74ABT244CMTCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT244CMTCX is an octal buffer and line driver with 3-STATE outputs housed in a 20-Lead Thin Shrink Small Outline Package (TSSOP). It operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of -40°C to +85°C. The device features non-inverting buffers with guaranteed output skew, simultaneous switching specifications, and latchup protection exceeding 10V. It provides high impedance glitch-free bus loading during power cycles and includes nondestructive hot-insertion capability.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• High drive capability with 64 mA sink and 32 mA source output currents
• Guaranteed performance including output skew, simultaneous switching, and dynamic threshold noise levels
• Nondestructive hot-insertion capability with high-impedance glitch-free bus loading during power-up and power-down

Buffers, Drivers, Receivers, Transceivers Applications

• Memory and address drivers
• Clock drivers
• Bus-oriented transmitter/receiver circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the component origin as this part was originally manufactured by Fairchild Semiconductor before its acquisition by onsemi. Confirm that the TSSOP package matches the MTC20 designation and ensure the suffix 'X' indicates tape and reel packaging. Check RoHS compliance status and confirm availability through authorized distributors given the historical manufacturing timeline.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when requiring high-speed octal buffering with strong drive capabilities at standard 5V logic levels. The ABT series offers faster propagation delays compared to standard HC or HCT families. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range and utilizes a 4.5V to 5.5V power supply for optimal electrical characteristics.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ABT logic family, which combines the speed of Advanced Bipolar Technology with CMOS low power consumption. The 74ABT244 specifically functions as an octal buffer/line driver. The CMTCX suffix denotes the 20-Lead TSSOP package with tape and reel shipping configuration, distinguishing it from SOIC, SSOP, or PDIP variants.
