74LVTH16244TTR

Buffers, Drivers, Receivers, Transceivers Overview

The 74LVTH16244TTR is a low voltage BiCMOS 16-bit non-inverted bus buffer manufactured by STMicroelectronics. It operates within a supply voltage range of 2.7V to 3.6V and features balanced propagation delays with a maximum of 3.2ns at 85°C and VCC=3.0V. The device provides high-level output drive capabilities, including minimum currents of 32mA (IOH) and 64mA (IOL) at VCC=3.0V. It incorporates power-up/down 3-state circuitry that ensures outputs enter a high impedance state when VCC is between 0V and 1.5V, preventing driver conflicts during hot insertion.
