74lvc5 73 a document number: ds35897 rev. 2 - 2 1 of 11 www.diodes.com may 2015 ? diodes incorporated new product 74LVC573A a octal transparent d - type latch with 3 state outputs description the 74LVC573A provides eight transparent d - type latches. while the latch - enable (le) input is high, the q outputs follow the data (d) inputs. when le is taken low, the q outputs are latched at the logic levels set up at the d inputs. a buffered output - enable (oe) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or the high - impedan ce state. in the high - impedance state, the outputs neither load nor drive the bus lines significantly. the high - impedance state and increased drive provide the capability to drive bus lines without interface or pullup components. oe does not affect the int ernal operations of the latches. old data can be retained or new data can be entered while the outputs are in the high - impedance state. these devices feature inputs and outputs on opposite sides of the package that facilitate printed circuit board layout. the device is designed for operation with a power supply range of 1.65 v to 3.6 v. the inputs are tolerant to 5.5v allowing this device to be used in a mixed voltage environment. the device is fully specified for partial power down applications using i off . t he i off circuitry disables the output preventing damaging current backflow when the device is powered down. features ? supply voltage range from 1.65 v to 3.6 v ? sinks or s ources 24m a at v cc = 3v ? cmos low p ower c onsumption ? i off supports partial - power down operation ? inputs or outputs a ccept u p to 5.5v ? inputs can be driven by 3.3v or 5v allowing for mixed v oltage a pplications ? schmitt trigger action at all inputs ? typical v olp (quiet output ground bounce) l ess than 0.8v with v cc = 3.3v and t a = + 25 c ? typi cal v ohv (quiet output d ynamic voh) g reater than 2.0v with v cc = 3.3v and t a = + 25 c ? esd protection tested per jesd 22 ? exceeds 200 - v machine model (a115) ? exceeds 2000 - v human body model (a114) ? exceeds 1000 - v charged device model (c101) ? latch - up exceeds 250ma per jesd 78, class i ? all devices are: ? totally lead - free & fully rohs compliant (notes 1 & 2) ? halogen and antimony free. green device (note 3) pin assignments applications ? general purpose logic ? bus driving ? power down signal isolation ? wide a rray of p roducts such as: ? pcs, notebooks, netbooks, u ltrabooks ? network ing computer peripherals, hard d rives, cd/dvd rom ? tv, dvd, dvr, s et t op b ox notes: 1. no purposely added lead. fully eu directive 2002/95/ec (rohs) & 2011/65/eu (rohs 2) compliant. 2. see http://www.diodes.com/quality/lead_free.html for more information about diodes incorporateds definitions of halogen a nd antimony free, "green" and lead - free. 3. halogen and antimony free "green products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total br + cl) and <1000ppm antimony compounds. 1 3 2 4 5 6 7 8 v c c ( t o p v i e w ) t s s o p - 2 0 g n d 1 0 9 1 3 1 4 1 2 1 1 1 7 1 8 1 6 1 5 1 9 2 0 d 2 d 1 q 2 q 3 d 3 d 4 q 4 q 1 o e q 7 d 7 q 6 d 6 d 5 q 5 l e d 8 q 8 t o p t r a n s p a r e n t v i e w 3 2 4 5 6 7 8 9 1 3 1 4 1 2 1 7 1 8 1 6 1 5 1 9 1 1 2 0 1 1 0 v c c q 1 q 4 q 3 q 5 q 6 q 7 q 8 l e q 2 g n d o e d 3 d 2 d 4 d 5 d 6 d 7 d 8 d 1 v - q f n 4 5 2 5 - 2 0 ( ) t e r m i n a l 1 i n d e x a r e a
