74ABT2240CSJ

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT2240CSJ is an inverting octal buffer and line driver featuring integrated 25Ω series resistors within the output stage. Designed for driving capacitive inputs of MOS memory drivers, address drivers, clock drivers, and bus-oriented transmitters or receivers, it eliminates the need for external series resistors to reduce signal ringing. The device operates with a supply voltage range of +4.5V to +5.5V and supports free air ambient temperatures from -40°C to +85°C. It utilizes a 20-lead Small Outline Package (SOP) conforming to EIAJ TYPE II standards.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package designation M20D corresponds to the required 20-lead SOP form factor. Confirm that the integrated 25Ω series resistors meet the target circuit's impedance requirements without additional components. Ensure the operating temperature range aligns with the system environment. Check for RoHS compliance documentation if material restrictions apply. Validate pinout compatibility with existing board layouts.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an inverting octal buffer with built-in termination is required. The integrated resistors simplify design by removing external components. Verify that the high impedance state during power-up and power-down prevents bus contention. Ensure the supply voltage remains within the specified limits to maintain performance characteristics.
