74AC244MTC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74AC244MTC is an octal buffer and line driver belonging to the AC logic series. It features eight non-inverting inputs and outputs housed in a TSSOP-20 surface-mount package. The device operates within a supply voltage range of 2 V to 6 V, with a maximum operating temperature of +85 °C and a minimum of -40 °C. Electrical characteristics include a high-level output current of -24 mA and a low-level output current of 24 mA. Static current is specified at 4 uA, while operating power consumption reaches 40 uA. Propagation delay is 9 ns at 3.3 V and 7 ns at 5 V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the requested variant matches the required RoHS compliance status and industrial temperature rating. Cross-reference the component marking code with the datasheet to prevent substitution errors during assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state capability is required for 2V to 6V logic systems. The AC series offers faster propagation delays compared to standard HC logic. Verify that the TSSOP-20 footprint aligns with the PCB design constraints and that the thermal management strategy supports the specified operating temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AC244 family of octal buffers manufactured by onsemi. It serves as a digital logic interface component designed for high-speed applications. The device is distinct from transceivers like the 74AC245 due to its unidirectional nature and lack of direction control pins.
