Product Summary
The 74LVC244ADB is an octal non-inverting buffer/line driver with 3-state outputs. The 3-state outputs of the 74LVC244ADB are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Schmitt-trigger action at all inputs makes the circuit highly tolerant for slower input rise and fall times.
Parametrics
74LVC244ADB absolute maximum ratings: (1)supply voltage:-0.5V to +6.5 V; (2)input clamping current VI <0V:-50mA; (3)input voltage:-0.5V to +6.5 V; (4)output clamping current VO >VCC or VO <0V:±50 mA; (5)output voltage:output HIGH or LOW:-0.5V to VCC + 0.5 V,output 3-state:-0.5V to +6.5 V; (6)output current VO = 0 V to VCC:±50 mA; (7)supply current:100 mA; (8)ground current:-100mA; (9)storage temperature:-65℃ to +150℃; (10)total power dissipation Tamb = -40℃ to +125℃:500 mW.
