Hot-selling and scarce SN54ALS573CJ OCTAL D-TYPE TRANSPARENT LATCHES WITH 3-STATE OUTPUTS CDIP20 spot stock

Product Descriptions

These octal D-type transparent latches feature3-state outputs designed specifically for drivinghighly  capacitive  or  relatively  low-impedanceloads .    They    are    particularly    suitable    forimplementing    buffer    registers,    I/O    ports,bidirectional bus drivers, and working registers .

While the latch-enable (LE) input is high, outputs(Q)respond to the data (D)inputs.When LE is low,the outputs are latched to retain the data that wasset up 

A buffered output-enable (OE) input can be usedto place the eight outputs in either a normal logicstate (high or low) or a high-impedance state . Inthe high-impedance state,the outputs neither loadnor   drive   the   bus   lines   significantly.   Thehigh-impedance  state  and the  increased  driveprovide the capability to drive bus lines withoutinterface or pullup components .

OE  does  not  affect  internal  operation  of  thelatches .Old data can be retained or new data canbe   entered   while   the   outputs   are   in   thehigh-impedance state
