NB4L52MNR2G

NB4L52 2.5 V/3.3 V/5.0 V Differential Data/Clock D Flip-Flop with Reset Multi−Level Inputs to LVPECL Translator w/ Internal Termination The NB4L52 is a differential Data and Clock D flip−flop with a differential asynchronous Reset. The differential inputs incorporate internal 50 W termination resistors and will accept PECL, LVPECL, LVCMOS, LVTTL, CML, or LVDS logic levels. When Clock transitions from Low to High, Data will be transferred to the differential LVPECL outputs. The differential Clock inputs allow the NB4L52 to also be used as a negative edge triggered device. The device is housed in a small 3x3 mm 16 pin QFN package. http://onsemi.com MARKING DIAGRAM* 16 1 • • Maximum Input Clock Frequency > 4 GHz Typical 330 ps Typical Propagation Delay 145 ps Typical Rise and Fall Times Differential LVPECL Outputs, 750 mV Peak−to−Peak, Typical Operating Range: VCC = 2.375 V to 5.5 V with VEE = 0 V Internal Input Termination Resistors, 50 W Functionally Compatible with Existing 2.5 V/3.3 V/5.0 V LVEL, LVEP, EP, and SG Devices −40°C to +85°C Ambient Operating Temperature These are Pb−Free Devices NB4L 52 ALYWG G QFN−16 MN SUFFIX CASE 485G Features • • • • • • • 1 A L Y W G = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package (Note: Microdot may be in either location) *For additional marking information, refer to Application Note AND8002/D.
