MB2245BB,557

Overview

The MB2245BB,557 is a 16-bit bidirectional transceiver manufactured by NXP USA Inc. (originally Philips Semiconductors). It features non-inverting 3-State bus-compatible outputs in both send and receive directions. The device utilizes two Output Enable inputs and two Direction control inputs to manage data flow. It operates within a DC supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. The component is housed in a 52-lead plastic Quad Flat Pack (QFP) package.

Feature Summary

• Provides 16-bit bidirectional bus interface with non-inverting 3-State outputs
• Features power-up 3-State capability to minimize external timing requirements
• Includes latch-up protection exceeding 500mA per JEDEC Std 17
• Offers ESD protection exceeding 2000V per MIL STD 883 Method 3015

Applications

• High-performance BiCMOS bus interfacing applications
• Systems requiring high output drive capabilities
• Cascaded bus architectures utilizing multiple direction and enable pins

Procurement Notes

Verify the specific ordering suffix BB against current manufacturer documentation to confirm package type and temperature range. Ensure compatibility with 5V logic levels and check for any superseded datasheets or product change notices that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component for designs requiring robust 16-bit bidirectional data transfer with independent direction control. Consider its high output drive capability and low static power dissipation. Verify that the 52-pin QFP package fits the board layout constraints and that the operating voltage aligns with the system's 5V supply rails.

Part Context

This part belongs to the MB2245 series of 16-bit transceivers with direction pins. Originally specified by Philips Semiconductors, it is now distributed under NXP USA Inc. The device is designed for applications needing high-speed data transmission with minimal switching noise due to multiple VCC and GND pins.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify pin compatibility and electrical specifications if considering alternative manufacturers' parts.
