74LCXR162245MEX

Overview

The onsemi 74LCXR162245MEX is an octal bus transceiver utilizing low-voltage CMOS technology. It features non-inverting bidirectional data flow controlled by a Direction (D) pin and an Output Enable (OE) pin. The device operates within a supply voltage range of 2.0 V to 3.6 V, with a maximum propagation delay of 8 ns. It provides three-state outputs capable of driving up to 24 mA in both high and low states. The component is housed in a TSSOP-48 surface-mount package and supports industrial operating temperatures from -40°C to +85°C.

Feature Summary

• Octal bidirectional data transfer capability for bus-oriented applications
• Low power dissipation achieved through advanced CMOS fabrication
• Three-state outputs allowing connection to multiple buses

Applications

• Mobile phone systems
• Consumer electronics
• Computing platforms

Procurement Notes

Verify the specific suffix 'MEX' against official manufacturer documentation to confirm tape-and-reel packaging details. Ensure compatibility with target PCB footprint dimensions for the TSSOP-48 package. Confirm RoHS compliance status via current datasheets before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring 8-bit wide data paths at low voltages. It serves as a direct replacement for standard 74LCX245 devices where higher density or specific packaging is required. Evaluate input/output voltage levels to ensure signal integrity across the 2.0 V to 3.6 V operating range.

Part Context

This part belongs to the 74LCXH series of low-voltage bus transceivers. It shares functional similarities with other octal transceivers like the 74LCX245 but offers specific packaging options. The LCXH designation indicates enhanced features such as bushold functionality in some variants, though verification of exact feature sets per suffix is necessary.

Replacement Considerations

Check for equivalents such as the 74LCX245MTDX or 74LCXH245MTDX. Verify pinout compatibility and electrical parameters before substitution.
