SN74SSTL16847DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74SSTL16847DGGR is a 20-bit SSTL_3 interface buffer with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 3.6 V for both VCC and VDDQ, utilizing a reference voltage (VREF) between 1.3 V and 1.7 V. The device supports Class I and Class II specifications, featuring a propagation delay (tpd) from input A to output Y ranging from 1.5 ns to 3 ns depending on load capacitance. High-level output current reaches -20 mA, while low-level output current reaches 20 mA. It is housed in a 64-pin DGG package (TSSOP) and functions within an operating temperature range of 0°C to 70°C.
