74ABT2245D,118

Buffers, Drivers, Receivers, Transceivers Overview

The NXP USA Inc. 74ABT2245D,118 is an octal bidirectional bus transceiver utilizing BiCMOS technology. It features non-inverting 3-State outputs with integrated 30 Ω series termination resistors in both HIGH and LOW states to reduce line noise. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a temperature range from -40 °C to +85 °C. Key electrical parameters include a propagation delay of 3.9 ns (typical) at 5 V with 50 pF load, output drive capabilities of +12 mA / –32 mA, and quiescent supply current of 50 μA maximum when outputs are disabled.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status through official datasheets or product change notifications. Ensure compatibility with existing PCB footprints for the SO-20 package variant. Validate that the component meets all absolute maximum ratings for your specific operating environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for high-speed applications requiring reduced external termination components due to built-in series resistance. Compare performance metrics such as propagation delay and output drive strength against alternative logic families like LVC or AHCT. Consider the power dissipation characteristics and thermal requirements for dense circuit board layouts.
