Witam
Czy ktos wie jakie sa roznice pomiedzy w/w ukladami ?
Czy mozna je stosowac zamiennie ?
To samo pytanie mam dla 74374 i 74574.

Sory pomylilem sie w tytule. Chodzilo mi o 373 i 573.

Mysle, ze to pomoze :) One sie niczym nie roznia za wyjatkiem nozek !
The MC54/74HC573A is identical in pinout to the LS573. The devices are
compatible with standard CMOS outputs; with pullup resistors, they are
compatible with LSTTL outputs.
These latches appear transparent to data (i.e., the outputs change
asynchronously) when Latch Enable is high. When Latch Enable goes low,
data meeting the setup and hold time becomes latched.
The HC573A is identical in function to the HCT373A but has the data
inputs on the opposite side of the package from the outputs to facilitate PC
board layout.
