CY74FCT162244CTPVC

Overview

The CY74FCT162244CTPVC is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting inputs driving three-state outputs in a 48-pin TSSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 4.8 ns at 5 V, high-level output current of -24 mA, and low-level output current of 24 mA. Static current is specified at 5 uA, with a maximum operating temperature of +85 C.

Feature Summary

• Provides eight-channel buffering for digital signals with non-inverting logic functionality.
• Integrates three-state output capability to facilitate bus-oriented architectures.
• Utilizes CMOS technology within the FCT logic family for performance optimization.

Applications

• Bus-oriented system architectures requiring signal buffering
• Memory address decoding circuits
• Clock distribution networks

Procurement Notes

Verify the specific suffix 'C' against official datasheets to confirm package dimensions and thermal characteristics. Ensure compatibility with 4.5 V to 5.5 V supply rails. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when designing systems requiring eight buffered channels with controlled impedance. The FCT series offers speed advantages over standard TTL while maintaining CMOS power efficiency. Verify that the 48-pin TSSOP footprint aligns with PCB layout constraints and thermal management requirements.
