The HCT238 has no latch - this may or may not be an issue for you but what this means is when you change the port pins individually, the outputs at that time will activate which may not be desired. Without knowing your exact requirements, I would suggest you look at 74HCT259 which is an addressable 8 bit latch - you have 3 address bits, a data and clock input. With this device you can set or reset any combination of bits. Also another choice maybe the 74HCT595 which is an 8 bit shift register with output latch - you use a data and clock signal to shift in the required bit pattern then toggle the output latch strobe which copies the shift register bit pattern into the outputs. You can string a number of these devices together for more outputs without having to use more port pins.

If you can tell us more output your end application, I'm sure we can give you some advice.
