TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MBL3245BFT, TC7MBL3245BFK
Octal Low Voltage
Bus Switch
The TC7MBL3245B provides eight bits of low-voltage,
high-speed bus switching in a standard ’245 device pinout. The
low ON-resistance of the switch allows connections to be made
with minimal propagation delay and while maintaining CMOS
low power dissipation.
The device comprises a single 8-bit switch. When output enable
(
OE
) is low, the switch is on and port A is connected to port B.
When
OE
is high, the switch is open and a high-impedance
state exists between the two ports.
All inputs are equipped with protection circuits to guard
against static discharge.
