TC7MB3245CFK集成电路（IC）的信号开关多路复用器解码器规格书PDF中文资料

The TC7MB3244C, TC7MB3245C is a Low ON-resistance /

Low Capacitance CMOS 8bit Bus Switch. The low on-resistance

of the switch allows connections to be made with minimal

propagation delay time.

The TC7MB3244C is organized as two 4-bit low-impedance

switches with separate output-enable ( OE ) inputs. When OE is

low, the switch is on and data can flow from port A to port B, or

vice versa. When OE is high, the switch is open and a

high-impedance state exists between the two ports.

The TC7MB3245C requires the output enable ( OE ) input to be

set high to place the output into the high impedance.

All inputs are equipped with protection circuits against static

discharge.
