SN74LVC244AN

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC244AN is an octal buffer and line driver manufactured by Texas Instruments, belonging to the LVC (Low-Voltage CMOS) logic family. It features eight non-inverting channels with three-state outputs, designed for operation within a supply voltage range of 1.65 V to 3.6 V. The device supports mixed-mode signal operations, allowing 5 V tolerant inputs while operating at lower voltages. Key electrical characteristics include a propagation delay of approximately 5.9 ns at 3.3 V, output drive currents of ±24 mA, and a maximum static current of 40 µA. It operates reliably across an extended temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'AN' against the manufacturer's official datasheet to confirm package type and pinout configuration. Ensure the selected variant matches the required operating temperature range and voltage specifications for the target application. Cross-reference ordering information with authorized distributors to confirm availability and authenticity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring octal buffering with three-state capabilities in low-voltage environments. Consider the 1.65 V to 3.6 V supply range and 5 V input tolerance for interfacing with legacy 5 V logic systems. Evaluate the propagation delay and output drive strength requirements against the load capacitance and speed constraints of the destination circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC244A series, which represents Texas Instruments' Low-Voltage CMOS logic family.
