The SL74HC573 is identical in pinout to the LS/ALS573. The deviceinputs are compatible with standard CMOS outputs with pullupresistors, they are compatible with LS/ALSTTL outputs.These latches appear transparent to data (ie, the outputs changeasynchronously) when Latch Enable is high . When Latch Enable goeslow, data meeting the setup and hold time becomes latched.
