TMP8259AP

The TMP8259AP is designed as a programmable interrupt controller. It handles up to eight vectored priority interrupts for the MCU. It is cascadable for up to 64 vectored priority interrupts without additional circuitry.

TMP8259AP has five features. (1) Eight level priority controller. (2) Expandable to 64 level. (3) Interrupt modes, interrupt mask, vectored address programmable. (4) Single +5V power supply. (5) Supports 8085A, 8086 microvomputer interrupt sequence. That are all the main features.

Some TMP8259AP absolute maximum ratings have been concluded into several points as follow. (1) Its Vcc supply voltage (with respect to Vss) would be from -0.5V to +7V. (2) Its input voltage would be from -0.5V to +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 TMP8259AP electrical characteristics about it. (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+0.5V. (3) Its output low voltage would be max 0.45V. (4) Its output high voltage would be min 2.4V. (5) Its output high voltage (INT) would be min 3.5V at Ioh=-100uA and would be min 2.4V at Ioh=-400uA. (6) Its input leak current would be max ±10uA. (7) Its output leak current would be max ±10uA. (8) Its input current would be max -300uA at Vin=0V and would be max 10uA at Vin=Vcc. (9) Its operating supply current would be max 85mA. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
