74ABT2240CMTCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT2240CMTCX is an octal buffer and line driver featuring inverting logic with integrated 25Ω series resistors. It operates within a supply voltage range of +4.5V to +5.5V and supports a free air ambient temperature from -40°C to +85°C. The device utilizes a 20-lead Thin Shrink Small Outline Package (TSSOP). Propagation delays are specified between 1.0ns and 5.3ns, while output enable/disable times reach up to 6.9ns. Input clamp diode voltage is -1.2V minimum.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the TSSOP specification for the CMTC suffix. Confirm the ABT logic family compatibility with system requirements. Ensure operating conditions align with the specified voltage and temperature ranges. Check for RoHS compliance documentation if required by project standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when inverting octal buffering with built-in termination is required. The integrated resistors simplify design by removing external parts. Consider the propagation delay specifications for timing constraints. Verify that the 20-lead TSSOP package fits the available board space.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT logic family, which combines advanced BiCMOS technology with standard TTL-compatible inputs. The ABT series offers higher speed performance compared to older HC or HCT families. The 2240 variant specifically provides eight channels of buffered output with inversion functionality.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include the 74ABT2240CSC, 74ABT2240CSJ, and 74ABT2240CMSA. These variants share identical electrical characteristics but differ in physical packaging dimensions.
