74FCT162240ATPACT

Overview

The Texas Instruments 74FCT162240ATPACT is a 16-bit non-inverting buffer and line driver belonging to the FCT logic series. It features a TSSOP-48 package with 16 input lines and 16 output lines. The device operates within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum static current of 5 uA and a working power supply current of 6.4 mA. Output drive capabilities include -24 mA high-level and 24 mA low-level currents. Propagation delay is specified at 4.8 ns at 5 V. It supports 3-state outputs and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides 16-bit buffering for high-speed digital signal transmission
• Features 3-state outputs for bus-oriented memory and circuit control
• Non-inverting polarity maintains signal integrity during transmission

Applications

• Bus-oriented memory and circuit control systems
• Clock drivers and buffer circuits
• High-speed data transmission interfaces

Procurement Notes

Verify component authenticity through official Texas Instruments channels or authorized distributors. Confirm the specific suffix 'TPACT' matches the required TSSOP-48 packaging and reel specifications. Check for end-of-life status as indicated by some sources, ensuring availability aligns with long-term production requirements. Validate RoHS compliance documentation before integration into manufacturing processes.

Selection Notes

Select this component when a 16-channel non-inverting buffer with 3-state capability is required for 5V CMOS logic applications. Ensure the design accommodates the TSSOP-48 footprint and thermal dissipation limits. Compare against other FCT series variants if different pin counts or inverting configurations are needed. Verify that the 4.8 ns propagation delay meets system timing constraints.

Part Context

This part belongs to the Texas Instruments FCT (Fast CMOS) family, designed for high-speed operation with low power consumption. It serves as a critical interface component in digital systems requiring signal isolation or amplification. The 16-bit configuration allows for efficient parallel data handling, making it suitable for wide-bus architectures common in computing and telecommunications equipment.

Replacement Considerations

Check for direct cross-references from Cypress (CY74FCT162240ATPVCR) or IDT (IDT74FCT162240ETPFG). Verify pin compatibility and electrical parameters such as output current and propagation delay before substitution. Ensure the replacement package type matches the existing PCB layout.
