M74HCT244M1R

The M74HCT244M1R is one member of the M74HCT244 family which is designed as the advanced high-speed CMOS octal BUS buffer (3-state) that has some points of features: (1)high speed: tPD = 15 ns (typ.) at VCC = 4.5V; (2)low power dissipation: Icc = 4mA(MAX.) at TA=25°C; (3)compatible with ttl outputs : VIH = 2V (MIN.) VIL = 0.8V (max); (4)balanced propagation delayS: tPLH @ tPHL; (5)symmetrical output impedancE: |IOH| = IOL = 6mA (min); (6)pin and function compatible with 74 SERIES 244.

The absolute maximum ratings of the M74HCT244M1R can be summarized as:(1)Supply Voltage: -0.5 to +7 V;(2)DC Input Voltage: -0.5 to VCC + 0.5 V;(3)DC Output Voltage: -0.5 to VCC + 0.5 V;(4)DC Input Diode Current: ±20 mA;(5)DC Output Diode Current: ±20 mA;(6)DC Output Current: ±35 mA;(7)DC VCC or Ground Current: ±70 mA;(8)Power Dissipation: 500 mW;(9)Storage Temperature: -65 to +150 °C;(10)Lead Temperature (10 sec): 300 °C.
