smd99f application notes high frequency response the smd99f tolerances are guaranteed for input pulse widths and periods greater than those specified in the test conditions. although the device will function properly for pulse widths as small as 40% of the total delay and periods as small as 80% of the total delay (for a symmetric input), the delays may deviate from their values at low frequency. however, for a given input condition, the deviation will be repeatable from pulse to pulse. contact technical support at data delay devices if your application requires device testing at a specific input condition. power supply bypassing the smd99f relies on a stable power supply to produce repeatable delays within the stated tolerances. a 0.1uf capac itor from vcc to gnd, located as close as possible to the vcc pin, is recommended. a wide vcc trace and a clean ground plane should be used. device specifications table 1: absolute maximum ratings p a r a m e t e r s y m b o l m i n m a x u n i t s n o t e s dc supply voltage v cc - 0 . 3 7 . 0 v input pin voltage v in - 0 . 3 v dd +0. 3 v storage temperature t st rg - 5 5 1 5 0 c lead temperature t lead 3 0 0 c 1 0 s e c table 2: dc electrical characteristics (0c to 70c, 4.75v to 5.25v) p a r a m e t e r s y m b o l m i n t y p m a x u n i t s n o t e s high level output voltage v oh 2 . 5 3 . 4 v v cc = mi n, i oh = max v ih = mi n, v il = max low level output voltage v ol 0 . 3 5 0 . 5 v v cc = mi n, i ol = max v ih = mi n, v il = max high level output current i oh - 1 . 0 m a low level output current i ol 2 0 . 0 m a high level input voltage v ih 2 . 0 v low level input voltage v il 0 . 8 v input clamp voltage v ik - 1 . 2 v v cc = mi n, i i = i ik input current at maximum input voltage i ihh 0 . 1 m a v cc = max, v i = 7.0v high level input current i ih 2 0 a v cc = max, v i = 2.7v low level input current i il - 0 . 6 m a v cc = max, v i = 0.5v short-circuit output current i os - 6 0 - 1 5 0 m a v cc = max output high fan-out 25 unit output low fan-out 12.5 load doc #97017 data delay devices, inc. 2 4/26/2007 tel: 973-773-2299 fax: 973-773-9672 http://www.datadelay.com
