TC7SBD384FU 2001-12-04 1 toshiba cmos digital integrated circuit silicon monolithic TC7SBD384FU single bus switch with level shifting the TC7SBD384FU provides single bit of high-speed ttl-compatible switching. the low on resistance of the switch allows connections to be made with minimal propagation delay. the device is organized as just 1-bit low-impedance switch with output-enable (oe) input. 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 internal diode which adds to power supply line is enable to realize the shift of signal level from 5 v to 3.3 v. (note 1) all inputs are equipped with protection circuits against static discharge. features operating voltage: v cc = 4.5~5.5 v high speed operation: t pd = 0.25 ns (max) low on resistance: r on = 5 ? (typ.) esd performance: machine model > 200 v human body model > 2000 v ttl level input (control input) package: usv note 1: in case that over-shoot noise is detected, this device should be used with clamp diode to prevent the next stage device from over-stress. pin assignment (top view) weight: 0.006 g (typ.) v cc 5 oe 4 a 1 2 3 gnd b j h
