IDT74FCT162H245ETPA

Overview

The IDT74FCT162H245ETPA is a 16-bit bidirectional bus transceiver from the FCT series, manufactured by Integrated Device Technology. It features two independent 8-bit drivers with true output polarity and three-state outputs. The device utilizes 0.5-micron CMOS technology for high-speed operation and low power consumption. It operates within an extended commercial temperature range of -40°C to +85°C. The component is housed in a 48-pin Cerpack (CDFP) package with a 0.635 mm pitch.

Feature Summary

• High-speed, low-power CMOS replacement for ABT functions
• Bus-hold inputs prevent floating states during inactive periods
• Power-off disable feature permits live insertion without system disruption
• Low input and output leakage current characteristics

Applications

• High-performance memory mapping systems
• Clock drivers and buffering circuits
• Control line buffering in complex digital architectures

Procurement Notes

Verify the specific suffix 'ETPA' against official manufacturer documentation to confirm the 48-pin Cerpack package configuration. Ensure compatibility with existing lead-free or leaded soldering processes as indicated by the JESD-609 code. Confirm that the extended commercial temperature rating meets the operational environmental requirements of the target application design.

Selection Notes

Select this component when a 16-bit bidirectional interface with bus-hold functionality is required. The inclusion of power-off disable supports hot-swap applications. Compare drive strength and propagation delay specifications against alternative FCT family members to ensure signal integrity matches the system's timing constraints and load capacitance requirements.

Part Context

This part belongs to the IDT 74FCT162H245 family of 16-bit bus transceivers. Variants within this family differ primarily by package type, such as SSOP, TSSOP, or Cerpack, and reel configurations. The core logical function remains consistent across the series, providing bidirectional data transfer with direction control and three-state capability for efficient bus management.

Replacement Considerations

Cross-reference with Texas Instruments CY74FCT162H245 or Pericom PI74FCT162H245 devices. Verify pinout compatibility and electrical parameters before substitution. Note that package differences may require adapter solutions or PCB redesign.
