MC145572PB

The MC145572PB is a type of high performance, inverting octal buffer operating from a 2.7 to 3.6V supply.High imped ance TTL compatible inputs significantly reduce current loading to input drivers when TTL compatible outputs provide improved switching noise performance. A VI specification of 5.5V accepts MC145572PB inputs to be safely driven fro m 5V devices. The MC145572PB is ideal for memory address driving and all TTL level bus oriented transceiver applic ations.

Features of the MC145572PB are:(1)designed for 2.7 to 3.6V VCC operation; (2)5V tolerant interface capability with 5V TTL logic; (3)supports live insertion and withdrawal; (4)ioff specification guarantees high impedance when VCC = 0V; (5)LVTTL compatible; (6)LVCMOS compatible; (7)24mA balanced output sink and source capability; (8)near zero static supply current in all three logic state(10ua);substantially reduces system power requirements; (9)latchup perf ormance exceeds 500mA; (10)ESD Performance: human bodymodel>2000V;machine model>200V.

The absolute maximum ratings of the MC145572PB can be summarized as:(1):DC supply voltage is0.5V to +7.0 V;(2):DC input voltage is between0.5V an+7.0 V;(3):DC output voltage is between0.5V and +7.0V when output in 3state;(4):DC input diode current is50mA when VI is less than GND; (5):DC output diode current is50mA when VO is less than GND;(6):DC output source/sink current is±50 mA;(7):DC supply current per supply pin is±100 mA;(8): DC ground current per ground pin is±100 mA;(9):storage temperature ranges from65°C to +150 °C.
