Product Summary
The tc74hc541af is a high speed CMOS buffer fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The tc74hc541af has a 2 channel 3 configuration. The digital signal to the control terminal turns "ON" the corresponding switch of each channel a large amplitude signal (VCC-VEE) can then be switched by the small logical amplitude (VCC-GND) control signal.
Parametrics
tc74hc541af absolute maximum ratings: (1)supply voltage range: -0.5 to 7 V; (2)control input voltage: -0.5 to VCC+0.5 V; (3)switch I/O voltage: VEE-0.5 to VCC+0.5 V; (4)control input diode current: ±20 mA; (5)I/O diode current: ±20 mA; (6)switch through current: ±20 mA; (7)DC VCC or ground current: ±75 mA; (8)power dissipation: 500 (DIP)/180(SOP, TSSOP) mW; (9)storage temperature: -65 to 150 ℃.
