74FCT162245CTPAG8

Overview

The IDT74FCT162245CTPAG8 is a dual 8-bit bus transceiver from the 74FCT logic series, housed in a 48-pin TSSOP package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. The device features balanced output drivers with maximum currents of -24 mA for high state and 24 mA for low state. Propagation delay is specified at 3.5 ns under a 50 pF load condition. It functions across an extended commercial temperature range from -40 °C to +85 °C.

Feature Summary

• Dual-channel architecture providing two independent 8-bit bidirectional data paths
• Balanced output driver capability ensuring symmetric current drive performance
• Power-off disable functionality enabling safe live insertion operations

Applications

• High-speed memory bus interfacing
• Buffering between different system clock domains
• Data routing in complex digital logic systems

Procurement Notes

Verify the specific suffix 'CTPAG8' against manufacturer documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure compatibility with existing PCB footprint dimensions and thermal requirements. Confirm that the 48-pin TSSOP variant matches the design constraints before finalizing procurement orders.

Selection Notes

Select this component when balanced drive strength is required rather than high-current applications. The FCT technology offers speed comparable to older bipolar families while maintaining CMOS power efficiency. Verify that the 4.5V to 5.5V operating range aligns with the target system's power supply specifications and noise margins.

Part Context

This part belongs to the IDT 74FCT family of Fast CMOS logic devices. These components serve as high-speed replacements for legacy transistor-transistor logic (TTL) circuits. The 162245 designation specifically indicates a dual 8-bit non-inverting transceiver structure designed for robust data transmission in demanding electronic environments.

Replacement Considerations

Cross-reference with PI74FCT162245TV or QS74FCT162245TPV for pin-compatible alternatives. Verify electrical parameter alignment, particularly output current capabilities and propagation delays, before substituting.
