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.
