| 电源电压VccVoltage - Supply | 1.2 V ~ 3.6 V |
| 静态电流IqCurrent - Quiescent (Max) | 24mA，24mA |
| 输出高，低电平电流Current - Output High, Low | Octal Bus Transceivers (with 3-state outputs) Description This device has an active low enable input G and a direction control input (DIR). When DIR is high, data flows from the A inputs to the B outputs. When DIR is low, data flows from the B inputs to the A outputs. The HD74HCT245 transfers true data from one bus to the other. This device does not have schmitt trigger inputs. Features • LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility • High Speed Operation: tpd (A to Y) = 12 ns typ (CL = 50 pF) • High Output Current: Fanout of 15 LSTTL Loads • Wide Operating Voltage: VCC = 4.5 to 5.5 V • Low Input Current: 1 µA max • Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) • Ordering Information |
