MC74AC244DTEL

Overview

The MC74AC244DTEL is an octal buffer and line driver manufactured by onsemi, belonging to the AC logic series. It features non-inverting outputs with three-state capability, housed in a 20-pin TSSOP package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a high-level output current of -24 mA and a low-level output current of 24 mA. Propagation delay is specified at 9 ns at 3.3 V and 7 ns at 5 V. The component supports a maximum power dissipation of 200 mW and functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

Provides eight non-inverting buffers with three-state outputs for bus-oriented applications
Capable of driving bus lines or buffering memory address registers
Offers improved printed circuit board density through compact packaging

Applications

Memory address drivers
Clock drivers
Bus oriented transmitter/receiver circuits

Procurement Notes

Verify the specific suffix DTEL against official datasheets to confirm the TSSOP-20 package type and tape-and-reel orientation. Ensure the part number matches the exact manufacturer designation to avoid confusion with similar variants like DWG or DTR2G which may differ in packaging or reel specifications. Cross-reference RoHS compliance status directly with the manufacturer's documentation prior to procurement.

Selection Notes

Select this component when designing systems requiring octal buffering with three-state control. The AC series offers a balance of speed and drive strength suitable for general-purpose digital interfaces. Consider the 2 V to 6 V supply range compatibility with system logic levels. Verify that the TSSOP-20 footprint aligns with the PCB layout constraints and thermal management requirements for the intended application environment.

Part Context

This component is part of the broader 74AC logic family, designed for high-speed CMOS applications. It serves as a fundamental building block for digital signal routing and isolation. The octal configuration allows for efficient handling of wide data buses, reducing the component count required for parallel data transmission paths in complex electronic systems.
