FCT162H245ATPVCTG4

Overview

The CY74FCT162H245ATPVCTG4 is a 16-bit bus transceiver from the FCT logic family, manufactured by Texas Instruments. It features two non-inverting 8-bit transceivers with three-state outputs and bus-hold inputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports TTL input levels. It is housed in a 48-pin SSOP package with a maximum propagation delay of 4.1 ns at 5V. The component is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides bidirectional data transmission via two independent 8-bit channels
• Integrates bus-hold circuitry on all inputs to prevent floating states
• Features three-state outputs for effective bus line management
• Supports direct interface with TTL-compatible logic systems

Applications

• High-speed memory buffer applications
• Clock drivers and buffered clock distribution
• Bus-oriented architectures requiring signal isolation
• Control signal routing in industrial systems

Procurement Notes

Verify the complete part number including suffixes such as 'G4' for RoHS compliance and 'CT' for tape-and-reel packaging. Confirm the manufacturer source is authorized to ensure component authenticity. Check datasheet revisions for any pinout or electrical characteristic updates prior to final design integration.

Selection Notes

Select this component when a 16-bit wide data path with bus-hold functionality is required. It serves as a suitable alternative to standard 74FCT245 devices where input holding is necessary. Ensure the system voltage aligns with the 4.5V to 5.5V operational range and that the SSOP package fits the PCB layout constraints.

Part Context

This part belongs to the Texas Instruments FCT (Fast CMOS) series, designed for high-speed digital applications. It is functionally compatible with other 74FCT162H245 variants, differing primarily in packaging and environmental compliance suffixes. The device is part of a broader family of 16-bit bus transceivers used in complex digital logic designs.

Replacement Considerations

Compatible substitutes include the CY74FCT162H245ATPACTG4 and CY74FCT162H245CTPAG. Verify package compatibility between SSOP and TSSOP options before substitution.
