the need for partial-power-down support in the target design.

Part Context

This device belongs to the FCT logic family, designed for high-speed CMOS applications. It combines the speed of Fast CMOS with TTL-compatible inputs. The registered transceiver architecture allows for data storage and synchronization. It serves as a bridge between microprocessors and peripheral devices requiring wide data buses.

Replacement Considerations

CY74FCT162500ATPVCT offers a 5.1 ns speed grade in the same package.
