SN74LVTH16543DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH16543DLR is a 16-bit registered bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and utilizes the LVTH logic series. The device features three-state outputs and supports LVTTL input and output levels. Key electrical parameters include a propagation delay of 5.8 ns, a maximum power supply current of 5 mA, and output drive capabilities of 64 mA for low-level and -32 mA for high-level states. It is housed in a 56-SSOP package and functions as a non-inverting latched transceiver.
