MC74HC573ADWR2G

The MC74HC573ADWR2G is an octal 3-state noninverting transparent latch in 20 pin WSOIC package. This device is identical in pin-out to LS573. It is compatible with standard CMOS outputs with pull-up resistors it is also compatible with LSTTL outputs. This latch appears transparent to data (outputs change asynchronously) when Latch enable is high. Data meeting the setup and hold time becomes latched when latch enable goes low. The MC74HC573ADWR2G is identical in function to HC373A but has the data inputs on the opposite side of package from outputs to facilitate PC board layout.
