74FCT162H501CTPACT

Universal Bus Functions Overview

The Texas Instruments 74FCT162H501CTPACT is a registered bus transceiver featuring 18-bit data width and two independent circuits. It operates within a supply voltage range of 4.5 V to 5.5 V, utilizing TTL-compatible input and output levels. The device provides three-state outputs with low-level output current of 24 mA and high-level output current of -24 mA. Propagation delay is specified at 4.6 ns. It is housed in a TSSOP-56 package and supports surface-mount installation across an operating temperature range of -40°C to +85°C.

Universal Bus Functions Feature Summary

• Integrates registered bus transceiver functionality for synchronized data transfer
• Supports bidirectional data flow with independent control per circuit
• Features TTL-compatible logic levels for direct interface with standard logic

Universal Bus Functions Applications

• High-speed parallel data bus interfacing
• Registered data buffering in communication systems
• Memory interface circuits requiring latched data paths

Universal Bus Functions Procurement Notes

Verify the specific suffix 'TPACT' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Confirm RoHS compliance status directly from the latest datasheet revision. Ensure the component source is authorized to avoid counterfeit risks, as this part number may have legacy status or specific manufacturing lot requirements.

Universal Bus Functions Selection Notes

Select this component when an 18-bit registered transceiver is required for system architecture. The FCT logic family offers speed comparable to LS-TTL with CMOS power consumption. Verify that the 56-pin TSSOP footprint fits the PCB layout constraints. Ensure the design accommodates the 4.5V to 5.5V supply requirement and that the 24mA drive capability meets the load specifications of the connected buses.

Universal Bus Functions Part Context

This device belongs to the 74FCT logic family, designed for high-speed digital applications. It serves as a registered version of the non-latched bus transceiver, providing data storage at the output stage. The 18-bit configuration allows for wide data path handling in a single package, reducing component count compared to smaller bit-width alternatives.
