IDT74FCT162H245TPA

Overview

The IDT74FCT162H245TPA is a 16-bit bidirectional bus transceiver belonging to the FCT series, manufactured by Integrated Device Technology. It utilizes 0.5-micron CMOS technology and features two independent 8-bit functions with true outputs. The device operates within an extended commercial temperature range of -40°C to +85°C and supports a supply voltage of 5V ± 10%. Key electrical characteristics include high-speed performance with typical output skew less than 250ps, low input/output leakage currents not exceeding 1µA (max), and robust ESD protection ratings exceeding 2000V per MIL-STD-883 Method 3015. It incorporates bus-hold inputs and direction control capabilities.

Feature Summary

• High-speed, low-power CMOS replacement for ABT functions
• Bus-hold inputs prevent floating states during idle periods
• Direction control enables bidirectional data flow management
• Robust ESD protection compliant with MIL-STD-883 standards

Applications

• High-speed data bus architectures requiring bidirectional transfer
• Memory bus interfaces in computing systems
• Industrial control systems operating in extended temperature environments
• Telecommunications equipment signal routing

Procurement Notes

Verify the specific package suffix 'TPA' against official IDT documentation, as standard listings often cite TSSOP or SSOP variants. Confirm RoHS compliance status, as older FCT series parts may be non-compliant. Ensure the manufacturer source is identified correctly, noting that IDT assets were acquired by Renesas Electronics. Cross-reference the full part number with current datasheets to confirm availability and pinout compatibility before procurement.

Selection Notes

Select this component when designing systems requiring 16-bit bidirectional data transfer with bus-hold functionality. It serves as a direct upgrade for legacy ABT logic families, offering improved speed and lower power consumption. Consider the -40°C to +85°C operating range for industrial applications. Verify that the required drive strength and ESD protection levels meet the system's environmental and reliability specifications.

Part Context

This device is part of the IDT 74FCT162H245 family, which includes variants like the 74FCT16245 and 74FCT162245. These components are designed to replace faster but more power-hungry ABT series devices. The family shares common 0.5-micron CMOS technology and packaging options, including TSSOP and SSOP formats, ensuring pin-to-pin compatibility across similar function codes within the FCT lineup.

Replacement Considerations

Direct substitutes include PI74FCT162H245 from Pericom/Diodes Inc and CY74FCT162H245 from Cypress/TI. Verify package dimensions and pin assignments, as suffixes vary by manufacturer. Check for updated RoHS compliance if replacing older non-compliant stock.
