Manufacturer Part Number
TC7MBL3245BFT
Description
Octal Low Voltage Bus Switch
Manufacturer
TOSHIBA [Toshiba Semiconductor]
Datasheet
Octal Low Voltage Bus Switch
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.
