74FCT162245LBCTPV

Overview

The IDT74FCT162245LBCTPV is a FAST CMOS 16-bit bidirectional bus transceiver from the 74FCT logic series. It integrates two independent 8-bit transceivers in a single 48-pin package, supporting non-inverting data transfer. The device operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input and output levels. Key electrical specifications include a maximum propagation delay of 3.5 ns at 50 pF load, with output drive capabilities of -24 mA for high state and 24 mA for low state. It functions reliably across an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates dual 8-bit bidirectional bus transceivers for efficient 16-bit data handling
• Provides non-inverting signal transmission with TTL-compatible I/O levels
• Utilizes FAST CMOS technology to achieve high-speed performance with low power consumption

Applications

• High-speed data bus architectures requiring bidirectional communication
• Memory interface circuits connecting processors to storage devices
• Digital logic systems needing buffered signal distribution

Procurement Notes

Verify the specific suffix LBCTPV against official IDT or Renesas documentation to confirm pinout, package dimensions, and electrical characteristics. Ensure compatibility with your system's voltage requirements and thermal constraints before procurement. Cross-reference datasheets to validate manufacturing origin and quality standards.

Selection Notes

Select this component when designing systems requiring 16-bit bidirectional data paths with TTL compatibility. Consider the 48-pin TSSOP package for space-constrained PCB layouts. Evaluate the 3.5 ns propagation delay against your system clock speeds to ensure timing margins are met under varying load conditions.

Part Context

This part belongs to the 74FCT family of high-speed CMOS logic devices manufactured by IDT, now part of Renesas Electronics. The 74FCT series is designed for applications demanding faster switching speeds than standard HC/HCT logic while maintaining CMOS power efficiency. These components are widely used in computing and telecommunications infrastructure.

Replacement Considerations

Check for direct equivalents such as the IDT74FCT162245CTPAG, which shares similar functional characteristics but may differ in package type or suffix specifications. Verify pin compatibility and electrical parameters before substitution.
