SN74LVTH126PW Description

Short technical summary and product information.

The SN74LVTH126PW from Texas Instruments is a high-speed buffer designed for low-voltage (3.3V) operation, offering a TTL interface to 5V systems. This device features four independent line drivers, each with a 3-state output that enters a high-impedance state when its output-enable input is low.

 

Key electrical characteristics include a supply voltage range of 2.7V to 3.6V and output currents of 32mA and 64mA. The buffer supports mixed-mode signal operation, allowing 5V inputs and outputs with a 3.3V VCC, and can operate from unregulated battery sources down to 2.7V. It also features bus-hold circuitry on data inputs, eliminating the need for external pull-up or pull-down resistors.

 

Designed for reliability, the SN74LVTH126PW offers latch-up performance exceeding 100mA per JESD 78, Class II, and robust ESD protection up to 2000V (Human-Body Model). It supports hot insertion with Ioff and Power-Up 3-state capabilities.

 

The SN74LVTH126PW is supplied in a 14-TSSOP surface-mount package with dimensions of 4.40mm width. Its operating temperature range is -40°C to 85°C.
