74FCT162244CTPAG

Overview

The Renesas Electronics Corporation 74FCT162244CTPAG is a 16-bit buffer and line driver belonging to the FCT logic series. It features four non-inverting channels, each handling four bits, housed in a 48-TSSOP surface-mount package. The device operates with a supply voltage range of 4.5 V to 5.5 V and supports three-state outputs. Key electrical parameters include a propagation delay of 1.5 ns, high-level output current of -32 mA, low-level output current of 64 mA, and static current of 5 uA. It functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides 16-bit buffering capability through four independent non-inverting channels.
• Features three-state outputs for effective bus management and isolation.
• Supports mixed 3.3V and 5V system environments via TTL-compatible inputs.

Applications

• Memory address latching in computing systems
• I/O port buffering for peripheral interfaces
• Bus driver implementation in data processing circuits

Procurement Notes

Verify component authenticity and physical condition upon receipt. Confirm that the part number matches exactly, as suffixes indicate specific packaging or temperature grades. Check for manufacturing date codes relevant to your production timeline. Ensure storage conditions comply with moisture sensitivity level requirements to prevent damage before reflow soldering.

Selection Notes

Select this component when a 16-bit buffer with high-speed performance is required in a 48-pin surface-mount form factor. It is suitable for designs needing 3.3V/5V translation capabilities. Consider alternative packages if pin count or footprint constraints differ. Evaluate power consumption requirements against the specified static current limits for thermal management.

Part Context

This component is part of the 74FCT family, designed for high-speed CMOS applications with TTL compatibility. It serves as a standard logic interface solution for bridging different voltage domains. The TSSOP-48 package allows for compact PCB layouts in dense electronic assemblies requiring reliable signal transmission.
