CBT3857

INTEGRATED CIRCUITS CBT3857 10-bit bus switch with 10 kΩ pull-down termination resistors Product specification Supersedes data of 1998 Dec 10 1999 Sep 14 Philips Semiconductors Philips Semiconductors Product specification 10-bit bus switch with 10 kΩ pull-down termination resistors CBT3857 FEATURES Enable signal is SSTL_2 compatible Optimized for use in Double Data Rate (DDR) SDRAM applications DESCRIPTION This 10-bit bus switch is designed for 3 V to 3.6 V VCC operation and SSTL_2 output enable (OE) input levels. When OE is LOW, the 10-bit bus switch is on and port A is connected to port B. When OE is HIGH, the switch is open, and a high-impedance state exists between the two ports. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The CBT3857 is characterized for operation from 0°C to +85°C. Flow-through architecture optimizes PCB layout Designed to be used with 200 Mbps Switch on resistance is designed to eliminate the need for series resistor to DDR SDRAM Internal 10 kΩ pull-down resistors on B port Internal 50 kΩ pull-up resistor on output enable input Full DDR solution provided when used with SSTL16857 and PCK857 Latch-up protection exceeds 500 mA per JESD78 ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101 QUICK REFERENCE DATA SYMBOL tPLH tPHL CIN COUT ICCZ PARAMETER Propagation delay An to Yn Input capacitance Output capacitan...
