M50253P

M50253P is a semiconductor intergrated circuit designed for serial parallel converter of 12-bit with N-ch opendrain output (Vo 12 V max). It is widely used in extension of I/O ports for microcomputer. There are some features as follows. First is single 5 V supply voltage. Then is high voltage breakdown output (12 V). The last one is controllable by only pin: CLK, DATA.

What comes next is about the absolute maximum ratings of M50253P . The VDD-VSS (supply voltage) is from -0.3 to 7 V. The VI (input voltage) is from VSS-0.3 to VDD+0.3 V. The VO (output voltage) is from VSS to +13 V. The IO (output current) is 20 mA. The PD (power dissipation) is 350 mW. The storage temperature is from -40 to +125. The operating temperature is from -20 to +70.

The following is about the eletrical characteristics of M50253P  (Ta=25, VDD=5 V, unless otherwise noted). The maximum IDD (supply current) is 5A when input pins: VSS or VDD level and output pin: open. The maximum IDD (supply current) is 5 mA when fCLK=500 kHz, data: VSS or VDD and output pin: open. The maximum VOL ("L" output voltage) is 2 V at IOL=20 mA. The maximum IOZH (off-state "H" output current) is 12A and the maximum IOZL (off-state "L" output current) is -5A.
