SN74BCT244NS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT244NS is an octal buffer and line driver utilizing BiCMOS technology. It features two independent 4-bit buffers with separate active-low output-enable (OE) inputs. The device provides non-inverting data transfer from A inputs to Y outputs when OE is low, entering a high-impedance state when OE is high. It operates within a supply voltage range of 4.5 V to 5.5 V. Electrical characteristics include a maximum low-level output current of 64 mA and a typical propagation delay of 3.2 ns at 5 V with a 50 pF load.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'NS' corresponds to the SOP package configuration before procurement. Confirm that the required operating temperature range aligns with the commercial specification of 0°C to 70°C. Ensure compatibility with the 4.5 V to 5.5 V supply voltage requirements for the target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high drive strength and reduced power consumption compared to standard TTL logic. The BiCMOS architecture offers superior performance for bus driving tasks. Consider the SOP package dimensions for PCB layout constraints. Verify that the input voltage levels are compatible with the source logic family.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the OE pin?

The OE (Output Enable) pin controls the output state. When OE is low, data passes from inputs to outputs. When OE is high, the outputs enter a high-impedance state.

How is the device organized internally?

The device is organized as two independent 4-bit buffers/line drivers, each with its own separate output-enable input.
