MC74LCX16245DTRG

Overview

The MC74LCX16245DTRG is a low-voltage CMOS 16-bit non-inverting transceiver manufactured by onsemi. It operates within a supply voltage range of 1.65 V to 5.5 V, with specific documentation noting operation from 2 V to 3.6 V. The device features byte control for efficient data management and utilizes a 48-TSSOP package. Key electrical parameters include a maximum high-level output current of -24 mA and a maximum low-level output current of 24 mA. Propagation delay is specified at 6.3 ns when tested at 2.7 V or 5.8 ns at 3 V to 3.6 V under a 30 pF load condition.

Feature Summary

• Provides 16-bit bidirectional data transmission capability in a single integrated circuit
• Incorporates byte control functionality to manage data flow efficiently
• Supports low-voltage operation suitable for modern digital systems

Applications

• High-density data bus architectures requiring 16-bit width
• Memory interface circuits utilizing byte-controlled access
• Portable electronic devices operating on low voltage supplies

Procurement Notes

Verify the specific voltage rating requirements against the 1.65 V to 5.5 V operational range before integration. Confirm that the 48-TSSOP package dimensions align with the target PCB layout constraints. Ensure that the propagation delay specifications meet the timing requirements of the system clock. Check for any obsolescence notices as availability may vary across distributors.

Selection Notes

Select this component when a 16-bit wide data path is required with byte-level control capabilities. It is appropriate for designs needing low power consumption and compatibility with both 3.3 V and 5 V logic families. Consider the 48-TSSOP package size if space efficiency is a priority. Evaluate the propagation delay characteristics against the maximum switching speed requirements of the application.
