TMP8255AP-5

The TMP8255AP-5 is designed as a high speed programmable input / output interface with three 8-bit I/O ports. 24 I/O ports are divided into two groups (port A and port B) which are programmable independently by control words provided by MPU. The PPI has three operation modes (mode 0, 1, 2) and is capable of versatile interface between MPU and peripheral devices.

TMP8255AP-5 has four features. (1)5V +/- 5% single power supply. (2)24 programmable I/O ports. (3)Three operation modes (mode 0, 1, 2). (4)Bit set / reset capability. That are all the main features.

Some TMP8255AP-5 absolute maximum ratings have been concluded into several points as follow. (1)Its Vcc supply voltage would be from -0.5V to +7V. (2)Its input voltage would be from -0.5V to Vcc+7V. (3)Its power dissipation would be 1W. (4)Its soldering temperature (soldering time 10 sec) would be 260°C. (5)Its storage temperature would be from -65°C to +150°C. (6)Its operating temperature range would be from 0°C to 70°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some TMP8255AP-5 electrical characteristics are concluded as follow. (1)Its input low voltage would be min -0.5V and max 0.8V. (2)Its input high voltage would be min 2.2V and max Vcc V. (3)Its output low voltage would be max 0.45V. (4)Its output high voltage would be min 2.4V. (5)Its input leak current would be max ±10uA. (6)Its output leak current (high impedance state) would be max ±10uA. (7)Its operating supply current would be max 120mA. (8)Its darlington drive current would be min -1.0mA and max -4.0mA. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
