74LCXZ16245MTD

Overview

The Fairchild Semiconductor 74LCXZ16245MTD is a dual 16-bit bus transceiver belonging to the 74LCX logic family. It features non-inverting bidirectional data paths with separate direction control pins for each byte, enabling independent data flow management. The device operates within a supply voltage range of 2 V to 3.6 V and supports LVTTL or TTL input levels while providing LVCMOS output levels. Packaged in a 48-pin TSSOP, it offers a maximum propagation delay of 5.2 ns at 50 pF load capacitance. Output drive capability is rated at ±24 mA, ensuring robust signal integrity across industrial temperature ranges from -40 °C to +85 °C.

Feature Summary

• Dual 16-bit architecture with independent byte-level direction control
• LVTTL/TTL compatible inputs interfacing with LVCMOS outputs
• High noise immunity and low power dissipation characteristics

Applications

• Bus-oriented data routing applications
• Memory address decoding systems
• Bidirectional data path implementations

Procurement Notes

Verify the specific suffix 'Z' against official Fairchild documentation to confirm compliance status or variant details. Ensure the package type matches the required 48-pin TSSOP footprint. Confirm availability through authorized distributors as this component may be subject to lifecycle changes. Cross-reference datasheets for exact electrical specifications before integration.

Selection Notes

Select this component when designing systems requiring high-density bidirectional data transfer with mixed voltage level compatibility. The dual 16-bit configuration simplifies board layout compared to multiple single-channel devices. Verify that the 2V to 3.6V operating range aligns with the target system's power rails and that the ±24mA drive strength meets the load requirements.

Part Context

This part belongs to the 74LCX series, which utilizes advanced CMOS technology for high-speed operation with low power consumption. The 74LCXZ16245 variant specifically addresses the need for flexible bus architectures in portable and battery-powered electronics where voltage efficiency and signal speed are critical design constraints.
