SN74LVTH244AZQNR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH244AZQNR is an octal buffer and line driver from Texas Instruments, belonging to the LVTH logic series. It features three-state outputs and operates within a supply voltage range of 2.7 V to 3.6 V. The device provides high drive capability with output currents of -32 mA for high state and 64 mA for low state. Propagation delay is specified at 2.3 ns at 3.3 V. It is housed in a 20-pin BGA Microstar Junior package (BGA-20) and supports surface mount installation. The component is qualified for automotive applications and functions reliably across an operating temperature range of -40°C to +125°C.
