Depends.
SHA224 uses the same algorithm as SHA256 but with different
init constants witch initiates 8 32-bit state variables
and output (8 32-bit state variables after transformations)
is truncated to 224 bytes.
SHA384 uses the same algorithm as SHA512 but with different
init constants witch initiates 8 64-bit state variables
and output (8 64-bit state variables after transformations)
is truncated to 384 bytes.

Best regards,
