Overview
The onsemi 74LCXH245MSA is an octal bidirectional transceiver featuring 3-STATE outputs and patented bushold circuitry. It operates within a supply voltage range of 2.0V to 3.6V, with specific specifications provided for 2.3V–3.6V applications. The device supports 5V tolerant control inputs and delivers ±24mA output drive at VCC = 3.0V. Propagation delay is specified as a maximum of 7.0ns at VCC = 3.3V, with a maximum quiescent supply current of 10µA. It is housed in a 20-Lead Shrink Small Outline Package (SSOP).
Feature Summary
- Patented bushold input circuitry eliminates the need for external pull-up or pull-down resistors.
- Implements noise and EMI reduction circuitry for signal integrity.
- Provides high latch-up performance exceeding 500mA.
- Features 5V tolerant control inputs for mixed-voltage system interfacing.
Applications
- Bus-oriented data communication systems
- Memory and disk controller architectures
- High-speed data transmission lines
Procurement Notes
Verify the exact ordering code suffix against the manufacturer's official documentation to confirm package type and tape/reel availability. Confirm RoHS compliance status and lifecycle stage directly with the supplier. Ensure the procurement channel provides valid traceability for this component.
Selection Notes
Select this component for designs requiring low power dissipation combined with high-speed operation. The bushold feature simplifies board layout by removing external biasing components. Verify that the 2.3V to 3.6V operating range aligns with the target system voltage requirements.
Part Context
This part belongs to the LCXH family of low-voltage CMOS logic devices. It serves as a bidirectional buffer for transferring data between buses. The device is manufactured using advanced CMOS technology to achieve speed while maintaining low power consumption.
Replacement Considerations
Check for equivalent parts such as MC74LCX245DWG or MC74LCX245DWR2G from onsemi. Verify pin compatibility and electrical characteristics before substitution.
