DESCRIPTION

The SSTL16857 is a 14-bit SSTL_2 registered driver with differential clock inputs. Both VCC and VDDQ support 2.5V and 3.3V operation however.

FEATURES

• Stub-series terminated logic for 2.5V VDDQ (SSTL_2)

• Optimized for DDR (Double Data Rate) SDRAM applications

• Supports SSTL_2 signal inputs and outputs

• Flow-through architecture optimizes PCB layout

• Meets SSTL_2 class I and class II specifications

• Latch-up protection exceeds 500mA per JEDEC Std 17

• ESD protection exceeds 2000 V per MIL STD 833 Method 3015

and 200 V per Machine Model

• Full DDR solution provided when used with PCK857 and CBT3857
