TC7MBD3245AFK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MBD3245AFK
Octal Bus Switch
The TC7MBD3245AFK provides eight bits of high-speed
TTL-compatible bus switching in a standard ’245 device pinout.
The low on-state resistance of the switch allows connections to be
made with minimal propagation delay.
The device is organized as one 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.
The device is enable to realize the shift of signal level from 5 V
to 3.3 V.
All inputs are equipped with protection circuits against static
discharge.
Weight: 0.03 g (typ.)
