SN74ACT244DWR

The SN74ACT244DWR is designed as one kind of octal buffer /driver device that is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the device passes noninverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state. Features of the SN74ACT244DWR are:(1)4.5-V to 5.5-V VCC Operation; (2)Inputs Accept Voltages to 5.5 V; (3)Max tpd of 9.5 ns at 5 V; (4)Inputs Are TTL Compatible.

The absolute maximum ratings of the SN74ACT244DWR can be summarized as:(1)Supply voltage range, Vcc: -0.5 V to 7 V;(2)Input voltage range except I/O ports: -0.5 V to Vcc+0.5 V;(3)Output voltage range, VO: -0.5 V to Vcc+0.5 V;(4)Input clamp current, IIK: +/-20 mA;(5)Output clamp current, IOK: +/-20 mA;(6)Continuous output current: ±50 mA;(7)Continuous current through each VCC or GND: ±200 mA;(8)Storage temperature range:65°C to 150°C.etc. If you want to know more information about the SN74ACT244DWR, please download the datasheet in www.seekic.com or www.chinaicmart.com .
