Overview
The MC74LCX245DWG is an octal bidirectional transceiver from the 74LCX logic family, manufactured by onsemi. It operates within a supply voltage range of 2 V to 3.6 V and features three-state outputs. The device provides low input current and high noise immunity, making it suitable for battery-powered applications. It supports CMOS and LVTTL/TTL input levels with LVCMOS output levels. The component is housed in a 20-SOIC package and is rated for operation between -40°C and +85°C.
Feature Summary
- Octal bidirectional data bus architecture
- Low power consumption design
- High noise immunity characteristics
Applications
- Memory mapping control
- Clock drivers
- Bus-oriented communications
Procurement Notes
Verify the specific suffix 'DWG' against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering information matches the exact package type and temperature grade required for the target application environment before finalizing procurement.
Selection Notes
Select this component when an octal bus transceiver is required for systems operating at 3.3 V or 2.5 V logic levels. It serves as a direct replacement for older 74FCT245 devices in many designs due to its compatible functionality and improved power efficiency. Verify that the system's I/O requirements align with the specified drive strength and voltage thresholds.
Part Context
This part belongs to the 74LCX series of mixed-signal integrated circuits designed for low-voltage operations. The LCX series offers performance comparable to earlier generations while significantly reducing power dissipation. It is widely used in portable electronics and communication equipment where energy efficiency and signal integrity are critical.
Replacement Considerations
Check for equivalents such as the MC74AC245DWG for higher speed requirements or other 74LCX245 variants from different manufacturers. Ensure that any substitute maintains the same 20-SOIC footprint and electrical specifications to guarantee mechanical and functional interchangeability.
