IS82C52Z CMOS Serial Controller Interface

PIN SYMBOL NO. TYPE RD 1 I WR 2 I D0-D7 3-10 I/O A0, A1 11, 12 I IX, OX 13, 14 I/O SDO 15 O GND 16 CTS 17 I DSR 18 I DTR 19 O RTS 20 O CO 21 O TBRE 22 O RST 23 I INTR 24 O ACTIVE LEVEL DESCRIPTION Low READ: The RD input causes the 82C52 to output data to the data bus (D0-D7). The data output depends upon the state.
