TC7MBL3245SFT/FK/FTG
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MBL3245SFT, TC7MBL3245SFK, TC7MBL3245SFTG
Low Voltage/Low Capacitance Octal Bus Switch
TC7MBL3245SFT
The TC7MBL3245S 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.
