MC74LCX16245DTR2

Overview

The MC74LCX16245DTR2 is a dual octal bus transceiver from the 74LCX logic family, manufactured by onsemi. It operates with a supply voltage range of 2.0 V to 3.6 V and features non-inverting data transmission. The device utilizes a 48-pin TSSOP package and provides three-state outputs for effective bus management. Designed for low-voltage applications, it supports bidirectional data flow controlled by direction and output enable inputs.

Feature Summary

• Dual octal configuration enabling simultaneous high-speed data transfer across two independent 8-bit buses
• Low-voltage CMOS technology optimized for operation within a 2.0 V to 3.6 V power supply range
• Three-state outputs that isolate disconnected ports to prevent signal contention on shared buses

Applications

• Memory address and data bus driving in portable electronic devices
• Bidirectional level shifting between different voltage domains in system interconnects
• High-density data routing in consumer electronics requiring low power consumption

Procurement Notes

Verify the specific suffix against official documentation, as standard part numbers often include trailing characters indicating packaging or temperature ratings. Confirm RoHS compliance status and moisture sensitivity levels prior to integration. Ensure the procurement source provides valid traceability for automotive or industrial qualification requirements if applicable.

Selection Notes

Select this component when designing systems requiring dual-channel translation between 2.0 V and 3.6 V logic families. Evaluate pin compatibility carefully, as the 48-pin TSSOP footprint differs significantly from single-supply variants. Consider thermal performance and propagation delay specifications relative to the target clock frequencies of the application.

Part Context

This device belongs to the 74LCX series, which represents low-voltage CMOS technology designed for high-speed digital applications. Unlike older 5 V tolerant counterparts, this specific model focuses on sub-3.6 V operations, making it suitable for modern battery-powered systems where power efficiency is critical for extended operational life.

Replacement Considerations

Direct substitutes may include other dual octal transceivers from the same manufacturer's LCX or LVX families, provided they match the 48-pin TSSOP package and voltage specifications. Verify functional equivalence regarding input/output characteristics before replacing.
