74FCT162245LTPV

Overview

The IDT74FCT162245LTPV is a Fast CMOS bus transceiver from the 74FCT logic series, housed in a 48-pin SSOP package. It contains two independent 8-bit transceivers, providing a total of 16 bidirectional data channels with non-inverting (true) output polarity. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. Key electrical specifications include a maximum propagation delay of 3.5 ns at a 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

• Provides dual 8-bit bidirectional data paths for efficient system interconnects
• Features true output polarity for non-inverting signal transmission
• Supports common direction control for simplified bus management

Applications

• High-speed data bus architectures requiring bidirectional transfer
• Memory bus interfaces in computing systems
• General-purpose digital signal routing applications

Procurement Notes

Verify the specific suffix 'LTPV' against official IDT documentation to confirm pinout compatibility and package dimensions. Ensure the selected variant matches the required operating temperature range and voltage specifications for your design. Cross-reference datasheets for any revisions that may affect mechanical or electrical parameters before finalizing procurement.

Selection Notes

Select this component when a 74FCT family bus transceiver with 16-bit width and SSOP packaging is required. It is suitable for designs needing TTL-compatible I/O levels and moderate speed performance around 3.5 ns delay. Consider alternative packages like TSSOP if board space constraints differ, but verify pin-to-pin compatibility with the original design footprint.

Part Context

This part belongs to the IDT 74FCT series of Fast CMOS logic devices, which bridge the performance gap between standard TTL and advanced CMOS technologies. The 74FCT162245 specifically addresses the need for wide-data-path bidirectional buffering in legacy and mixed-voltage digital systems, offering robust drive strength and predictable timing characteristics.

Replacement Considerations

The QS74FCT162245TPV from Quality Semiconductor Inc is a documented functional equivalent with identical logical operations and pin configuration. Verify mechanical dimensions and electrical tolerances against the original datasheet to ensure seamless integration without circuit modification.
